I am using the automotive pico kit (ADC-212). When viewing signals with a time base of 200ms/div or more my waveforms become distorted. Today i was looking at a square wave signal on a single trace that was no more than 4 or 5hz. On a 100ms/div (1 second total screen) time base the signal looks perfect. If I increase the time base to 200ms/div the square wave starts to look like triangles with lots of distortion. I am somewhat familiar with record points and scope limitations, but i could use some help.
The first time I had this problem was performing a relative compression test with time base and current levels being set up automatically by the scope. Only after dropping the time per/div (the automatic setting is 200ms/div) was i able to see clean starter current "humps".
This has been a problem for me since day 1 and I have just now recognized the pattern for the problem.
Thanks in advance!!!
