Spectrum Analyser Operating Mode; Spectrum Operating Mode - Promax 8 plus Manual Del Usuario Y Operador

The
CTB
parameter allows to define the method
of measurement for the CTB. IN CH
(within the channel) is the suitable
method whenever the carrier of the channel in study
can be turned off. If it is not possible, as approach,
any other channel (free) can be defined for the
measurement of the CTB.
Parameters
frequencies where the CSO is measured (the PROMAX-8+ admits values from -0.5 to
-2.50 and from 0.5 to 2.5 MHz). These parameters are modified digit to digit, beginning
by the one of smaller weight.
To leave the configuration menu of the CHANNEL-FREQUENCY mode, just press
the key of the operating mode you wish to access.

4.2.4 SPECTRUM ANALYSER operating mode.

Pressing the
mode. This function has 4 different operating modes (SPECT, MAX, MIN and TRANS),
which are selectable through the spectrum mode configuration menu (see section
4.2.4.5).
4.2.4.1

SPECTRUM operating mode.

In the SPECTRUM mode, the PROMAX-8+ provides a spectral analysis of the
band; the span and the reference level are variable. The spectral analysis can be done
in the forward band or in the reverse band as it is selected in the spectrum
configuration menu (section 4.2.4.5); this menu also allows to select the detector used
for the representation of the spectrum between peak and average.
The marker frequency is displayed in the
higher left hand corner of the screen (650.00 MHz)
and, to its right, the frequency signal level (34 dBµV).
To alter the marker frequency turn the rotary selector
[9].
