Note:
Offset data factor is a 4 byte floating point number starting at address 0xA0.
Amplitude scale factor data is a 4 byte floating point number starting at address 0x9C.
Waveform descriptor block starts off from “WAVEDESC” in the return data. The size of the
descriptor is 0x16e – 0x15 + 1.
All waveform data are represented in two’s complement binary. It must be converted to
decimal and apply to the linear equation formula y = mx + b, where x is the data in decimal
value, m is the amplitude scale factor, and b is the offset data factor.
