ports. This is the first step in both the I/Q Cable Calibration and the I/Q Probe Calibration.
Next
Perform the I/Q Isolation calibration.
Key Path
Input/Output, I/Q, I/Q Cable Calibration
Remote Command
:CALibration:IQ:ISOLation
Example CAL:IQ:ISOL
Notes All front panel I/Q ports must not be connected to anything.
Notes All cables and probes should be disconnected from the I/Q ports before issuing the SCPI command.
State Saved No.
Initial S/W Revision Prior to A.02.00
Exit
Exits the calibration procedure. All ports calibrated before pressing Exit will use the newly acquired
calibration data.
Key Path
Input/Output, I/Q, I/Q Cable Calibration
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
I/Q Isolation Calibration Time (Remote Command Only)
Returns the last date and time that the I/Q Isolation Calibration was performed. This is a remote query
command only.
Remote Command
:CALibration:IQ:ISOLation:TIME?
Example :CAL:IQ:ISOL:TIME?
Notes This returns 6 integer values: year, month, day, hour, minute, second. When no calibration has been
performed, all values will be 0.
Initial S/W Revision A.02.00
I/Q Cable Calibrate…
The I/Q cable calibration creates correction data for each of the front panel I/Q ports. This calibration data
is used whenever no probe specific calibration data is available. It is important that all ports are calibrated
using the same short BNC cable so that the data is comparable from port to port.
