DESCRIPTION PARAMETER VALUES
Power measurement in digital
channel
DETECTOR AVERAGE
: Power measurement
in digital channel by integrating
method.
PEAK
: Power measurement
maximum in digital channel.
(
only when tuning by frequency
)
Frequency mode
MODE FREQ.
LEV
: Level measurement.
DIG
: Power integration.
The parameters
CHANNEL BW
and
NOISE FREQ.
are changed digit by digit,
starting at the lowest weight.
Finally,
∆
FCH
parameter allows to set the frequency offset for the channel tuning
(
PROPOWER-5
admits values from 2.00 to —2.00 to MHz), i.e. the displacement of the
channel tuning frequency for those channels that present a central frequency displaced
respect to the one of the corresponding standard system.
Also this parameter (
∆
FCH
) can be edit in the channel configuration by means of
CONFIG CH-FR
option.
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
PROPOWER-5
provides a spectral analysis of the
band; the span and the reference level are variable. The spectral analysis can be done
in the band from 1 MHz to 50 MHz. 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 (25.00 MHz) and, to its
right, the frequency signal level (-6 dBm). To alter the
marker frequency turn the rotary selector [9].
