Appendix G: Frequency Presets File
Default frequency presets can be modified by the user by supplying a special text file stored on
the analyzer’s disk. The file name must be “presets.txt” and the format for each band entry in the
file is as follows:
legend, start_freq, stop_freq, def_mul_freq, def_mul_span, marker1_freq, marker2_freq
Where:
o legend: string to be displayed in the preset menu (max length: 20)
o start_freq: start frequency, specified in MHz
o stop_freq: stop frequency, specified in MHz
o def_mul_freq: default multiplier for setting the frequency
o def_mul_span: default multiplier for setting the span
o marker1_freq: default marker 1 frequency, specified in MHz
o marker2_freq: default marker 2 frequency, specified in MHz
