To initialise the TIME and COUNTER fields, press the SPECT [13] key.
In the lower part of the screen it appears a bar that shows present level, a
dotted line shows the detection threshold (REF. LINE) whereas the continuous line
indicates the maximum detected level.

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 80 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).
