Signal Path Compensation
To optimize measurement accuracy, see the oscilloscope online help to perform the instrument signal path compensation
procedure. Use the procedure if the temperature has changed more than 5 °C since the last signal path compensation.
Perform the signal path compensation once a week. Failure to do so may result in the instrument not meeting warranted
performance levels at those volts/div settings.
