The diagram in the center of the dialog visualizes the settings and results below.
Port Cal Power
Allows you to define (port-specific) power levels for source power calibrations.
Port Overview ← Port Cal Power
The dialog shows all source ports of the network analyzer. Each port is displayed with
the current "Power Result" at the input of the DUT (in dBm) and offset (i.e. the "Cal
Power Offet" in dB).
Configured external generators ("G1" ...) and the Converter LO are included in the
source port overview.
Remote command:
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate]:OFFSet
SOURce<Ch>:POWer<PhyPt>:CORRection:LEVel:OFFSet
Channel Base Power ← Port Cal 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
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.
