4.2.4.4
TRANSIENT DETECTOR operating mode
IMPORTANT
The Transient detector mode is only operative in the reverse band.
The TRANSIENT DETECTOR mode allows to count the number of transitory
with a level higher than a certain threshold. The threshold is defined by the user
(between 20 and 60 dBµV) as well as the detection frequency range.
The SCAN field shows the margin of
frequencies on which the detector acts (the
higher frequency can be reduced by means of
the
STOP. FREQ. parameter on the
configuration menu).
The lower line (TIME) shows the time since the
detector is active.
Figure 32.- Transient detector mode.
The COUNTER field shows the number of impulses that have exceeded the
level defined by the REF. LINE parameter in the configuration menu of the SPECT
mode (section 4.2.5.5).
To initialize 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.
