Re: HP 3325A Function Generator A3 Mixer Troubleshooting U15 And R106


 

Ozan,

Finally got to the power supply to check ripple. The +15 is 29mV, the -15 is 15mV, and the +5 is 23mV. But the waveform at the +5 on the scope(ac coupled) is troublesome. The waveforms at both 15V looked pretty normal.
