The total sample throughput rate is the rate that your instrument acquires samples for all channels combined. For example, to acquire two channels of data at 100Hz each would require a sample throughput rate (total scanning rate) of 200Hz (2 channels × 100Hz = 200Hz). The Sample Rate must be specified before recording; default varies.
Specify a throughput sample rate:
WinDaq Acquisition automatically allocates the correct amount of buffer space when you input a sample rate. The Input Buffer Size and Disk Buffer Size values are displayed for informational purposes only.
Keep in mind that the sample rate is actually a throughput rate. The sample rate per channel (obtained by dividing the selected sample throughput rate by the number of channels enabled) is displayed in the lower left corner of the window as S/s/CHAN: (samples per second per channel).
Although thousands of different sample rates may be configured, some discrete rates are not attainable. This limitation is due to the inability to divide the master clock in a manner that results in an even-numbered quotient.

DI-149 products require you to enter a per channel sample rate when setting the sample rate.
DI-2108 products require you to enter a per channel sample rate when setting the sample rate. The DI-2108 also provide the ability to set a sample interval instead.
Please Note: WinDaq/Lite will display a total sample throughput rate of 10,000 Hz (or 1250 Hz per channel) but will not record at rates over 240 Hz throughput (30 Hz per channel). You must purchase WinDaq/HS to record at rates over 240 Hz throughput.
