USER'S MANUAL. PROPOWER-5
The parameters that can be modified through this menu are:
a) MODE
It selects the representation mode:
SPECT
MIN
MAX
TRANS
b) DETECTOR
It selects the used detector between:
AVERAGE (Max. SPAN = 30 MHz).
PEAK
c) REF. LINE
It permits to activate / deactivate and to define the reference line level in 1 dB
steps from -80 to -40 dBm. This line appears on the spectrum representation and
also it is the threshold value for the impulses detection in the TRANSIENT mode
(only if its value is under -40 dBm).
d) STOP. FREQ
It defines the maximum frequency for the transient detection.
To leave the configuration menu of the SPECT mode, just press the key of the
operating mode you wish to access.
4.2.5 TILT operating mode.
The TILT operating mode displays on-screen, graphically and numerically, the
difference in level between any four frequencies previously defined as pilots. This
function provides a quantitative measurement about band equalisation.
To access this mode of operation
press the TILT key [12]. The screen will
show a bar-graph of the four pilot channels
and the difference in level (TILT) between the upper
pilot and the lower pilot (- 5 dB in the example). When
the pilots are not present or its level is lower than 20
dBm, the message 'NO PILOTS' will appear. Turning
the rotary selector [9] the reference level may be
modified.
The pilots may be defined in two ways:
a) By frequency
Using the TILT configuration menu. See section 4.2.5.1 Tilt mode configuration.
b) By channel
From the SCAN mode. In order to do this:
07/2006
Instantaneous value.
Minimum values held (MIN INGRESS).
Maximum values held (MAX INGRESS).
Transient detector.
