Arbitrary Power tab
Configures the source ports of the R&S ZNA for port-specific powers.
Channel base power
After a Reset, all source port powers are set to the channel base power P
b
. For power
sweeps, P
b
corresponds to the unmodified sweep range. For frequency, time, and CW
mode sweeps, it is equal to the fixed "Power". f
b
is defined by the "Stimulus" parame-
ters (see Chapter 5.8, "Stimulus softtool", on page 473).
Active frequency converter ports are displayed with their RF IN and LO IN compo-
nents.
Non-editable table columns
In addition to the test ports ("Port"), the source ports include all configured external
generators ("Source Gen"). Each port is displayed with its port number and device type
("Info").
For each port, the available power range and resulting port power are calculated from
the configured power conversion and source attenuation settings.
Channel Base Power
Allows you to select between the channel base power P
b
and a fixed value of 0 dBm.
If frequency converters are configured, the "Channel Base Power" at the RF IN port
can also show "varies", which either indicates that leveling data are used or that a
source flatness calibration at the converter port is active. In the former case, the
combo-box is disabled. In the latter case, you can alternatively select P
b
or 0 dBm,
which deactivates the source flatness cal, or select "varies" to reactivate it.
