Gettraces; Gettracepolarization - JDS Uniphase SWS15100 User Manual

Function Description
C prototype int isTraceDone( );
VB prototype Declare Function isTraceDone Lib "SWS15100" () As Long
Input None
Output None
Return Value When the trace is done, the function returns 1.
When the trace is not done, the function returns 0.
When there is an error, the return value contains the error number (< 0).

getTraces

Function Description
Purpose The getTraces function stores the raw data, to cache, acquired through a call
to the triggerTrace function.
C prototype int getTraces( unsigned short *channelList, unsigned short numChannels);
VB prototype Declare Function getTraces Lib "SWS15100"
(ByRef channelList%, ByVal numChannels%) As Long
Input *channelList is a pointer to the channel list; numChannels is the number of
channels from which data is to be collected.
Output None
Return Value When there is no error, the function returns the number of bytes written to
cache.
When there is an error, the return value contains the error number.

Function Description
Purpose The getTracePolarization function retrieves the polarization of the acquired
trace collected with the getTraces function.
C prototype int getTracePolarization( short *polar );
VB prototype Declare Function getTracePolarization Lib "SWS15100" ( ByRef polar% ) As
Long
Input None
Output short *polar:
This is a set of integers defined as: { S0 = 0, S1 = 1, S2 = 2, S3 = 3, S4 = 4,
POLARIZATION_END_MARKER = 5 }.
