The test ports serve as outputs for the RF stimulus signal and as inputs for the
measured RF signals from the DUT (response signals).
●
With a single test port, it is possible to generate a stimulus signal and mea-
sure the response signal in reflection. For a measurement example, refer to
Chapter 5.1.2, "Reflection S-Parameter Measurement"
●
With 2 test ports, it is possible to perform full two-port measurements; see
Chapter 5.1.1, "Transmission S-Parameter Measurement"
Maximum input levels
The maximum input levels at all test ports according to the front panel label-
ing or the data sheet must not be exceeded.
In addition, the maximum input voltages of the other input connectors at the
rear panel must not be exceeded.
It is recommended that you use a torque wrench when screwing RF cables
on the test port connectors.
