This connector is provided by the "Additional Interfaces" option R&S
FPL1-B5.
This option is not available for the R&S
ZNLE.

The IF/Video Output interface is only functional in Spectrum mode (option

ZNL3|4|6-B1)
●
Interruptions in analog output can occur if you switch between a VNA and a spec-
trum application, due to the separate hardware. In particular, if you run a sequence
of measurements including both measurement types, switching between both
modes can interrupt the signal from the output connector.

ZNL/ZNLE Spectrum Mode user manual.
