Measurement Map - SEFRAM 7805B Manuel D'utilisation

4 – MEASUREMENT MAP
With this function you will immediately detect the
problems in multiple frequencies reception.
It is possible to select 12 transponders from the ones you
have stored in a table of parameters
(Refer to « parameters »
First select a histogram by turning the rotary wheel, then press it and finally enter the number of
the setup corresponding to the selected transponder.
The selected transponders are successively measured as for the Level/Power measure.
The frequency, the standard, the band and the polarity corresponding to the selected transponder
can be read at the top of the screen.
5 – SPECTRUM
The graph displayed allows to differentiate easily analog
and digital transponders.
The measure gives the frequency and the level depending
on the position of the cursor. This measure corresponds to
an instantaneous and indicative value. It is not the same as
the one made in the Level/Power measure.
You can change the reference level (vertical scale), the
central frequency (CF) and the span (SP).
The reference level is calculated each time you recall the spectrum screen.
