INPut Commands

Description This command sets the calibration factor for the instrument from the current attenuation factor. The filter attenuation is not affected. The offset is set so that the attenuation factor becomes zero.

CalNEW(dB) = -Attfilter(dB) = CalOLD(dB) - AttOLD(dB)

<value>[DB]MINDEFMAX

Description

This command sets the wavelength for the

 

instrument. The value is used to make the

 

compensation for the wavelength dependence

 

of the filter, using the wavelength calibration

 

data.

NO T E

There are two sets of wavelength calibration data, one is made in the

 

factory, individually, for your instrument. The other is left for the you

 

to define. Using your own wavelength calibration data, you can use the

 

attenuator to compensate for the total wavelength dependence of your

 

hardware configuration.

 

For more details on this topic, see “Selecting the Wavelength

 

Calibration and Its Function” on page 67.

 

You set the wavelength by sending a value

 

 

(default units are meters), or by sending MIN,

 

DEF or MAX, which specify the minimum,

 

default and maximum values for the

 

wavelength.
