    Love it!
    I was looking for a Function Generator that doesn't cost me an arm and a leg, while providing sufficient functionality for a hobbyist. I decided to buy this one, even though it's in the lower price range. After watching reviews on YouTube, I was confident that I would like it.Once it was on my table, I was really impressed. It's nicely built and the screen is brilliant. The signals are smooth and have less noise than my Oscilloscope which has a noise floor of some 300 uV RMS. I can't tell any difference in the noise level, when I connect the UTG962E. One thing that I particularly appreciate is the DC output (also with less noise than I can measure), which has far less noise than my switching power supplies (of course with limited current).Square wave rise time is 15 ns as specified, which is good enough (if I need steeper slopes, I can always run it through a SN74AC15 to get 2.5 ns rise time).I tested the Frequency counter (under Utility) against a PPS (Pulse Per Second) signal from a GPS and it turned out, that the time base of the UTG is only 1.7ppm off. This is better than my oscilloscope.The user interface is very intuitive and flexible. Very easy to change from "Amplitude and Offset" to "Low and High", from Frequency to Period, etc. Well thought out.I only have one point that I find a bit unfortunate: When changing parameters, the output looses it's phase.It's not a problem, when both outputs are Phase locked and one of the output is used to change phase. That works fine. However, if I want to compare the UTG output against another source with a similar frequency, it is a random number game to set the phase relationship between the two sources (like a 1 Hz signal from the UTG against a 1 Hz PPS from a reference). But this is a small thing. That's why I still give it 5 stars.All in all. It is far more that I expected and I need for my hobby, where ppm level is good enough.The movie shows the 1PPS from the GPS (yellow, used to trigger) against a sine wave with set frequency on the UTG of 1.00000179 MHz (cyan). There is very little jitter. (It also shows, how the phase jumps, when a parameter is changed).The picture shows the Frequency measurement of the 1PPS signal from the GPS. Done this for a few days now, it is constantly around 1.7 ppm off.

    Although, I did have to deal with a slight quality issue. It was no big deal. The unit was packaged very well. But after opening the box to remove the unit, there was a metalic rattling sound inside of it. Being the electronic technician that I claim to be, I couldn't resist but to remove the 4 rear screws to separate and open the enclosure (which broke the warranty seal on the bottom of the unit). Oop's! So, sue me! Anyway, I then found a small screw floating around in there. It was from the lower rear corner of the circuit board mount plastic peg that was slightly split in half. Thus, the screw may have been overtightened during factory assembly and fell out during shipping. Again, no big deal since there are 3 more screws securely holding the circuit board in place. Upon further internal inspection, I was impressed with the quality of the soldering and component layout. After re-assembly, I was now ready to power it on with complete confidence that a loose screw would not cause a short and let that nasty white smoke appear. After powering the unit on I was initially impressed with the crisp and bright TFT display. I then ran it through its functional paces and waveforms through my very expensive 100 MHZ TEK-TRO-NIX DSO. So, now I am also impressed with the UTG932E's performance up to its 30 MHZ Spec and functionality in considering low jitter/iteration/distortion and overall accuracy. Keep up the good work UNI-TREND! And don't be too discouraged by one loose screw. When there are 3 more to count on!...

    First, let me say that this is a very good 60MHz generator for $140. There are a number of generators from different Chinese companies that are very similar. I wouldn't be surprised if they all used some variant of the same main board. I tried out one these a couple of years ago - the Koolertron GH-CJDS2 which is similar in size to the UNI-T. It was a 60MHz generator also, but I returned it due to some output stability issues and spectral purity problems. Like a lot of other products from these small Chinese companies, quality and consistency can be hit or miss.

    The same may ultimately be said for this generator as more reviews get posted.

    UNI-Trends has a website where you can download a full manual for the 962 along with software for the arbitrary waveform function. I suggest you take advantage of the manual as it covers the operation of the generator thoroughly. Pay attention to the specifications so you'll know what it can and can't do. At this price point, there will be limitations compared to a full size bench generator from Siglent or Rigol. Know what you want to use it for and evaluate the specs based on that.

    For me, I wanted a small generator I could easily move around as needed and my use would primarily be for RF sinewaves in the HF spectrum. This review reflects my opinions based on that application.
    I thoroughly tested the 962 to be sure it would meet my needs. I used the following to evaluate the unit.

    Teledyne-Lecroy Wavesurfer 500MHz scope
    Siglent 3032 Spectrum Analyzer
    Keithley 2015 6.5 digit DMM and THD meter
    TTI TF-930 10 digit frequency counter with GPSDO timebase
    Mini-Circuits FCPM-6000RC RF power meter

    I first ran-in the 962 for 100 hours with both channels operating at 2 Vp-p, 10MHz into 50 Ohm loads.
    All measurements were take after a 60 minute warm-up of the test equipment and the 962 generator.
    At this point, I would like to mention that the 962 offers a choice of output impedance, It's continuously adjustable from 10 Ohms to 1000 Ohms. This is a critical feature for me as I use 50 Ohms primarily and 600 Ohms on occasion. I have not yet measured the output impedance, but am satisfied based on my other tests that it is probably spot on 50 Ohms. Using the 50 Ohm output Z does limit the output amplitude to 5 volts at higher frequencies. This is not a problem for me as I generally use levels well below that.

    First let's talk about output amplitude accuracy. In a word, it's excellent. Across a number of frequencies and output levels, it consistently measured within 1% on Channel One and 1.5% on Channel Two.

    Amplitude stability was also excellent with usually less than a couple of microvolts variation over a 1 hour period for both channels. Measurements were taken from 63mVp-p to 4.4Vp-p over several frequencies.

    Frequency accuracy and stability were remarkable for a piece of gear in this price range. Variations were on the order of 1.5ppm or less for 50kHz to 60MHz. The specs state +/-50ppm - so maybe I got a really good one.

    Spectral purity - here's where most of the inexpensive generators fall flat. The 962 is not without problems. On the plus side, the specs call for harmonics of the fundamental output to be a minimum of -40dB down for 30MHz to 60MHz. I generally found harmonics to be around -60dB down or better for all frequencies. It is impressive.

    Spurs on the other hand were where the 962 stuttered. The specs state non-harmonic spurs would be -70dBc below 10MHz. Well, not quite. Early on I noticed three pairs of sidebands with the scope's FFT. The first pair were +/- 710kHz of the fundamental. The next 2 pairs were harmonics of the first pair. I thought these might be from the switching power supply used, so I changed to a bench linear power supply. The sidebands remained unchanged. They appear to not be amplitude dependent. The db ratio stayed the same for a 100mVp-p output to a 4 Vp-p output.

    From 1MHz to 8MHz, these spurs were -65dBc. From 9MHz to 19MHz they were -60dBc. From 20MHz to 27MHz they were -55dBc. From 28MHz to 40MHz they were -50dBc. From 41MHz to 49MHz they were -45dBc. From 50 to 60MHz the level was around -40dBc. Also, from 54MHz to 60MHz, there were uncorrelated spurs at 10MHz and 20 MHz above the fundamental. These were around -60dBc. Those sidebands look like something is frequency modulating the output.
    Maybe someone who is more of a DDS expert might shed some light in a future review.

    The good news for me is that the spurs are down far enough in my frequency range of interest to not be a problem.

    I do want to mention the internal AM and FM functions. These worked perfectly. On the spectrum analyzer, the levels were almost textbook.
    Most of my testing was 1 MHz and above, but I did do some amplitude and frequency checks from 50Hz to 500kHz. Again, the levels were accurate and stable. Frequency also was accurate and stable.

    I did a check of THD for the audio range and measured a value of 0.02% - which is pretty good for this type of generator. Also, the linear and logarithmic sweeps work as they should with good amplitude stability.

    The two outputs can be synchronized with each other. This works really well. It's easy to see on the scope and using two 2.5Vp-p signals and the scope's ADD function yielded a nice 5Vp-p signal. Another way is via Lissajous patterns. Setting the scope to X-Y mode and setting the generator for 2 identical signals yields the expected pattern. Twiddling around with the phase adjust on the generator allows an easy way to view the phase differences. Lissajous patterns don't look near as cool on a digital scope as they do on an old analog scope.

    I knocked a star off for the spurs and maybe a little to do with ergonomics. Having the ports on the side means you'll have cables wrapping around the back or front unless what you're working on can always be to the right. Adding an inch to the bottom and moving the BNCs to the front would be nice. Also, the ports are too close together.

    I did no tests regarding the Arb function or the software. If that's your area of interest, you might check out the EEVBlog website where a good discussion on programming options has been discussed. Using a Mini-Circuits mixer and both channels, you should be able to extend the range to 120MHz - maybe not the cleanest output, but still useable for some things. It's next on my list.

    I've been updating this review over the last month when I had time to complete my tests. I see now the generator has become "Unavailable". That's really unfortunate as it is one of the best I've seen in this price range.

    The media could not be loaded.
    I was looking for a Function Generator that doesn't cost me an arm and a leg, while providing sufficient functionality for a hobbyist. I decided to buy this one, even though it's in the lower price range. After watching reviews on YouTube, I was confident that I would like it.

    Once it was on my table, I was really impressed. It's nicely built and the screen is brilliant. The signals are smooth and have less noise than my Oscilloscope which has a noise floor of some 300 uV RMS. I can't tell any difference in the noise level, when I connect the UTG962E. One thing that I particularly appreciate is the DC output (also with less noise than I can measure), which has far less noise than my switching power supplies (of course with limited current).

    Square wave rise time is 15 ns as specified, which is good enough (if I need steeper slopes, I can always run it through a SN74AC15 to get 2.5 ns rise time).

    I tested the Frequency counter (under Utility) against a PPS (Pulse Per Second) signal from a GPS and it turned out, that the time base of the UTG is only 1.7ppm off. This is better than my oscilloscope.

    The user interface is very intuitive and flexible. Very easy to change from "Amplitude and Offset" to "Low and High", from Frequency to Period, etc. Well thought out.

    I only have one point that I find a bit unfortunate: When changing parameters, the output looses it's phase.
    It's not a problem, when both outputs are Phase locked and one of the output is used to change phase. That works fine. However, if I want to compare the UTG output against another source with a similar frequency, it is a random number game to set the phase relationship between the two sources (like a 1 Hz signal from the UTG against a 1 Hz PPS from a reference). But this is a small thing. That's why I still give it 5 stars.

    All in all. It is far more that I expected and I need for my hobby, where ppm level is good enough.

    The movie shows the 1PPS from the GPS (yellow, used to trigger) against a sine wave with set frequency on the UTG of 1.00000179 MHz (cyan). There is very little jitter. (It also shows, how the phase jumps, when a parameter is changed).
    The picture shows the Frequency measurement of the 1PPS signal from the GPS. Done this for a few days now, it is constantly around 1.7 ppm off.

    Es muy pequeño y practico estoy muy satisfecho con mi compra, el generador de funciones funciona a la perfección. Aunque debería agregar una segunda punta Bnc ya que tiene 2 canales de salida.
