a Set the precision source to provide a DC offset voltage at the Channel 1
output.
Note: Set the Low Force terminal of the Precision Source to its "Floating"
state to prevent offset error caused by ground loop current from the
Precision Source ground to the DUT ground.
b Use the multimeter to monitor the precision source DC output voltage.
