IF/Video Output
The female BNC connector can be used for various outputs in the Spectrum applica-
tion:
●
Intermediate frequency (IF) output of approximately 20 MHz
●
Video output (1V)
Which output is provided is defined in the software ("Overview" > "Output" ).
●
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
R&S
ZNL3|6-B1)
●
Interruptions in analog output may 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.
For details, see the R&S
ZNL/ZNLE Spectrum Mode User Manual.
