DSO SHELL Test - Incorrect Voltages from Test Signal

Post by acronomic »

Hi,

I am trying to calibrate my DSO Shell using the TS Amp signals, but my readings still seem to be very off. I am using a power supply at 9.2V. The voltages at the test points are off. Especially V+ and V- which are reading closer to 7.79 and -7.79, and AV+/- is 6.88 and -6.38

The .1V TS shows a Vmax of 42 mV and a Vrms of 28mV. The 3.3V TS shows a Vmax of .93V and a Vrms of .6V. Any help would be appreciated.

Thanks,

Michael
