 For an R&S ZVA110 system with external test sets, Port 1 and Port 2 denote the external
diplexer ports.
 Generators (Gen 1, Gen 2 ...) must be configured explicitly in the System Configuration –
External Generators dialog before they appear in the list.
 Frequency converters (Conv 1, Conv 2 ...) must be configured in the System
Configuration – Frequency Converters dialog.
Only frequency converters with electronic attenuators (R&S ZVA-ZxxxE) can be power-
calibrated. Furthermore, the Power Control method of the related port must be set to
Electronic Attenuator only.
 Set as Stimulus Axis causes the channel line of the active channel to show the (target) power of
the calibrated source port instead of the channel base power (e.g. Port 1 Pwr 0 dBm instead of
Base Pwr 0 dBm). This is particularly useful if the source port power levels differ from each other
and from the channel base power. For power sweeps, the original stimulus axis range is replaced
by the target power range of the calibrated port. After the calibration, the selected stimulus axis is
maintained and shows the calibrated source power at the reference plane.
Use the context menu of the channel line or the Channel – Mode – Port Configuration – Stimulus
dialog to select an arbitrary stimulus axis.
 Take Cal Sweep initiates a calibration sweep for the selected source. The progress of the sweep
is monitored in the calibration sweep diagram. After the necessary calibrations have been
completed, a message in the trace list indicates the status of the power calibration.
 Abort Sweep stops a running sweep. The data acquired in the aborted sweep is discarded.
 The Settings panel displays the essential parameters of the source power calibration, to be
defined in the Modify Source Power Cal Settings dialog.
 Source Power Correction Off can be selected/deselected as soon as power calibration data has
been acquired for the selected source. If the box is checked, the calibration data is kept in
memory but not applied to the source. The Power Correction Off softkey disables the power
correction for all receivers and sources.
 Modify Settings... opens the Modify Source Power Cal Settings dialog.
 Power Meter selects an external power meter that is used to measure the exact source power at
the calibration point. Power meters (Pmtr1, Pmtr2, ...) must be configured in the System
Configuration External Power Meters dialog before they appear in the list. The buttons in the
Power Meter panel provide settings for the selected power meter; see Power Meter Settings
below.
 Perform Verification Sweep after Cal enables or disables a verification sweep that the analyzer
performs after the source power calibration. The sweep is also displayed in the calibration sweep
diagram. Its purpose is to test the accuracy of the source power calibration after the final
correction data has been acquired. The final power calibration results are applied starting with the
first sweep after the verification sweep.
