Re: Repairing my Tektronix 454 oscilloscope need some advice

 

Thank you Jim!

I need to be more careful with my postings and avoid dumb mistakes! I try not to think that it is the years...

The period of a 50 kHz wave is 20 uS, not 20mS. So this period is still 200 times longer than Trr. And in Trr = 100nS, the wave has not significantly receded from its peak, so the capacitor will not be significantly discharged during this time.

Ernesto
