CALibration Subsystem

Function

Queries the calibration of the IQ modulator for RF generator 1. It takes some time to complete calibration and can't be aborted except by cycling the power switch.

• Calibrates the IQ modulator for RF generator 1.

• Returns a value indicating success or failure of calibration.

Query

Range:

• 0 = Pass

• -340 = Fail

Requirements

Test Application Revision: A.01.00 and above

Programming Example

"CALibration:IQ1?"

Function

Queries the calibration of the IQ modulator for RF generator 2. It takes some time to complete calibration and can't be aborted except by cycling the power switch.

• Calibrates the IQ modulator for RF generator 2.

• Returns a value indicating success or failure of calibration.

Query

Range:

• 0 = Pass

• -340 = Fail

Requirements

Test Application Revision: A.01.00 and above

Programming Example

"CALibration:IQ2?"

Function

Starts the Calibrate Measurements routine. When this calibration has completed, a value is returned to indicate the success or failure of the calibration. Zero indicates the calibration completed successfully.

Ensure that your test set has warmed up at least 30 minutes and that no power is present at the front panel RF connectors before performing any calibrations.

Query

Range:

• 0: Measurement calibration completed successfully.

• 1: Measurement calibration failed due to temperature drift. Wait for temperature to stabilize.

• 2: Measurement calibration failed due to oven out of range.

• 3: Measurement calibration failed due to loopback switch problem.

• 4: Measurement calibration failed due to under range condition.

• 5: Measurement calibration failed due to over range condition.

• 6: Measurement calibration failed due to correlation problem.

• -340: Measurement calibration failed. This is a SCPI defined value indicating an unexpected case.
