As a convenience, you can specify the load impedance as seen by the
function generator and thereby display the correct load voltage. If the actual
load impedance is different than the value specified, the displayed
amplitude, offset, and high/low levels will be incorrect. Variations in source
resistance are measured and taken into account during an instrument
calibration. Therefore, the accuracy of the load voltage depends primarily on
the accuracy of the load resistance as shown below.
