Title: 6254BD reduces measured V if Time/DIV < 500ns [Print this page] Author: mtino Time: 2023-4-12 08:05 Title: 6254BD reduces measured V if Time/DIV < 500ns Edited by mtino at 2023-4-22 07:39
Hello,
I recently acquired a 6254BD USB scope.
The issue I have is when I select a Time/DIV smaller than 500ns, the measured voltage is reduced. For instance if a 5.0V is at the input, if 200ns is selected, the voltage reported is 4.2V!!!
It is supposed this version is up to 250MHZ I was not expecting to have this big accuracy error.
Please provide a fix to use it properly.
I want to measure a clock signal rise/ fall time, with the reduced value of the TOP voltage, I do not know how accurate is the gotten results.
BTW, what levels for rise/fall time are used? 20/80 , 10/90?
Thanks in advance for your support
