Source Gen
Defines the behavior of the RF signal source at the related port.
●
If unchecked (default), it is only switched on for the partial measurements that
require the port as a drive port.
●
If checked, it is switched on for all partial measurements (permanent signal
source).
"Source Gen" has no effect, if
is checked.
Switching on the signal source permanently eliminates the power settling times of the
DUT but can introduce measurement inaccuracies, e.g. due to crosstalk between two
ports. Therefore, "Source Gen" must be switched off to perform a system error correc-
tion.
Note:
Among the analyzer ports driven by the same
operate as generator port.
An
external generator
always represents a permanent signal source that is switched
on for all partial measurements. "Source Gen" determines whether the generator is
available as a signal source in the test setup. The analyzer provides two alternative,
independent ways of selecting a generator as a signal source:
●
Check "Source Gen" in the "Port Settings" dialog, especially if the generator is not
assigned to a particular measurement result or drive port.
●
Select the generator as a source for a particular measurement result or for a power
calibration, see e.g.

Freq. Conversion
Opens a dialog to define a port-specific stimulus frequency range (for frequency
sweeps) or CW frequency (for power, time and CW mode sweeps); see
on page 520. In the default configuration, the channel
base frequency f
b
is used.
This cell is only enabled, if the analyzer is equipped with option R&S
ZNA-K4. For fre-
quency converter ports (with option R&S
ZNA-K8), the formulas for the RF IN and "LO
IN" components are derived from the converter settings and hence are read-only.
The result is displayed in the "Frequency Result" column. A red "Freq. Conversion" cell
indicates that certain hardware limits are exceeded.

Receiver Freq.
This cell is only enabled, if the analyzer is equipped with option R&S
ZNA-K4. It
defines the frequencies to which the receivers are set while this port is the source port.
"Src. Freq."
Both receivers use the source formula (see
