Hi,
I've been looking (without success) for a service manual or schematics for a Systron-Donner / Datapulse 400 Function Generator.
If anyone has these or could scan at least the sine-shaping circuit (which in mine has gone faulty) or point me in the right direction of where I could obtain this information I'd be most grateful.
Thanks in advance,
