HP 8657B af generator problem
|
hi all! I'm looking for help for a problem with my 8657B.
AF generator is slightly low on 1khz (997hz) 400hz is perfect ! I cant find the adjustment in servicing manual.
I adjusted the oscillator to 0.707 vac. I can't find a way to calibrate my 1khz? thank you for your HELP AND HAVE A GOOD DAY
