Isdarkvoltagedone; Getaveragedarkvoltagepower - JDS Uniphase SWS15100 User Manual

Function Description
Return Value When there is no error, the function returns the value of the polarFlag as set by
the function setPolarizationControl ( ).
When there is an error, the return value contains the error number.

isDarkVoltageDone

Function Description
Purpose The isDarkVoltageDone function is used to check if a dark voltage
measurement has been performed for the specified channel.
C prototype int isDarkvolatgeDone( unsigned short chID, char *timeStamp )
VB prototype Declare Function isDarkVoltageDone Lib "SWS15100" (ByVal chID%, ByVal
timeStamp$) As Long
Input unsigned short chID:
This is the channel to be checked.
Output char *timeStamp:
This is the time of the last zero loss reference for the specified polarization. At
least 32 characters must be assigned to this array.
Return Value When a dark voltage measurement has been done for the specified channel,
the return value is 1 (TRUE).
When a dark voltage measurement has been done for the specified channel,
the return value is 0 (FALSE).
When there is an error, the return value contains the error number.

getAverageDarkVoltagePower

Function Description
Purpose The getAverageDarkVoltagePower function is used to get the average power
measured during a dark voltage measurement. This function is called after the
dark voltage measurement for the specified channel has been performed.
C prototype int getAverageDarkVoltagePower( unsigned short chID, double *dAvePower)
VB prototype Declare Function getAverageDarkVoltagePower Lib "SWS15100" (ByVal
chID%, ByRef dAvePower As Double) As Long
Input unsigned short chID:
This is the channel number.
Output double *dAvePower:
This is the average dark voltage power in dBm.
Return Value If there is no error, the return value is 0.
If there is an error, the return value contains the error number.
