Customer Reviews
I have had owned three analog scopes in the past twenty years, with the one that I just replaced with this Rigol being a professional-grade instrument. I also used to use a Tektronix THS720 fairly scope fairly regularly at work, so I do have some small basis of comparison for digital scopes.

This is the first digital scope that I have personally owned and I did a fair bit of research into scopes in this general price range before buying this one. One of the things you might notice in doing the same type research is that for similarly-priced, obviously competing products, there will be a number of reviews that say something along the lines of “nice, except for…” or “DOA” or “PC software doesn’t work”, etc. I would have to say it is somewhat unusual to see any current piece of tech that doesn’t have any detracting reviews. However, for this particular product, essentially all of the reviews (even non-Amazon reviews) say something very much like “it works perfectly”, or “it’s a Rigol, of course it works”. This was what tipped the balance for me to spend the extra $75-$100 and get this one.

I have used the unit quite a bit now and used a lot of the features. My impressions so far are as follows:

The general “feel” of the unit (housing, buttons, power cord, screen etc.) is very good and I have no complaints about any of it.

I found the operation of the various features to be very logical, consistent, and easy to use. Everything I have done so far (with the unit itself) has worked fine without any glitches whatsoever. It produces a LOT more information than a typical analog scope. I did have a small issue with the included software on getting the correct driver loaded, but that is covered in an FAQ on the Rigol web site and I just had to download a more current driver from National Instruments. While I have not done a great deal with the PC software, what I have done so far seemed to have work well and was also fairly intuitive.

I was a little concerned about the stated (320x200) resolution of the screen but, now that I have been using it, that was an unfounded concern and the screen is just fine for this application.

A number of the online reviews (not just on Amazon) mention fan noise. It does have a fan but, in my opinion, it is not very loud at all. In fact, if anything else is going on in the room you probably won’t even notice it.

The probes that come with it are adequate (and they do work ok) but, in my opinion, they don’t have the same quality “feel” as the rest of the unit. That being said, the probes are not proprietary and if you have existing probes that you like, they should also work fine. The menu selection for probes is per-channel and accommodates a very wide range of probe values.
In conclusion, if you need a 100Mhz scope that works, this one would be a very safe choice.

Customer Reviews
If you are still sitting on the fence, and why else would you read this, go ahead and give this scope a try. As another reviewer said, it is a professional scope on a hobbyist budget. More, this scope is easy to switch to if you have been using only an analog scope before. It easily meets all specs (as far as I could measure, it quickly became the most accurate tool on my bench), it is well built, and it has more features than most hobbyists (and quite a few professionals) will ever use. The manual is comprehensive and written in easy-to-understand English, and the graphical user interface is very intuitive. Of course, there is a bit of a learning curve, but with the amount of features this scope has, this is to be expected.

There is one fly in the ointment though: the software to control the scope from a PC. I could install it with no apparent problems under Windows 10, but it would not recognize the connected scope. I contacted the manufacturer, but they never replied. But since the GUI is so intuitive, I see no real need to control the scope from a PC, and I therefore did not go down to a four star rating. If the manufacturer would have been more responsive, I would have recommended the scope for professional use as well. But since the scope is widely used, you are likely to find an Internet forum where you can ask technical questions and get them answered. So far, however, the PC software was not among the things people discussed, and, as I said, I did not see a need for the PC software yet either.

Customer Reviews
My Tek finally died - the high voltage section was fried. I went on Amazon to see what was available. I service audio equipment as a side line. After reading the specifications of the Siglent scope I decided to buy it. It is rated as a 50 MHz scope - but I have no trouble displaying a 100 MHz signal. On feature which I did not see listed is it has a frequency counter. The frequency counter is dead on and is actually more sensitive than my TEK 5316. My signal generator only goes up to 108 MHz and it only takes about 15 Millivolts of RF for the counter to lock in.

One other thing about this scope is when I use it with a sweep generator and use channel 2 as the horizontal reference, there is no drift in the display. With both analog scoped that I had owned, the scope would need a warmup time of 10 minutes or so to be stable. There is no warm up time needed with this Siglent.

If you are looking for a general purpose scope the Siglent is excellent. I am 100% happy with it. There is only one thing about it that I had to change in my equipment stack up. On the top of my stack was the frequency counter, then the scope, then the RF generator and finally the distortion analyzer. Well with the small size of the Siglent I could not stack the frequency counter on it. So I took my 5316 out of service because my new scope is actually a better frequency counter.

The TFT display is excellent. There is a on screen menu display that will let you quickly set up the scope. The scope comes with a set up guide, a CD, two very nice probes and a USB cable. It is a compact unit that is only

Customer Reviews
Similar to other reviews, I spent a LOT of time researching before finally buying the SDS7102 scope. I've had it for 6 months now and can say that's I'm really happy with my purchase. I would recommend the EEVBlog forum review as it is quite good and covers most of the pros and cons of the scope.

A few things that I'd like to emphasize:

SIZE - This scope is very lightweight but doesn't feel cheap. There is enough heft to make it work the money!
SCREEN - The screen is really nice. Excellent colors and contrast. Easy to read. No glare.
VGA OUT - Ok, this is a bit superfluous, but it does work and it's useful to display and demo on a bigger screen or projector.
LAN INTERFACE - I just got this working the other day and it works great! Way more stable connection to the computer that the buggy USB. The only thing is that it's not documented anywhere in the manual! The trick? Read the help menu _on the scope itself_ to configure the IP addressing and ports.
SAMPLE DEPTH - 10M sample depth is really nice to capture a lot of data at a time for reviewing waveforms.

INTERFACE - As expected (and as with any other China Scopes) the user interface leaves a bit to be desired. Honestly, I've learned to think a bit more like the designers and you get the hang of it pretty quick. Just a few weird quirks with how to navigate menus.
INPUT RESPONSE - The knobs and screen have a small lag that's always there. Not a huge issue, but something I still notice. Not like a good old analog scope where it happens _as_ you turn the knob, rather here you can tell that the knob first tells the CPU to then change something on the screen, and it takes a split-second.
SOFTWARE - Also as expected, the computer software is buggy and annoying to use but it does the job and does allow scope captures (just for some reason the captures don't show the scales...I need to find out if that's a user-error issue).
UPDATE Dec 2012: The LAN function on this scope is awesome! I finally found the instructions for it in the help menus in the actual scope (not in the manual) and that tells you how to setup the LAN system to let you get much better and quicker captures which is less buggy than the USB.

Overall impression? Worth it. No doubt. I've very pleased with the scope's performance. If you're in the market for a good DSO for moderate to advanced project work and don't need the higher speed for baseband debugging, then this is the scope for you.

Product description

The Owon HDS1021M is a handheld electrical test device that combines a 20 MHz, single-channel, handheld digital oscilloscope for viewing electrical signals with a manual- and auto-ranging digital multimeter for measuring AC and DC voltage to 400V, AC and DC current to 20 amp, resistance to 40 MΩ, and capacitance to 100 μF. The oscilloscope has maximum real-time sample rate of 100MS/s and a record length of 6,000 points for acquiring detailed waveforms. Its 18 automatic measurements such as period, frequency, and peak-to-peak enable an in-depth analysis of waveforms. Up to four waveforms can be stored in the internal memory. The multimeter has two ranging modes: manual, which allows the user to select the operating range, and auto, which automatically selects the appropriate operating range. The delta relative function allows a measurement to be set as a reference value and displays subsequent measurements as a positive or negative deviation from that value, and the data-hold function freezes a reading on the display to aid documentation. A continuity buzzer confirms that the circuit conducts electricity, and a diode check detects whether a circuit's diodes are working properly. Additional specifications include a rise time of 17.5 ns and various triggering features. The unit has a 3.5" color TFT (thin film transistor) LCD with a resolution of 320 x 240 pixels for viewing waveforms and measurements. An oscilloscope is used for electronics applications such as product design, assembly lines, repair and servicing, and electrical engineering education, among others. A multimeter is an electrical testing tool for measuring multiple properties of an electrical circuit to verify proper operation or diagnose problems.

Customer Reviews
This is a great little scope for the price. I couldn't find anything else comparable that didn't cost a lot more. It does everything it's supposed to. The screen is very bright and high contrast making it easy to read. The scope and frequency displays are very accurate. The manual was written by someone for whom English is a second language, but it covers all the details of operating the unit's functions adequately.

My only complaint is with the USB connection and software. If you want to use this with a PC then you're on your own. There's only 6 sentences in the user's manual section about it. Basically it just says to connect the USB cable and then install and run the software! The software on the provided CD wouldn't load at all on my Windows 7, 64 bit PC. It just gave an error saying that the software couldn't be installed properly.

Hunting around on the web I found a page on the company website at [...] which has PC software for download which does work.

The software is of minimal use. It's scan rate is very slow, updating only a few times per second from the scope to the PC. It's okay if just want to capture and freeze a waveform on the scope and then upload and convert it to an image file.

I give this scope 5 stars for it's quality, functionality, and price as a stand-alone handheld device, but subtracted one star from the five because of the PC connectivity and use issues..

Customer Reviews
I've had this scope on my home bench for about a week now, and I'm still just beginning to discover its capabilities. This relatively tiny box contains more function and capability than any oscilloscope I've ever used.

In the decades since I first learned to use an oscilloscope there's been a revolution in o-scope design. The scopes I learned on were purely analog (the first ones were all vacuum tube!) HPs and B&Ks with preamps coupled directly to the deflection circuits of a CRT. Later, in the research lab I worked in through grad school, we had solid state storage scopes from Tektronix, but they still used CRTs. Today's scopes are really instrumentation amplifiers and A/D converters coupled to computers with LCD displays, and the amount of power and flexibility available in a tiny, relatively    inexpensive scope is mind boggling. (The Tektronix under test uses 10x over sampling in the A/D conversion).

The last Tectronix scope on my home bench prior to the arrival of this unit was a unit from the 1970s I bought used back in the early 1990s. It was a two channel scope that probably cost new, in today's dollars, something like $10,000 or more. It had a triggered time base, spaces for two preamps, and that was it. It was also the size of a small window air conditioner, and had its own cart to make it portable. But inside it was an amazing example of high quality construction of the type you usually only see in aerospace components. Where B&K used fiberboard tie strips to connect components and HP used turret boards, Tectronix used silver-plated ceramic strips. Resistors were all metal film units. Soldering was all Mil-spec.

The scope under review, made in China for Tektronix, is part of their least expensive line of o-scopes. It may not have the same level of construction as that 1970s era scope I once owned, but functionally, it's light years beyond that scope. At home, I use oscilloscopes in amateur radio, for servicing and signal monitoring, and in repairing, modifying, and building guitar amplifiers, effects, and stereo components. With the four channel capabilities of this scope I can simultaneous look at (for example) all inputs and outputs of both channels of a stereo preamp. The four traces are color coded to the scope channels, too, so there's no ambiguity as to what you're looking at on the screen.

I'm still studying the manual and experimenting with settings, but among the things I've discovered so far are that the scope will automatically compute things like RMS, peakvalues, duty cycle, phase delay, pulse width, and more. It can add and subtract channels,and do a real time FFT. You can log your data directly to a USB keychain and transfer it to a computer, or print output directly to an attached printer. I can take snapshots of waveforms, and expand them for a closer look. The 70MHz bandwidth means that I can look at RF output from my radio equipment up through 6M. Front panel too confusing? There's a built-in HELP system accessible from the front panel that explains the various controls and options- in ten different languages.

If all the power in the scope itself isn't enough, you can connect it to your PC via the build in USB interface, and Tectronix even supplies a free copy of their special edition of National Instruments' Labview software, an industry standard data logging and control system that in its full version sells for $999 and up. No doubt National Instruments is hoping that institutional and commercial buyers will see the advantage in buying the full version, but for individual users like me, the limited edition is more than enough power. It looks like you can even do things like signal averaging with it, which means this would be a relatively inexpensive way to do evoked potential neurological recordings, with a suitable preamp.

Then there's Tektronix' limited 'lifetime' warranty- certainly a plus for a device this costly. It covers all repairs due to defects up to five years beyond the discontinuance of the product line, for a minus of ten years after purchase, so even after the scope is no longer made Tek will repair or replace it. While it's not a true lifetime warranty it's a lot better than the 90 day or 1 year warranties that come with most electronic gear these days.

Last, the scope comes ready to use, complete with four low capacitance 100MHz probes (and an automatic, one-button probe compensation function). You don't need to anything to put it right to work on your bench. Just plug it in, turn it on, attach the probes and you're ready to go. This is an amazingly powerful piece of equipment, and with the supplied warranty, I know it'll be working for at least a decade.

I'm just a hobbyist, assembling the basics of a proper electronics lab. This is my first oscilloscope. This model was a no-brainer (even before enabling all features via license key), between features and great build quality for the price. Let's be clear: it's not a Tek, Agilent or LeCroy, and it has a few minor annoyances I describe below. But at the price, it can't be beat, and it frankly does far more than the typical hobbyist needs.
The build quality is very solid (you will actually use the carrying handle!), the display is clear, the controls feel good. The fan is relatively loud (indeed, a common hack is to replace the fan with a quieter one), but its noise is neutral and I don't find it particularly annoying. The intensity knob, which functions as the all-purpose rotary knob for many menu items, is also the select button for those items, and as others have reported, it's very easy to accidentally slip to the next menu item when selecting. I suggest using your thumb to press the knob while holding the top of the scope. Rigol should probably change this to a knob with detents.
The software is fine (the menus take a bit of getting used to, though I can't compare to any other vendor), though occasionally its Chinese roots shine through with minor errors in English. It has on-screen help that comes in very handy. At any time, you press Help, and then press the control you want to learn about. I'd love to see this style of help on all kinds of devices.

Only a getting started guide is included as a printed manual. The full manual is a PDF. It's detailed enough, but is written with a knowledgeable user in mind -- it doesn't explain to a novice like me why and when I would use a particular option. Given how incredibly popular this model (and its older siblings) has been with hobbyists, Rigol might do well to write a manual geared towards beginner, a general digital oscilloscope primer in essence. For example, the manual doesn't explain why you would choose a lower or higher memory depth, even though it clearly affects display refresh speed. (The manual reminds me of a typical SLR camera manual, which is great if you understand photography    well, and useless if you don't!)

Customer Reviews
This is a very flexible power supply and has a decent UI. The rotary keypad is odd, as others have commented and I'm not sure why Rigol chose this since there other stuff has a normal layout. You might see some complaints on places like the EEVblog about overheating but in my unit (made July 6, 2015, this is not a problem. This unit also has firmware 1.14 which corrects some other issues you might read about.

Why not 5 stars? Simple, this supply arrived with channel 1 significantly out of calibration. That is the voltage you set using the keypad was neither the voltage you got or the voltage you read on the display. There are calibration procedures available in a manual you can download from Rigol NA's website. Have a 5 1/2 digit DMM available and be prepared to spend some time with the 40 point procedure. Now the instrument is correct for all three channels +/- about 15 mV. If you do this, the password for the manual calibration is "2012" It was odd that only channel 1 was off.

Another issue that most likely will not bother most users is the presence of a 12-14 Vrms AC voltage between each of the output terminals and chassis ground. Most of the time you would not care since you would want the DC output to float with regard to ground (be isolated) but this is still odd. See the attached scope

Customer Reviews
Read several reviews and watched a few YouTube tear downs and demos.
Because of the lower price on Amazon and Siglent was offering a free serial
protocol decode unlock key for a limited time I thought I'd give it a shot.
So far so good. I especially like the large crisp display and the
very intuitive menu system. Fan is quiet. Tons of features and functions.
Fast booting. Memory depth and screen update is pretty awesome
for a scope in this price range.

Cons so far: Power button is not a real on / off ac switch, seems to just
go into "sleep" mode with the power button throbbing green.
Sort of annoying to me.
Included software for scope capture and control
for Win-Tel PC is pretty lame when you can get it to work.
No biggie. Front heavy! Keep the feet in front in "out" position.
Serial decoding is very basic, and tweaky.

I spent a long time researching various oscilloscopes. It got to be fairly evident that the Siglent 1100X line clearly gave the best performance per dollar invested of any of these instruments. Once I received the scope, I was delighted to find that my research had paid off. The scope is very easy to use and certainly meets all of its specifications. I am especially impressed with the extensive manual which goes through every function with sufficient detail and clarity to make it easy to use all of the features and functions.

Product description

Siglent's new SDG2000X series of function generators offer a 1.2 GSa/s interpolated sample rate with 16 bits of vertical resolution. The proprietary TrueArb & EasyPulse techniques help to solve weaknesses inherent in traditional DDS generators when generating arbitrary, square, and pulse waveforms. Siglent's EasyWave arbitrary waveform software is included.

Customer Reviews
Despite some issues this is a very capable unit with good performance at a very reasonable price.

o The fan is very quiet.
o In general the user interface is good, although in some areas it is awkward.
o I find the touch-screen to be useful for some things, and will often use both the touch-screen and the buttons together to make settings.
o The manual is very basic, and inadequate in many areas.
o The EasyWave software for creating and downloading arbitrary waveforms pretty much sucks. It's also Windows only.
o The unit has two arbitrary waveform generation modes: DDS and TrueArb. They behave quite differently. The manual doesn't explain at all well the differences and how to get predictable results from either mode. The EasyWave software doesn't help at all: it will show you one thing on the computer screen and the unit will generate an entirely different waveform. After many hours of experimentation I still haven't figured out how to get predictable results, even though the waveforms I'm trying to generate should be trivial to create.
o The hardware is the same for all three units in this line. It's possible to start with the 40MHz unit, and get unlock codes for the higher frequency units.
o The only difference between the three units in this line is the maximum sine wave frequency. The maximum square-wave, triangle-wave, etc. frequencies are the same, and are lower than that for sine waves.

o There is a long discussion of issues and findings with regard to this unit on the EEVblog forum, including many oscilloscope screen shots, at:[...]
