The Agilent 816x VXIplug&play Instrument Driver Lambda Scan Applications
242 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition

If the Step Size is too small and results in a trigger frequency that is to
high for the installed Power Meters, the error "could not calculate a
sweep speed!" will be returned. Increase the Step Size.
3 If the chosen wavelength range is too large and Step Size is too small,
the error "too many datapoints to log!" will be returned. In this case,
reduce the wavelength range and/or increase the Step Size.
The Get MF Lambda Scan Parameters Function
The Get MF Lambda Scan Parameters
(hp816x_getMFLambdaScanParameters_Q) function returns all
parameters that the Prepare Multi Frame Lambda Scan
(hp816x_prepareMfLambdaScan) function adjusts or automatically
calculates.
The Execute Multi Frame Lambda Scan Function
The Execute Multi Frame Lambda Scan (hp816x_executeMfLambdaScan)
function runs a Lambda Scan operation and returns an array that contains
the wavelength values at which power measurements are made.
That is, it executes an operation where a Agilent 8164A/B Lightwave
Measurement System with a back-loadable Tunable Laser module and up
to 100 Power Sensors installed, performs a wavelength sweep where the
Tunable Laser module and Power Sensors are coordinated with each other.
Use the values returned from the Prepare Multi Frame Lambda Scan
(hp816x_prepareMfLambdaScan) function to set the parameters of the
Execute Multi Frame Lambda Scan (hp816x_executeMfLambdaScan)
function.
The Get Lambda Scan Result Function
The Get Lambda Scan Result (hp816x_getLambdaScanResult) function
returns for a given Power Meter channel a power value array and a
wavelength value array.
These arrays contains the results of the last Multi Frame Lambda Scan
operation.
The Get Number of PWM Channels Function
The Get Number of PWM Channels
(hp816x_getNoOfRegPWMChannnels_Q) function returns the number of
Power Meter channels in a test setup.
