User Calibration Commands

This is done with the :UCALibration:STARt command

10.λ =λ Start

11.Repeat the following steps until λ >λ Stop.

a.Set λ on the tunable laser source, the attenuator and the power meter.

b.Read the power (Power).

c.Power = -Power.

d.Set the user calibration value to Power.

This is done with the :UCALibration:VALue command

e. λ = λ + λ Stepsize

12.Stop the user calibration.

This is done with the :UCALibration:STOP command

:UCALibration:STARt

Syntax

:UCALibration:STARt <wsp>

 

<start_value> , <step_value>

Description

This command starts the entering of the user

 

calibration data.

 

You must send two values with this command,

 

the wavelength of the first calibration point,

 

and the spacing between the calibration points.

 

The default units for both values are meters.

The minimum value for the start wavelength is 1200nm, and the minimum value for the step size is 0.1nm, the maximum value for the step size is 10nm. Other than this, the start and step values must satisfy the formula

start value + ((number of step - 1) × step value} ≤ 1650nm

where the number of steps must be in the range 10 to 401.
