Example 5 - Making a Difference Measurement
The following program segment can be carried out on the N1912A. It queries the
lower window to make a difference measurement of Channel A -Channel B. The
expected power level and resolution parameters are defaulted, leaving them at
their current settings. Some fine tuning of the measurement is carried out by
setting the averaging, and the trigger delay to off.
