Goupchn Programmable DDS Signal Generator 80MHz 3.5inch Screen Dual Channel | Arbitrary Waveform Function Generator, Frequency Meter 300MSa/s, Counter High Precision

Awesome for the Price

I already own a very nice HP signal generator, but it takes up half my work bench. I watched some people review this same generator and bitched about the voltage going up and down as you sweep the frequency. I marveled at their nice expensive scopes and other equipment but was dumbfounded how they did not know what they were doing while complaining about the voltage swings or how the square waves were not very square at 80 mHz. Duh....Folks, if you're going to do a video review - at least admit you don't know what you're really doing.Things to know to test this properly are:1) Use 50 Ohm coax to connect it to your scope.2) Make sure the end at the scope is terminated with a 50 ohm load resistor.3) Set a reasonable voltage, say 1 volt P-P.4) Set the output to a sine wave. Don't expect a square wave to look very square at 80 mHzNow you'll get a steady output all up and down with less than 3dB variation. In my case quite a bit less on one channel but slightly more on the other.For the money this is a great deal and you can modulate the output externally which is wonderful if you're and RF guy like I am.

I've the PSG9060 model over a year ago, and it is working great so far. I'm at the point of expanding my experience beyond the basic functionality. I cannot find the software required to program the generator. Can I get some help with this issue?

I've been using this signal generator for the past 6 months to test and calibrate radio, HiFi, and Stereo equipment. It does everything that generators costing hundreds more can do. One minor quibble: When using modulation, it would be great if it could stay on when switching to the main signal screen to adjust the frequency or level. It's inconvenient to lose modulation when trying to make those adjustments.

Glad I got this generator, very happy with it. As an old school retired industrial/radio station engineer, I had fun testing it's functions. PC software install was bug free. Frequency accuracy is excellent, after a 30 minute warm up. AC amplitude accuracy is also very good. When using the DC source, the output is about 10% high. Haven't tested the counter yet, but I'll bet it is accurate.

I have contacted Amazon and they agreed to exchange it. I hope this is not a recurring problem with this manufacturer. I will update this review if possible, or create another review for the exchanged item..

This unit has some nice features. However, the unit I received would not hold frequency. If I set it at 10.000MHz it would immediately start counting down (my frequency counter is an Agilent 53131A with a 10MHz Trimble GPSDO External oscillator). The unit would not update its firmware also. I contacted the manufacturer. They emailed me stating that they would forward my request to engineering. I have not heard from them again. I returned it and purchased a Rigol DG1022Z and it works great.

Ease of use, and specs. Retired my old Heathkit.
