UTG932E Arbitrary Waveform Generator Function

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!...

Works great and ez to use and setup. Very well made. Software is a bit difficult to understand as the manual isn’t particularly well written. But the hardware works fine. Worth while investment.

Why did you pick this product vs others?: The generator is unreliable and eventually stops working. Mine stopped functioning after just eight months. Customer service is poor, and the seller does not stand behind the product. I would not purchase this again.

This one really surprised me. I've had a professional signal generator before, and for the life of me I cannot tell what this cheapie one cannot do that the other one can. I use this mostly to test transistor response and tune filters. Sine wave is useable all the way up to about 25MHz. Square wave or other complex waves are useable up to maybe 2-3MHz. Which will completely cover your I2C needs, but maybe not SPI. Oh and it has two channels. So you can test mixers and amps. Absolutely insane value for the price.

So far it seems great for our purposes, but we have not got to the hard stuff yet, testing the opamps configuration for control voltage inputs. Will update once we do that. In the meantime, really like the small size and large screen. Only complaint is that it can't save our arbitrary waveforms through a power cycle, but that wasn't worth paying more money to get at this point.

Muy bueno!!!

This thing is awesome for the price. I have a more expensive BK Precision signal generator that doesn't even go lower than 20% duty cycle. What the heck!?! This thing is smaller and has more features than signal generators twice the price. Well worth the purchase.

Pros: - It looks like a cute little scope. - Sits up or on its back. - Solid physical build. Cons: - Tons of noise on the output from the internal switching supply, like 80mVpp. - Waveform glitches when you change the frequency, amplitude, offset, or phase. - I/O on sides rather than front is problematic in a fixed bench setup. - User interface takes some effort to get used to. General: All I needed was a relatively clean, stable, low voltage sine wave source that could go to a couple of MHz, and on paper this unit should have been overkill. But it's a glitch monster when changing anything associated with the output. The internal switching supply is the real killer though, the random noise it introduces makes even scope triggering problematic. I didn't sufficiently test this unit when it arrived, and now it's outside of the return window.
