jknightandkarr Posted March 23, 2016 Report Share Posted March 23, 2016 (edited) Ok just to make sure i am doing this right on my Instek GOS-620 scope.Volts= No divisions × volts/div x probe settingMy case v= 2.0 x 0.1 x 10 so v=2. Now freq is #of div/cycle × time/div i have t=6.6 x 50us=330us n freq=1/t or 1/330= 3.03 kHz buuuut the signal is the scopes 1kHz, 2Vp-p signal and my multifunction counter says1.04 kHz, so what am i doing wrong? I know having the counter i don't have to know how to calculate it but nice to know how. ThanksJoe Edited March 23, 2016 by jknightandkarr Quote Link to comment Share on other sites More sharing options...

pebe Posted March 30, 2016 Report Share Posted March 30, 2016 According to the manual, there is a control marked 'SWP.VAR' (marked 30 in the diagram that shows layout of controls) that allows the sweep to be made variable. Have you set it correctly?. Quote Link to comment Share on other sites More sharing options...
