In Spectrum mode or any other application (R&S ZNL only), Port 2 is used as RF
INPUT 50 Ohm .
Port 1 is used to provide an independant CW output signal, if option R&S ZNL/ZNLE-
K14 is installed and active.
4.2.1.9 RF INPUT 50 Ohm
Provides RF input from a connected device under test (DUT) to the R&S ZNL, 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. Do not overload the
input. For maximum allowed values, see the data sheet.
For the R&S ZNLE, the Spectrum mode is not available and hence this connector is
always used as VNA port 2.
See also Chapter 4.1.13, "Considerations for test setup" , on page 37.
