5.2.1.8
Port 1 and Port 2
Numbered type N female connectors.
The test ports serve as outputs for the RF stimulus signal and as inputs for the mea-
sured RF signals from the DUT (response signals).
●
With a single test port, it is possible to generate a stimulus signal and measure the
response signal in reflection. For a measurement example refer to
"Reflection S-Parameter Measurement"
●
With 2 test ports, it is possible to perform full two-port measurements; see
Maximum input levels
The maximum input levels at all test ports according to the front panel labeling 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.
In Spectrum mode or any other application (R&S
ZNL only), Port 2 is used as
.
5.2.1.9
RF INPUT 50
Ω
Connect a device under test (DUT) to the R&S
ZNL to provide RF input which is then
analyzed in an RF measurement. Connect the DUT to the "RF Input" on the R&S
ZNL
via a cable equipped with an appropriate connector.
For the R&S
ZNLE the Spectrum mode is not available and hence this connector is
always used as VNA Port 2.
