Signal Path Compensation
Signal Path Compensation (SPC) corrects for DC inaccuracies caused by temperature variations and/or long-term drift.
You should run the SPC whenever the ambient temperature has changed by more than 10 °C or once a week if you
use vertical settings of 5 mV per division or less. Failure to do so may result in the oscilloscope not meeting warranted
performance levels at those volts per division settings.
To compensate the signal path:
1. Warm up the oscilloscope for at least
20 minutes. Remove all input signals
(probes and cables) from channel inputs.
Input signals with AC components adversely
affect SPC.
2. Push Utility.
3. Push Utility Page.
