The frequency attribute specifies the sampling frequency (in hertz) at which a dataStream captures and records data.
Name | Type | Description |
---|---|---|
integer | integer | A positive integer specifying the frequency in hz. |
Although there is no theoretical limit to high the frequency can be set, there may be practical limits to how fast Inquisit can capture and record data on a given device. The default is 60 hz.
The following dataStream captures mouse coordinates at a frequency of 75 hz.
<dataStream mousetracking>
/ columns = (date, time, subject, dataStream.mousetracking.elapsedTime, trialcode, stimulusItem, stimulusItem, mouse.x, mouse.y)
/ frequency = 75
</dataStream>
