Re: FG085 - Static Waveform Output
I did a visual inspection under magnification of the board and did not find any issues. I did complete the DSO-038 Oscilliscope kit and again tested the output of the FG with a square wave - I have attached an image of the results. DSC_0501 (2).JPG I think I need a replacement - please let me know h...

Re: FG085 - Static Waveform Output
OK, I was working with my professor and a scope yesterday checking various circuits against the schematic. We took the output signal directly off the board with no change. Tracing back the circuits the problem appears to be with either U3 or U13. The FG was set to a 10Khz Sine Wave and the input to ...

Re: FG085 - Static Waveform Output
I tested the FG085 via the BNC connector on the front panel. I used a BNC-BNC cable directly connected between the FG and the scope.
I don't recall the amplitude but was using .1 V/ div - if that helps at all. I don't always have immediate access to an Oscilloscope.
Thanks,

FG085 - Static Waveform Output
I just finished building my FG085 and carefully followed the instructions and double checked solder connections and polarity. Initially upon powering up with included power supply I got only a blinking LCD backlight - no text or functionality from the device. After reading some of the threads I trie...
