I am having problems with the ADC-100 that I purchased a couple of weeks ago. I just hooked it up to a function generator to see how it works. I had my function generator set at a square wave running at 1kHz with 500mVpp. When I look at the signal with the oscilloscope, it shows me a 1kHz with about 10mV peak to peak. I then changed to a sine wave running at 1kHz with 500mVpp, and the scope showed a 1kHz square wave at 10mV peak to peak.
I have verified that the output of the function generator works with a known good oscilloscope. I can vary the frequency on the function generator, and the frequency on the pico scope varies just fine. The problem is when I vary the amplitude, the amplitude of the pico scope does not vary at all. It is stuck on 5mVpp.
Any help would be greatly appreciated.
