getTraceStatus

Function Description
Purpose The getTraceStatus function is used to return the status of the trace.
C prototype int getTraceStatus( );
VB prototype Declare Function getTraceStatus Lib "SWS15100" () As Long
Input None
Output None
Return Value When there is no error, the function returns the status.
The status is bit encoded as follows:
Bit 1(LSB): Card busy = 1, Card Idle=0
Bit 2
Bit 3
Bit 4 to15 : Undefined
When there is an error, the return value contains the negative error number.

getChannelPolarization

Function Description
Purpose The getChannelPolarization function retrieves the polarization of the trace for
the specified channel in cache memory. Note: This function returns the last
polarization for specified channel, the last time any data was collected for the
channel. To find the latest polarization, use getTracePolarization instead.
C prototype int getChannelPolarization( unsigned short chID, short *polar );
VB prototype Declare Function getChannelPolarization Lib "SWS15100" ( ByVal ChID%,
ByRef polar% ) As Long
Input Unsigned short chID:
Channel ID for which polarization is sought.
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 }.
Return Value When there is no error, the function returns zero.
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
