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.
