:CALibration:IQ:FLATness:Q
Example CAL:IQ:FLAT:Q
Notes The recommended procedure is to use the same BNC cable to calibrate all I/Q ports. All I/Q ports
should be calibrated sequentially during the procedure.
The calibration data is saved as soon as the port is calibrated and will survive power cycles. It is not
reset by any preset or restore data commands.
Notes The Q port must be connected to the Cal Out port before issuing the SCPI command.
State Saved No
Initial S/W Revision Prior to A.02.00
Exit
Exit the calibration procedure. All ports calibrated before pressing Exit will use the newly acquired
calibration data.

Notes Using the Exit button will not restore the calibration data to the state prior to entering the guided
calibration. Once a port is calibrated the data is stored immediately and the only way to change it is
to redo the calibration step.
When the calibration may be left in an inconsistent state, a confirmation dialog will be displayed (see
"Exit Confirmation" on page 220 ).
Initial S/W Revision Prior to A.02.00
Q-bar Port
The Q-bar port calibration is performed with the front panel's Q-bar port connected via a short BNC cable
to the Cal Out port. The guided calibration will show a diagram of the required connections.
Back
Return to the prior step in the calibration procedure.

Notes Using the Back button will not restore the calibration data to a prior state. Once a port is calibrated
the data is stored immediately and the only way to change it is to redo the calibration step. The Back
button allows the user to go back to a prior step to redo that calibration step.
Initial S/W Revision Prior to A.02.00
Next
Perform the Q-bar port calibration.
