Figure 27.- CH-FR configuration 2/2.
Figure 28.- SPECT mode.
The parameters AUDIO FREQ., CHANNEL BW and NOISE FREQ. are
changed digit by digit, starting at the lowest weight.
To accede to the second page of the configuration menu, press CONFIG [14]
key again.
The CTB SHOWED 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
∆
FCS01,
∆
FCS02,
∆
FCS03
and
∆
FCS04 allow to modify the frequencies where the CSO is measured (the
PROMAX-10
Premium
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.
Finally,
∆
FCH parameter allows to set the frequency offset for the channel
tuning (PROMAX-10
Premium
admits values from –2.00 to 2.00 MHz).
IMPORTANT
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
key the unit switches to the SPECTRUM ANALYSER
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-10
Premium
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 return path 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].
