4.3 USE OF RECEIVER RX5000
4.3.1 Modes
of
operation
for the receiver RX5000
If a TX5000 transmitter is not available, a site can also be probed by means of passive line
location.
The RX5000 receiver is capable of detecting radio signals in the frequency range between
15kHz to 23kHz as well as power signals in the frequency range between 50/60Hz.
The following pictures illustrate how each of the signals couple onto conductors buried in
the ground:
Fig. 10: Use of receiver RX5000
The two options explained above for passive location together with the options of active
location with a transmitter or a probe transmitting a signal with an appropriate frequency
result in the following modes of operation:
Symbol
Mode of operation
RADIO
For locating cables which are carrying VLF reradiated radio signals
POWER GRID
For locating mains power supply cables, through which current with a
grid frequency is flowing
TRANSMITTER
For locating cables or pipes, onto which the signal from an active
transmitter is coupled. The figure indicates the currently selected
frequency which has to correspond to the frequency of the transmitter
