Data Format Description Of Ota Waveform File - PeakTech 1206 User Manual

8.2.7 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.
