The time duration between two adjacent sampling points: Indicates the
corresponding time interval between two adjacent sampling points of received
waveform data (4 bytes). The time interval is indicated by floating point format
which compatible with IEEE 754 standards.
Note: This block uses little-endian byte ordering. See the demo code of
Appendix A for more conversion information
Channel indicator: Show the channel which sent the waveform data (1 byte).
1→Channel one 2→Channel two
3→Channel three 4→Channel four
Reserved Data: Not used (3 bytes).
Waveform data: Depends on the specify record length, the effective waveform data
which covers 500 points (1000 bytes), 5000 points (10000 bytes), 12500 points
(25000 bytes), or 25000 points (50000 bytes).
Each point is composed by two bytes (the integer value of 16 bits). The high byte
(MSD) will be prior transferred.
