Parameter Summary
Parameter Type Description
nscan DWORD Number of readings in a single scan
zeroPos DWORD Position of the zero reading within the scan
readingsPos DWORD Position of the readings to be zeroed within the scan
nReadings DWORD Number of readings immediately following the zero
reading that are sampled at the same gain as the zero
reading
counts DWORD Raw data from one or more scans
scans DWORD Number of scans of raw data in the counts array
Parameter Values
nscan: valid values range from 1 to 272
zeroPos: valid values range from 1 to 272
readingsPos: valid values range from 1 to 272
nReadings: valid values range from 1 to 270
counts: a pointer to an array ranging from 0 to 65,535
