UNI-T UTG932 Function Generator Arbitrary Waveform 30 MHz Dual-Channel 200MSa/s 14 Bits Frequency Meter with USA Power Adapter USB Cable Power Cord BNC Cable Alligator Clips

As a first point, let me say that this is an excellent 60 MHz generator for only Numerous generators made by different Chinese companies are similar in design. There is a good chance that all of them have the same main board system. I have used one of these a few years ago - I found it to be a good experience. It's the Koolertron GH-100 There are two CJDS2s, one of which is comparable to the UNI-S Also, it was a 60MHz generator, but I returned it because of issues with output stability and spectral purity. A lot of these companies specialize in making goods from small parts of China, and their quality is hit and With more reviews forthcoming, it will probably be confirmed that the same is true for this generator. In general,
UNI- A full manual for the 962 as well as software for the arbitrary waveform function are available on Trends' website. The manual covers the operation of the generator thoroughly and I recommend that you make use of it. You should pay attention to the specifications so you know what it can and cannot In comparison to a full size bench generator such as the ones available from Siglent or Rigol, there are some limitations at this price point. You should consider the specifications in light of what you intend to use the device for. To me, a small generator that I can move easily as needed would be perfect for my use in the HF frequency range, particularly RF sinewaves. I have reflected my opinions on this application in this review. As a result of testing it thoroughly, I was confident that the 962 To evaluate the unit, I used the following criteria. - Teledyne - The Lecroy Wavesurfer 500MHz scope is coupled with a Siglent 3032 Spectrum Analyzer. Keithley 2015 6x6 digital meter. DMM with 5 digits and THD meter Br>TTI TF The 930 frequency counter has a 10 digit frequency scale, and a GPSDO timebase
Finite Convergence Power Management Circuits The first time I ran the power meter I used a 6000RC Both channels are operating at 2 Vp-H for 100 hours while 962 is broadcasted The input to the 50 Ohm load is 10MHz. The following measurements were carried out after a 60 minute warm-up Getting the test equipment and the 962 generator ready for use. I would like to mention at this point that the 962 offers a choice of output impedance, and includes continuous adjustment between 10 ohms and 1000 ohms. In my case, this is a crucial feature since I primarily use 50 Ohms and 600 Ohms occasionally. Although I have not yet measured the output impedance, I am confident that it is almost exactly 50 Ohms based on my other tests. If you use a 50 Ohm output Z, you will be limited to the output amplitude of 5 volts. Since I usually use levels well below that level, this is not an issue for me. The output amplitude accuracy is the next topic. The movie is excellent, to put it simply. It consistently measured within 1% of the target on Channel 1 and across a number of frequencies and output levels. About 5% of Channel Two's ad revenue comes from its advertising. The amplitude of both channels was also stable for a period of an hour or more, varying usually by less than a few microvolts. The measurements are from 63mVp to 68mVp The following are p-4. This is p over a multiple of For a piece of gear in this price range, the frequency accuracy and stability were remarkable. In this case, there were only a few variations. If you are working at 50kHz to 60MHz, keep the jitter to 5ppm or less. According to the specs, there should be a A 50ppm value is regarded as ideal. That means maybe I found one that's really good. This is the spectral purity of the signal. The problem with inexpensive generators is that they fall short here. Despite its flaws, the 962 is still a useful car. Harmonics are required to be at least - and minimally - at the fundamental output, as per specs. There is a 40dB reduction between 30MHz and Harmonics generally range from - to Every frequency should be equal to or better than 60dB down. This is an impressive build. Spurs, on the other hand, were where the 962 faltered. There is no mention of this in the specifications In harmonics, the spurs would be these The low end of this range is 70dBc. However, I noticed three pairs of sidebands with the FFT of the scope shortly after it was installed. There was a +/- difference between the first pair There is a fundamental frequency of 710kHz. There were 2 pairs after the first pair, which were harmonics. It occurred to me that these might be caused by the switching power supply I was using, so I changed it Neither the sidebands nor the collar have changed. The amplitude does not seem to be a factor. In the 100mVp-500mVp test, the db ratio did not change The P output goes to a 4 Vp-style power supply It is output by p. These spurs were at 1MHz to 8MHz, and between those two frequencies they decreased to 0% From 9MHz to 19MHz, they were -65dBc Between 20MHz and 27MHz, the signals were -60dBc At 28MHz, they were 55dBc at 40MHz, they were -65dBc The difference in dBc from 41MHz to 49MHz was -50dBc The level from 50 to 60MHz was approximately 45dBc, and from 70 to 80MHz was around -90dBc. From 54MHz to 60MHz, there were two uncorrelated spurs at 10MHz and 20 MHz above the fundamental as well. The following items were around at the time It looks like there is a frequency modulation involved in the output, as those sidebands are 60dBc. We might be able to get some information about DDS from someone who has more expertise in the field. It is a good thing for me that the spurs are down below my range of interest, so I don't have to worry about them. In addition to the FM and AM internal functions, I want to mention the clock that is built into the unit. I was able to use these without a problem. I almost used a textbook spectrum analyzer to check the levels. It seems that most of my testing was between 1 MHz and 2 MHz, but I did do some amplitude and frequency checks between 50Hz and I found the levels to be accurate and stable again. As well as accuracy and stability, frequency was excellent. My THD measurement for the audio range was 0. I verified this with the audio range and it was The following are the 02% decrease results The generator has an efficiency of about 60%, which is pretty good for this type of unit. There is also good stability in amplitude with the linear and logarithmic sweeps. In order to synchronize the outputs, their outputs must be on the same channel. I really like how this works. Using two 2's and scopes, it's very easy to see what's going on. Five volts plus By combining the p signals and the ADD function, I was able to get a nice 5Vp-- There is a p-signal. As another alternative, Lissajous patterns can be used. A scope of X-rays can be set If you set the generator for 2 identical signals in Y mode, the expected pattern will appear. When the phase adjust on the generator is turned on, it is easy to see whether two phases are the same. It's not nearly as cool to see a Lissajous pattern on a digital scope as it is on an analog one. I knocked off a star for the spurs, and maybe a little because there was an issue The ports being on the side will mean that you will have cables wrapping around the front or back of the computer unless what you are working on is always The bottom of the connectors is too narrow and the BNCs should be shifted to the front. Furthermore, there is too close spacing between the ports. There were no tests done for the Arb function or the software on my end. you are interested in programming options, you should check out the EEVBlog, where there has been a good discussion on the subject. Making use of the mini-computer In the case of a circuit mixer and both channels, you may be able to extend the range up to 120MHz. The results may not be as clean as they could be, but they can still be useful for some purposes. I've been reviewing this over the past month when I had time to complete my tests.

My work requires precision, so it's fine for me. Aligning and tuning CB radios is what I do with it. It is a great way to modulate AM. There will be a level difference between the signal and the CB level, so you'll need an attenuator. It's a pretty good tool all in all.

My understanding of the instrument may need to be further enhanced by observing more of its features. The first test of this product shows that it's well made and is.
