Command 107 Oversampling Burst
New in firmware version 6.06227, t his command controls the oversampling of data for slower rates of data
collection. Currently it works with all available analog channels and will not work if a sonic channel is
enabled. For best results, the minimum allowed sample interval sent in Command 3 is 0.2 seconds per
sample. Also, the duration of an oversampling burst should not exceed ½ of the sample interval sent in
Command 3.
Syntax: {107,rate,samples}
Parameter List:
rate
– sample interval for oversampling bursts
rate value Description
0.0001 – 16,000 Interval between samples in each burst.
samples – number of samples to take at high rate. These samples are averaged to produce a valid data
point
Samples value
Description
0 Turn off the oversampling burst. Oversampling burst is also
turned off if a Command 0 (Reset) is sent.
1 – 12,000 Number of samples to be taken in each burst.
Return values: No information is returned. Data is retrieved as normal after data collection is
completed.
Example 1: Collect data twice a second for one minute, where each recorded sample is the average of an
oversampling burst consisting of 100 samples at 1000 sample/second (0.001 seconds/sample).
