As shown below, the 33210A has a fixed series output impedance of 50
Ω
,
forming a voltage divider with the load resistance.
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.
