Data format description of OTA waveform file
If the source mode is set to Out1 or Out2, OTA file consists of two parts: the file header
and the channel data. If the source mode is set to Out1&Out2, OTA file consists of three
parts: file header, the first channel data, and the second channel data. The file header
represents the parameter of file data, which is expressed in "parameter name + value".
Each parameter name is a case-sensitive string of 4 bytes. The parameter value is at least
4 bytes.
