RF input
Two 3.5
mm input connectors, only used in high frequency mode:
●
RF IN receives the RF source signal from the diplexer. A semi-rigid cable con-
nects RF IN to the RF HIGH OUT connector on the top side of the diplexer.
●
LO IN receives the local oscillator signal from the R&S
ZNA67 network ana-
lyzer.
The complete RF connection of the external test set is described in
"Connecting the external test sets"
Risk of instrument damage
The RF input power at the connectors RF IN and LO IN must not exceed
the maximum values quoted in the data sheet. The maximum values are
below the maximum RF source power of the network analyzer. The
"ZNA67EXT-TS" converter type configuration ensures compatible source
powers.
Before you connect your external test set to the network analyzer, always
select the "ZNA67EXT-TS" converter type for the respective converter port
in the "Frequency Converter" dialog (see
