Hello,
Does any one have schematics or know the DC output voltage from the A21 board from a anritsu 69269A signal generator. The A21 board simply takes the AC line voltage /filters it and rectifies it. I am guessing that the DC voltage is simply line rectified. I want to be sure.. I need to spin a PCB to replace this board since I cannot find a replacement board from anritsu, ebay etc....

The part should be the same for the family of generators that are 692XXA types...

Appreciate it!!
Ravi

I believe the output is +160V and -160V, these go into the switching power supply A19.
