Command Syntax

:CALibrate:OPTical:USER:CHANnelN:STARt

Where N identifies a specific channel and must be selected from {1:8}{A|B|C|D}. For example, CHANnel3C.

Description

On N1090A DCA-M extended hardware modules, starts an optical calibration at a user wavelength on the indicated channel. For any other optical module, a user wavelength optical calibration must be performed using the 86100D Legacy user interface.

To specify the wavelength for the calibration, use the :WAVelength sibling command. To specify the optical power used in the calibration, use the :OPOWer sibling command. The wavelength and source power used must be within the ranges listed in the following table.

Optical Calibration Requirements
Module Factory Calibrated Wavelength(s) Allowable Calibration Optical Source Power Level Source Power for Calibration to Meet Specifications
N1090A 850 nm
1310 nm
1550 nm
375 μW to 425 μW
175 μW to 225 μW
175 μW to 225 μW
375 μW to 425 μW
175 μW to 225 μW
175 μW to 225 μW

The minimum power level is recommended to assure specified performance over the instrument's full dynamic range. The calibration accuracy is heavily dependent on the accuracy to which you know the optical source power. For best results measure the optical source power with a high precision optical power meter.

Use the :STATus? sibling query to return details about the current calibration.

Requires FlexDCA revision A.05.00 and above.
