Example 6 - Making a Ratio Measurement
The following program segment can be carried out on the N1912A. 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.
Using READ?
