Q-Bar Port - Keysight x-series User Reference Manual

Initial S/W Revision

Q-bar Port

The Q-bar port calibration is performed with the probe body attached to the front panel's Q-bar port and
the probe tip connected via an adapter to the Cal Out port. The Q-bar probe calibration is only available for
passive probes with Differential On. The guided calibration will show a diagram of the required
connections.

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.

The Q-bar port must be connected to the Cal Out port before issuing the SCPI command.
The calibration data is saved as soon as the port is calibrated and will survive power cycles. It is not
