Frequency Shift-Keying Source File Specifications

The frequency shift-keying file is used to describe time relations of frequency hopping between frequency 0 and frequency 1. It corresponds with applications in the communication industry where data can be stored in binary or hexadecimal values.

A frequency shift-keying file must start with a character identifier for data parsing. The identifier for binary values is 'binary' and 'hexadecimal' for hexadecimal values. After the identifier, the file can contain an unlimited amount of header information. A carriage return (non-printable character \r\n) marks the start of the data. After the carriage return, the data must follow a continuous stream without any delimiters. The end of data is defined as the first character not valid for specified identifier; a non-printable delimiter or the end of a file.
