Saw tooth waveform looking good?

by jorrit on Sat Jun 03, 2017 2:11 pm

I am half way fabricating the VCO. In attachment you see the saw tooth waveform. Is this looking good or what could be wrong? I am asking because I am missing the vertical lines.

Kit bought at x0xsh0p.de, 3V source is watch battery, using this manual.

Thanks for any help.

that's fine

you won't see the vertical line on this CRT scope
it's a very short transition, so the beam has almost no time to leave a bright enough trace on the screen
