Other analyzer configurations
If you use an external combiner but no options R&S ZVA<frequency>-B16, you can still measure the
intermodulation products at the output of the DUT.
With an R&S ZVT20 network analyzer that is equipped with option R&S ZVT-B11, you can combine the
two source signals internally without using the SOURCE IN/OUT connectors and an external combiner.
You can also replace the external combiner by an Extension Unit R&S ZVAX24 or R&S ZVAX-TRM with
installed combiner option.
Intermodulation measurement, results
The intermodulation measurement provides two different types of results.
1. In the swept measurement, the analyzer performs a frequency or power sweep of the two-tone stimulus
signal and displays the selected intermodulation quantities as a function of the lower-tone frequency or
power.
2. In the intermodulation distortion spectrum measurement, the frequency and power of the lower and
upper tones are kept constant; the analyzer displays all intermodulation products in the vicinity of these
signals up to a selectable order.
