Transient Detector Operating Mode; Spectrum Analyser Mode Configuration - Promax PROPOWER - 5 Manual De Instrucciones

Figure 24.- MIN mode. First scan.
Previous figures show an example of this measurement over a digital PLC
channel. Left figure corresponds to the first sweep. After several sweeps (right figure)
an interference is seen at the centre of the channel, which previously remain masked by
the noisy nature of the signal.

4.2.4.4 TRANSIENT DETECTOR operating mode

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 -80 and -40 dBm) 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.
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 4.2.4.5).
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.

4.2.4.5 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.
