 A click in one of the boxes in the list of calibrations in the upper left part of the dialog starts the
calibration sweeps for the RF source, IF source or receiver, and the LO source, respectively. The
measured power is shown in the diagram to the right and the sweep progress in the message field
below.
The list of calibrations depends on the correction type selected in the Define Scalar Mixer
Measurement dialog; see background information above.
If a calibration cannot be performed using the currently selected settings, the respective box is
marked with an exclamation mark and an error description is shown in the lower left part of the
dialog.
 Abort Sweep stops the current sweep, e.g. in order to change the sweep settings.
 The calibration sweeps are performed according to the settings shown in the Source/Receiver Cal
Settings panel below the list of calibrations. Modify Settings opens the Modify Source Power Cal
Settings dialog to modify the essential settings of the next calibration sweep.
 Power Meter selects an external power meter that is used to measure the exact source power at
the calibration plane; see Power Meter Settings in the Power Calibration section. Power meters
(Pmtr1, Pmtr2, ...) must be configured in the System Configuration – External Power Meters
dialog before they appear in the list.
 Perform Verification Sweep after Cal enables or disables a verification sweep that the analyzer
performs after each 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.
The calibration sweeps for the different power calibration steps can be viewed in remote control, too.
See Viewing calibration sweeps in remote state.
