Professional Upgraded 15MHz DDS Signal Generator Counter, Seesii 2.4Inch LCD Display High Precision 200MSa/s Dual-Channel Arbitrary Waveform FG-615 Function Generator Frequency Meter

This is a great signal generator. It certainly works well for my purpose, testing audio circuits in amplifiers.

I have bought a ton of these over the years for special projects, and they are very dependable. Only once did I get one where the power adapter didn't work. Highly recommended

We were looking to generate a single cycle of sinewave (with adjustable period and amplitude) when triggered by an external logic pulse. This did the job perfectly.

Great product, works as it should. Nice display and options. See pictures.

I thought this would be a nice little addition to my bench. I was wrong. First off, it's extremely lightweight and slides around at the slightest touch. Second, and most importantly, it's wildly inaccurate. I double checked it against my Rigol scope. 5khz sine @ 2v attentuation. While the frequency was accurate the voltage swung from 1.2 to 2.2 volts. At 500mV, my scope could barely lock on to it, that's how bad it is. It's useless for any work where you need precision. Avoid.

broke after about about a month of use and upon opening it, they laser removed all the IC names so that you cannot fix it. They also did not provide a schematic to fix it either if you won’t let me fix a product at least make it so it doesn’t break.

I only needed an audio generator to test my hearing aids and to setup my graphic equalizer. This turned out to be more than I needed. It is well built and easy to operate. I went thru several of the menus and will probably use many of them. I am very satisfied and would certainly purchase it again.

Well thought out user interface. Especially the ability to change frequency with rotary adjustment, with sensitivity of the adjustment set by selecting the appropriate digit to adjust. Highly recommend for basic function generator.
