Hello,
I've got an old scope C1-64 (http://www.cqham.ru/hpa/osc_c1-64.htm). And try see signal from my PC (let's say 1kHz). The scope only shows signal when + wire (phase wire) is connected to the source of the signal (to the middle pin of the RCA plug). When I connect ground ofthis plug, the signal in the screen dissapears and shows only ground line. Is it related to the settings I use? Or maybe ground isn't nessesary at all?
My settings are:

(Everything in Russian, but experienced specialist I hope understand)
Thanks in advance
