Very small amplitude, purchased pre-assembled

Post by MattSouth »

I just picked one of these up pre-assembled from Amazon and I'm getting nice wave forms, except the amplitude is tiny. The amplitude does go up and down as I adjust the amplitude setting, but even at 10v amplitude I'm getting less than 1Vpp, even with no load (connected directly to the 1Mohm scope input). Behavior is the same for all wave forms. I attached a couple of pictures; a screen shot of the FG085 set to 10Vpp triangle wave, and the reading from my scope showing only 922mV peak-peak (no load). I haven't had time to debug it yet myself, but I'm hoping someone else has seen this before and can save me a little time by telling me what it might be.

I found the problem, it was my own stupid mistake. I was using 10x probes, but had my scope set to 1x. Changed the scope to 10x and presto all is fine.
