The frequency attribute specifies the sampling frequency (in hertz) at which a datastream captures and records data.
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>
