Keysight x-series User Reference Manual page 215

The guided calibration (front panel only) will show connection diagrams and guide the user through the I/Q
Isolation Calibration and through calibrating each port. The calibration data for each port is stored
separately, so as soon as a port is calibrated that data is saved and will be used. If a user presses "Exit" to
exit the calibration process, the data for the port already completed will still be used. It is recommended
that a calibration be completed once started, or if exited, that it be properly done before the next use of the
probe. The "Next" button will perform the calibration for the current port and then proceed to the next step
in the calibration procedure. The "Back" button will return to the prior port in the procedure. Both softkeys
and dialog buttons are supplied for ease of use. The dialog buttons are for mouse use and the softkeys for
front panel use.
The calibration can also be done via SCPI, but no connection diagrams will be shown. The user will have to
make the correct connections before issuing each port calibration command. Again, it is recommended that
all ports be calibrated at the same time.
For Active probes or when Differential is Off, only the main port is calibrated, otherwise both the main and
complementary ports are calibrated.
The instrument state remains as it was prior to entering the calibration procedure except while a port is
actually being calibrated. Once a port is calibrated it returns to the prior state. A port calibration is in
process only from the time the "Next" button is pressed until the next screen is shown. For SCPI, this
corresponds to the time from issuing the CAL:IQ:PROB:I|IB|Q|QB command until the operation is complete.
For example, if the prior instrument state is Cal Out = Off, Input = I+jQ, and Differential = Off, then up until
the time the "Next" button is pressed the I Input and Q Input LEDs are on and the Cal Out, I-bar Input and
Q-bar Input LEDs are off. Once the "Next" button is pressed for the I port calibration, only the Cal Out and I
Input LEDs will be on and the others will be off. When the screen progresses to the next step ("Next" button
again enabled), the prior state is restored and only the I Input and Q Input LEDs are on (Cal Out is off again).
The last calibration date and time for each relevant port will be displayed. For passive probes with
Differential On, any calibration that is more than a day older than the most recent calibration will be
displayed with the color amber.
I Port
The I port calibration is performed with the probe body attached to the front panel's I port and the probe tip
connected via an adapter to the Cal Out port. The guided calibration will show a diagram of the required
connections.
