DAT Sample Rate

Controls: DD/Open >> DAT Format >> Sample Rate
Macro: DATrate

Since .DAT-type files don't have a header that Daqarta can use to determine the sample rate that was used to acquire the data, you can use this control to force an arbitrary rate. The default value is 44100 samples per second.

The .DAT Sample Rate setting doesn't affect the appearance of the waveform or its spectrum, but it does affect the X-axis calibration.
