Correction data files must be written in CSV format.
Write a frequency value and a correction value for the frequency with a comma (,) separator. Deal them as a pair, and write pairs for all correction points with comma separators.
Line break characters are recognized as data separators in the same way as commas. Therefore, two formats as shown below are available: writing pairs in a single line, or writing a pair of a frequency value and a correction value in each line.
Write frequencies in Hz, and correction values in dB.
Example of Data Written in Single Line
10E+6,0.04,100E+6,0.06,200E+6,0.07,300E+6,0.06
Example of Data Written in Multiple Lines
10E+6,0.04
100E+6,0.06
200E+6,0.07
300E+6,0.06
There are some restrictions on writing correction data files. They are:
1. The maximum number of data items is 1001. Data after that is ignored when loaded.
2. Lines that start with a pound sign (#) are skipped as comment lines. Data in those lines is not recognized.
3. Data must be written in the order from data for the smallest frequency to data for the largest. If data for a frequency equal to or smaller than the previous one is read, the read operation ends immediately. This does not cause any error, and the correction data immediately before the end of the read operation is reflected.
