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.
Remote command:
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate]:OFFSet

Port Power Offset
Defines a port-specific offset to the Channel Base Power The actual output power at
the port is equal to the "Channel Base Power" plus the "Port Power Offset".
If P
b
is selected as "Channel Base Power", then for a power sweep the actual port
power varies across the sweep. Otherwise the port power is constant.
