Lambda Scan Applications

2If 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.

3If 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 Lambda Scan Parameters Function

The Get Lambda Scan Parameters

(hp816x_getLambdaScanParameters_Q) function returns all parameters that the Prepare Lambda Scan (hp816x_prepareLambdaScan) function adjusts or automatically calculates.

The Execute Lambda Scan Function

The Execute Lambda Scan (hp816x_executeLambdaScan) function runs and returns the results of a Lambda Scan operation.

That is, it executes an operation where a Agilent 8164A/B Lightwave Measurement System with a back-loadable Tunable Laser module and up to four Power Sensors installed, performs a wavelength sweep where the Tunable Laser module and Power Sensors are coordinated with each other.

The Prepare Lambda Scan (hp816x_prepareLambdaScan) function must be called before a Lambda Scan operation is executed. Use the return values of this function (Number of Datapoints and Number of Power Arrays) to allocate arrays for the Execute Lambda Scan (hp816x_executeLambdaScan) function.

Equally Spaced Datapoints is enabled as part of this function and cannot be disabled. Use Multi Frame Lambda Scan if you need to have inequally spaced datapoints. See“Equally Spaced Datapoints” on page 236 for more details.
