Description

lTimestamp

int64

The timestamp is stored as a 64 bit signed number, representative of the time of capture of the first sample in the chunk block, in microsecond resolution. It is stored as the number of microseconds since beginning of the epoch (i.e., 1st January 1970 midnight).

awIQData

int16 [length of IQ data array]

IQ pairs of signed int16 short numbers. Note that regardless of the number of valid bits, the most significant bits in each short should be used. This allows us to specify the full-scale level without needing to specify the number of bits.
