1Hz-500kHz DDS Signal Generator with Schumann Resonator, Portable Multifunction Waveform Generator with AC/DC Power, Ideal for Oscilloscope Calibration, Audio Testing, and Stress Relief

I had purchased this little signal generator to check out my Ham radio roof antenna. I never thought to use it to replace my big old signal generator in my ham shack. I was taking an advanced electronics course at a local college, and was using my old signal generator for class projects. Then my old signal generator bite the dust! So, I pulled out this pocket signal generator and presto, I was in business again! Great pocket device, my only complaint is that the instructions need to be better. You must push the Run button to generate any signal. For the little money I spent on this generator it was worth every penny. The signals were clear until the very high frequencies. The little thing fits in a large work pocket, and I intend to take it up on my roof to check on my Ham radio antenna.

Great value and arrived on time

Works ok for $36. The sine and triangle waves are the cleanest outputs. The other waveforms have some distortion in their output using my digital 12-bit scope, but it's a $36 non-professional waveform generator... Waveform frequency is very accurate. I am surprised how well it worked for the price paid. For home use, it serves it's purpose.

Not sure about accuracy, build quality is cheap, overly large and cables types are ancient (bnc connector). However, it does hav different wave types and does function as described.

This product works great. Good clean wave forms and uses a standard USB charger for power.

The media could not be loaded. You get what you pay for.

Seems to work as advertised, I bought it for audio use

I'm still learning how to use it but so far it's worked great.
