Example 1
You are scanning at 1000 samples/second and have 2 channels in Channel Group A recorded at 1000
samples/second. The first recorded scan is always recorded with absolute data, to be an initial point of
reference. Notice that the Scan ID and channel data are in little-endian format.

Example 2
You are scanning at 1000 samples/second and have 2 channels in Channel Group A and 1 channel in
Group B. Group A is recording at 500 samples/second and Group B is recording at 200 samples/second.
The first recorded scan is always recorded with absolute data, to be an initial point of reference. Notice
that the Scan ID and channel data are in little-endian format.
