Easy I/O for DAQ Function ReferenceThis section describes each function in the Easy I/O for DAQ Library. The function descriptions
are arranged alphabetically.
AIAcquireTriggeredWaveforms
short error = AIAcquireTriggeredWaveforms (short device, char channelString[],
long numberOfScans,
double scansPerSecond,
double highLimitVolts,
double lowLimitVolts,
double *actualScanRate,
unsigned short triggerType,
unsigned short edgeSlope,
double triggerLevelV,
char triggerSource[],
long pretriggerScans,
double timeLimitsec,
short fillMode, double waveforms[]);
Purpose
This function performs a timed acquisition of voltage data from the analog channels specified in
the channelString. The acquisition does not start until the trigger conditions are satisfied.
If you have an E Series DAQ device, you can select Equivalent Time Sampling for the Trigger
Type to sample repetitive waveforms at up to 20 MHz. See the help for the Trigger Type
parameter for details.
