[vehiculeselectriques]

Hello,

I have an old GFG-8019G function generator i would be happy to use again but it indicate 0000 Hz on LCD though gate led is blinking with frequency range selection.
Connecting it to oscilloscope confirm there is nothing at output





first time for me do you have some experience on where to look please ?

if it can help here or to someone one day i include 8019G manual and 8016G manual.

i'm studying schematics 8016G manual as both models seem very similar


thanks for your help

the counter can be internal or external

for the signal path  please read the manual  gfg-8019g  .....      you have good descriptions, down to the output amplifier section,
you have everything in theses lines / explanations how to do diagnostics


usual checks :  supply lines,   you have many voltages
