Example 6 - Making a Ratio Measurement
The following program segment can be carried out on the HP E4419B. It
queries the lower window to make a ratio measurement of channel A/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.
