I/Q Cable Calibration Time (Remote Command Only)

Returns the last date and time that the I/Q Cable Calibration was performed for a specific port. This is a
remote query command only.

I/Q Probe Calibration
The I/Q probe calibration creates correction data for one of the front panel I/Q channels. When the probe
has EEPROM identification, the data is unique to that specific probe. When the probe does not have
EEPROM identification, the data will be used for all probes of the same type. The data is also unique to the
channel, so calibration data for the I channel will not be used for the Q channel and vice versa.

CAL:IQ:FLAT:QBAR
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.
The Q-bar port must be connected to the Cal Out port before issuing the SCPI command.

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

This returns 6 integer values: year, month, day, hour, minute, second. When no calibration has been
performed, all values will be 0.
