Setting Up the System

Selecting the Wavelength Calibration and Its Function

 

Selecting the Wavelength Calibration Data

 

You enter the user wavelength calibration data over the GPIB (see

 

“User Calibration Commands” on page 123).

 

Using your own wavelength calibration data, you can use the

 

attenuator to compensate for the total wavelength dependence of

 

your hardware configuration.

 

 

NO T E

If you are using the instrument in an environment where the

 

temperature changes, you should not use the user wavelength

 

calibration data, as it lacks correction for temperature changes.

 

 

To select the wavelength calibration data to use

1.Press SYST repeatedly until USERCAL is shown at the bottom of the display.

2.Select the wavelength calibration data using the Modify keys.

OFF means that the instrument uses the factory-made wavelength calibration data

ON means that the user wavelength calibration data is used.

While it is ON, USERCAL is shown at the bottom left of the display (U/L-CALis shown if the LAMBDCAL is also on).

Resetting the Wavelength Calibration Data Set

To reset USERCAL, press and hold SYST until the value resets (this takes approximately two seconds).

USERCAL resets to OFF.
