Hi everybody,
I recently got hold of a Hameg HM8131-2 DDS function generator.
Apart from a hypersensitive encoder and a little DC offset, it seems to be working fine.
Any idea on how to obtain a service manual for this thing? I already checked the obvious resources (Rohde-Schwarz website, elektrotanya, ko4bb, this forum, general Google search) but found nothing except the user manual, which does not include schematics or a calibration procedure.
Is there somebody here with experience with the device, who can tell me what the individual trimpots and jumpers are good for? I would really like to work based on some guidance before I screwdriver the function generator :-(
