Setband; Getpassband - JDS Uniphase SWS15100 User Manual

Output double *pCenLam:
pCenLam stores the center wavelength of the peak.
double *pCenPow:
pCenPow stores the center power of the peak corresponding to the center
wavelength within the specified wavelength.
Return Value When there is no error, the function returns zero.
When there is an error, the return value contains the error number.

setBand

Description The setBand function sets the band for the next trace. The call to this function
switches the dual band selector module to collect data from the appropriate
transmitter.
C prototype Int setBand( unsigned short uhBand);
VB Declare Function setBand Lib "SWS15100"
prototype
(ByVal uhBand%) AS BOOLEAN
Inputs Unsigned short uhBand:
let uhBand = 1 for Band C and 2 for L Band, are valid inputs for the wavelength
band.
Outputs Return value:
When there is no error, the function returns zero.
When there is an error, the function returns an error number.

getPassBand

Description The getPassBand function computes the passband of the largest peak
contained in the pPowData power array. Call the function after obtaining
pPowData array through a call to the getILTrace function. The refpeak
parameter must be specified by the caller.
C prototype
int getPassBand( double *pdLamData, double *pdPowData, unsigned short
dataSize, unsigned short refPeak, unsigned short baseRef, double interLevel,
unsigned short refWave, double *pdPassBand);
VB Declare Function getPassBand Lib "SWS15100" (ByRef pLamData As Double,
prototype ByRef pPowData As Double, ByVal dataSize%, ByVal refPeak%, ByVal
baseRef%, ByVal interLevel as Double, ByVal refWave%, ByRef pdPassBand
As Double) As Long
