6 RLC Swept SA Measurement Front-Panel & SCPI Reference
Input/Output
The guided calibration (front panel only) will show connection diagrams and guide you through
the isolation calibration and 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 you press
"Exit" to exit the calibration process, the data for the ports 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 I/Q ports. 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 keys 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. You 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.
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:FLAT: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 port will be displayed. Any calibrations that are more
than a day older than the most recent calibration will be displayed with the color amber.
