The Receiver Power Cal dialog provides the following control elements:
 Wave Quantity to Calibrate provides two pull-down lists to select one of the transmitted waves a
n
or one of the received waves b
n
for the calibration. Each power calibration only applies to the
selected wave quantity in the active measurement.
 Receiver Power Correction Off can be selected/deselected as soon as power calibration data has
been acquired for the active wave quantity. If the box is checked, the calibration data is kept in
memory but not applied to the wave quantity. The Power Correction Off softkey disables the
power correction for all receivers and sources.
 Calibration Source contains all analyzer ports or external generators which can which can be used
as a source for the calibrated wave quantity. The list contains all analyzer ports Port 1 to Port n.
Generators (Gen 1, Gen 2 ...) must be configured explicitly in the System Configuration – External
Generators dialog before they appear in the list.
Beneath the selected source, a label displays the current status of the selected source's Flatness
and/or Reference Rcvr power calibration (if available)
See Power Calibration State Labels for the possible states.
 If an analyzer port (Port 1 ...) is selected as a Calibration Source, the Reference Power Value for
the receiver calibration can be selected in addition. The Reference Receiver values are potentially
more accurate, provided that an accurate source power calibration including a reference receiver
calibration is available (Channel – Calibration – Start Power Cal – Source Power Cal... – Modify
Settings – Reference Receiver Cal: On). Alternatively, you can use the (factory-calibrated)
nominal source power levels.
 Take Cal Sweep initiates a calibration sweep for the selected wave quantity and source. The
progress of the sweep is monitored in the Sweep progress bar.
 Abort Sweep stops a running sweep. The data acquired in the aborted sweep is discarded.
The accuracy of the receiver power calibration depends on the accuracy of the source. Depending on
the test setup and reference plane, it is recommendable to perform a source power calibration before the
receiver power calibration.
