Format

daqCalConvert(handle, counts, scans)

Purpose

daqCalConvert performs the calibration of one or more scans according to the previously called

daqCalSetup function.

Parameter Summary

Parameter Type Description

handle DaqHandleT

Handle to the device to be calibrated

counts PWORD

Raw data from one or more scans to be calibrated

scans DWORD

Number of scans of raw data in the

counts array

Parameter Values

handle: obtained from the daqOpen function

counts: a valid pointer to an array of uncalibrated scan data whose size must be at least equal to:

[(scans)* scan size * (the sample size, normally 2 bytes)]

scans: valid values range from 1 to 4,294,967,295; however, memory limitations may apply

Returns

DerrZCInvParam Invalid parameter value

DerrNoError No error

For more details on error messages refer to the Daq Error Table.

Function Usage

The daqCalConvert function will modify the array of data passed to it. The counts parameter specifies a

pointer to an array of the raw A/D counts retrieved during an acquisition. Upon return, the counts array will

hold calibrated data. The scans parameter indicates the number of scans (as defined by the current scan group

configuration) in the acquisition.

This function should be preceded by the daqCalSetup function.

Prototypes
