SPECTRUM ANALYSER mode configuration

Pressing the CONFIG key [14] will
access the parameter configuration menu
for the SPECTRUM function.
To change the value assigned to one
parameter, turn the rotary selector [9] until its field is
activated (this will appear shadowed) and then
press. The value of the parameter will be
activated and may be changed by turning the
rotary selector. When the value you want appears, press the rotary selector [9] to
validate it.
The parameters that can be modified through this menu are:
a) BAND
It selects the analyzed band between:
RETURN PATH Sub-band spectrum (5 to 100 MHz).
FORWARD
b) MODE
It selects the representation mode:
SPECT
MIN
MAX
TRANS
c) DETECTOR (Only for the SPECT, MAX and MIN modes)
It selects the used detector between:
PEAK
AVERAGE
In the TRANS mode the detector used is always PEAK.
d) REF. LINE
It permits to activate / deactivate and to define the reference line level in 1 dB
steps from 20 to 120 dBµV (dBµV units). 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 60 dBµV).
e) 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.
