Hi all,
Earlier this year I acquired a vintage Philips PM3320A DSO and got some probes and after much fiddling decided that it was a bit faulty as it wasn't able to measure DC voltages at all, and even the voltages of signals seemed suspect. I eventually decided that it was an expensive write-off and got a Rigol DS1102E after discovering this blog (maybe Dave should buy a shipping container of them and re-sell them to people here?).
Anyway, I just noticed that the probes I bought for the Philips are 100x. Sure enough, using the Rigol probes at 1x I can measure DC voltages perfectly. So, does anyone know if it's possible to set attenuation on this particular Philips scope, or on similar Philips scopes? I've dug around the menus and can't see a setting, and don't have the user manual for it.
Cheers, Joel
