Setting Global Sample Rate

Features

  • 6250 Hz -> 32 Channels Max
  • 12500 Hz -> 32 Channels Max
  • 25000 Hz -> 32 Channels Max
  • 50000 Hz -> 32 Channels Max
  • 100000 Hz -> 32 Channels Max
  • 200000 Hz -> 16 Channels Max
where 'Hz' means samples per second

If you try to select a SampleRate which is too high for the number of channels, your SampleRate will be automatically adjusted to the max setting allowed for the current ChannelCount.

Assume the following setup:
SampleRate = 50000 Hz
ChannelCount = 32 Channels

Now you click the '200000 Hz' SampleRate radio-button.
The SampleRate will automatically change to 100000 Hz.

To set the sample rate for all channels on the DAQ832, find the SampleRate section (circled above in red). Simply Click one of the SampleRate radio-buttons to select the sample rate. Note: The max number of samples per second is 3.2 Million (6.4MB/s), therefore the more channels you have, the lower the rate has to be (as shown in the above Features).

Regular Mode

When DynaDAQ runs at 3.2MB/s or less, DynaDAQ is in RegularMode. In this mode, DynaDAQ performs optimizations on the realtime data while recording. These optimizations allow the DynaDAQ Viewer to graph the data file very quickly. For example, if data was recorded for 30 minutes at 3.2MB/s, then the data file size would be 5.76GB. With optimizations the file would be loaded in about 13 seconds.

NOTE: If DynaDAQ is currently in EnhancedMode (6.4MB/s) and you change to RegularMode (3.2MB/s or less), the following message box will appear:

Enhanced Mode

Enhanced mode is a feature in which DynaDAQ runs at 6.4MB/s. In this mode, DynaDAQ does not perform optimizations. Without optimizations, the same 5.76GB data file would load in about 10 minutes. With the Enhanced mode, you gain realtime speed at the expense of post processing time.

NOTE: If DynaDAQ is currently in RegularMode (3.2MB/s or less) and you change to EnhancedMode (6.4MB/s), the following message box will appear:

While in EnhancedMode, the Enhanced checkbox will appear (as shown below in red).
