The Agilent 816x VXIplug&play Instrument Driver Lambda Scan Applications
242 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
2If the Step Size is too small and results in a trig ger frequency that is to
high for the installed Power Meters, the error "cou ld not calculate a
sweep speed!" will be returned. Increase the Step Size.
3If the chosen wavelength range is too large and Step Si ze is too small,
the error "too many datapoints to log!" wil l be returned. In this case,
reduce the wavelength range and/or increas e the Step Size.
The Get MF Lambda Scan Parameter s Function
The Get MF Lambda S can Parameters
(hp816x_getMFLambdaScanParameters_Q) function returns all
parameters that th e 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_e xecuteMfLambdaScan)
function runs a Lambda Scan operation and returns an array that contains
the wavelength values at which po wer measurements are made.
That is, it executes an operation whe re a Agilent 8164A /B Lightwave
Measurement System with a back-loadable Tunable Laser modul e and up
to 100 Power Sensors installed, performs a wavele ngth sweep where the
Tunable Laser module and Power Sensors are coordinate d with each
other.
Use the values returned from the Prepare Multi Fram e 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 Mul ti Frame Lambda Scan
operation.
