Setting Number of Channels

Features

  • 32 Channels --> 100000 Hz MaxRate
  • 16 Channels --> 200000 Hz MaxRate
  • 8 Channels --> 200000 Hz MaxRate
where 'Hz' means samples per second

If the selected ChannelCount can not support your current SampleRate, then your SampleRate will be automatically adjusted to the max setting allowed for the selected ChannelCount:

Assume the following setup:
SampleRate = 200000 Hz
ChannelCount = 16 Channels

Now you click the '32 Channels' ChannelCount radio-button.
The SampleRate will automatically change to 100000 Hz.


To set the number of channels on the DAQ832, find the ChannelCount section (circled above in red). Simply Click one of the ChannelCount radio-buttons to select the number of channels. 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).
