reference wavelength.
unsigned short uhListSize :
This specifies the size of the array containing the out-of-band wavelengths.
double *pdLamOutWaveList :
This is the array of out-of-band wavelengths for which crosstalk is calculated.
double dBandWidth :
This specifies the bandwidth within which to compute peak powers around
each out-of-band wavelength.
Output double *pdInPowPeak:
This is the peak power in the in-band channel. The peak is found around the
reference wavelength, going a half-bandwidth on either side.
double *pdLeftOutPower:
This is the power in the out-of-band channel to the left of the reference
wavelength.
double *pdRightOutPower:
This is the power in the out-of-band channel to the right of the reference
wavelength.
double *pdTotalOutPower:
This is the total power in the out-of-band channels.
Return Value When there is no error, the function returns zero.
When there is an error, the return value contains the error number.
getChannelList
Function Description
Purpose The getChannelList function retrieves all the channels present on the SWS
system. Values are returned in an array list. The size of the array must be 128.
The active channels are filled from the beginning of the array. The rest of the
array, up to 128, is filled with 0.
To work properly, this function must have an array of 128 unsigned short
elements allocated for the active channel list.
C prototype unsigned short getChannelList( unsigned short *channelList );
VB prototype Declare Function getChannelList Lib "SWS15100"
(ByRef channelList%) As Long
Input Unsigned short *channelList :
The channelList array contains all the channels that are present on the SWS
system.
