Lambda Scan Applications

The Equally Spaced Datapoints Function

The Equally Spaced Datapoints (hp816x_returnEquidistantData) function allows you to select whether you the results will be equally spaced by performing a linear interpolation on the wavelength point and power measurement data, see“Equally Spaced Datapoints” on page 236 for more details.

This function is used because Lambda Scan functions make use of Lambda Logging to log the exact wavelength that measurements were triggered at. This results in Lambda Array wavelength points that are not equally spaced.

Lambda Logging is not available if your Tunable Laser module firmware

N O T E

revision is lower than 2.0.

 

 

 

 

Equally Spaced Datapoints is enabled as a default.

 

The Register Mainframe Function

 

Use the Register Mainframe (hp816x_registerMainframe) function to

 

register your mainframe as a participant in a Multi Frame Lambda Scan

 

operation. The mainframe must be connected to the GPIB bus and have

 

their Input Trigger Connector connected to the Output Trigger Connector

 

of the Agilent 8164A/B Lightwave Measurement System mainframe that

 

the Tunable Laser module is installed in.

 

The Unregister Mainframe Function

 

Use the Unregister Mainframe function (hp816x_unregisterMainframe) to

 

remove a mainframe from a Multi Frame Lambda Scan operation and clear

 

the driver's internal data structures.

 

If you use LabView 5.0 the following items should be noted:

 

• All multi frame functions are not re-entrant, if the driver is running and

 

initialized more than once, results may be unpredictable.

 

• To avoid wrong results, call the Unregister Mainframe function prior to

 

the Initialize function (hp816x_init). This is especially necessary during

 

program debugging, if the Close function (hp816x_close) is not called.
