RF channel table
In order to obtain a meaningful representation of the spectrum analysis, the
RF chan-
nel table
stored in the VX 52 B / VX 53 B should match your downstream channel
lineup.
The channel table consists of semicolon-separated values in a *.csv file with the fol-
lowing line format:
[frequency];[modulation format]<CR><LF>
[frequency]
RF channel frequency in kHz
PAL: carrier frequency / QAM: center frequency
;
Column separator: “;” [semicolon]
[modulation format]
CW (unmodulated) / PAL / QAM
(necessary for correct sensor calibration)
<CR><LF>
Line break - typically given by the spreadsheet / text editor
example.csv:
311250;PAL
319250;PAL
330000;QAM
338000;QAM
