11 Using the Wavelength

Calibration Software

The Wavelength Calibration software uses a Hydrogen Cyanide (H

13

C

14

N)

absorption cell with 100 torr of pressure. Considered as a calibration
reference, it covers the region from 1530 nm to 1560 nm and uses 16 very
precise lines to perform the calibration.

This software performs scans using the H

13

C

14

N cell as a DUT and

compares the measured spectral values with the certified spectral values.
The software then analyses the average deviation and calculates a
correction factor to be applied to the calibration of the IQS-9401
Wavelength Reference Module (WRM).

Overview of the Application

The application's interface is divided into several steps; each step must be
performed correctly before gaining access to the next step. Because the
application is based on a Wizard (i.e. Next and Back buttons are used to
move from window to window), the Next button is not available until the
step has been completed.

Simply follow the Wizard to determine which step to perform: the step to
perform and that is in progress will be displayed in bold; and a green
checkpoint will appear to the left of the steps already completed.

The Stop button is available only during certain steps, which are
Wavelength Response, Reference and Acquisition. A progress bar as well
a message will always be present above this control indicating the
operation presently in progress.

If necessary, online help is available by clicking Help, then Online Manual.
In addition, the Quit button is accessible at all times.

To start the application:
from the Start menu, select Programs >EXFO >IQS-12004B >Tools >
IQS-12004B Wavelength Calibration.
