Hi,
I have a GW Function Generator model GFG-8016D that isn't working properly. Basically, the OUTPUT port is always about -14VDC, and adjusting the frequency or other controls doesn't change the output at all (there's no AC waveform present). The only one that makes a difference is pulling the AMPL knob out (for -20dB) does bring the output down to about -1.2VDC. The frequency generation seems to be working though, since the TTL/CMOS output does work correctly with perfect control. So, it seems like there's something wrong with just the function output section.
Unfortunately, I haven't been able to locate schematics, or even really any repair info on this. Does anyone have the schematics, or know anything about this model (does it have any clones that do have repair info), or in general know what is likely the problem (from similar problems on other frequency generators)?
Thanks, Pat
