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.
