WIRED RECEIVER

Fig.42
In Fig.42:
1 - WR is on
2 - power mains test indicator
3 - the connected pair of wires (when testing the power mains: "1-2")
4 - the signal level on a marker frequency
5 - "hot buttons"
6 - frequency value on a marker position
7 - marker
8 - spectrum obtained during the last measurement cycle (green color)
9 - maximum signal level at this frequency for all cycles (claret color)
10 - indicator showing the position of the set viewing band relative to the maximum possible
11 - initial and final frequency value of the set viewing band
12 - gain value (in times)
Available actions:
signal analysis at a fixed frequency;
obtaining a difference spectrogram in the DIFFERENTIAL mode;
search of signals in the AUTOMATED mode;
gain setting (x1, x2, x4);
possibility of using an attenuator (20 dB).
Periodically updated graphical information displays the received signals in a given viewing
range. Signals received in the last cycle are marked in green color.
The maximum signal levels (received
during
the range viewing session) are marked in claret
color. The viewing range is display in digital form (Fig.42, item 11) and in graphical form (Fig.42,
item 10).
Horizontal scaling is possible. This enables a detailed view of the part of the range of interest.
To do this, use the or buttons to set the marker on the signal and use the
button to
change the viewing band.
