Does the DVS capture card have an averaging function?
Our averaging of the signals acquired by the DVS system can effectively improve the signal-to-noise ratio of the signals, thus making it easier to extract the characteristic information of vibration.
The DVS-ETH-100-2 Data Acquisition Card board has a built-in averaging function from the user's point of view.
The acquisition card averages the data obtained from m pulse-triggered samples and compresses the data to one pulse-triggered data.
Where "m" is the number of trigger pulses collected, "n" is the number of points collected per trigger, and the average number of times "m" can be set for the averaged pulse-triggered data for final upload.
Command Format for Enabling Average Function

Definition: the sampling card averages the data collected for each trigger, default value: 0, default off
2、Average number of times（0x0020）
Definition: the average number of times to trigger the acquisition of data, default value: 64, can be set: 8, 16, 32, 64, 128
