ST300 SPIDER
32
In the automatic mode table, only distances to anomalies with the strongest reflection are shown. This
is sufficient for a preliminary assessment as to whether there are any crude connections to the cable, and
for identifying the suspect pair of wires.
For more detailed information on all the responses registered during the testing of the pair in question,
select the corresponding line in the table, wait for the measuring process to start (running dots will
appear) and press “MODE” or “ESC”.
The main screen of the “REFLECTОMETER” mode (Fig.37) will appear, and measuring will start
immediately in the active table. The numbers of wires (2, Fig.37) will correspond to those previously set
in the automatic mode table. To return to automatic measurements, press “MODE”. The obtained results
will remain in the table, and the table cursor will be set at the pair of wires that has been tested from
the main screen.
3. BASIC SEARCH ROUTINES WITH ST300
A basic search routine is a set of actions aimed at finding eavesdropping devices of a certain
type. One basic search routine may utilize one or more operation modes of ST300, as well as
its accessories, and other detection equipment. Basic search routines form the basis for more
complex procedures of testing different cable lines.
Basic search routines with ST300:
– detection of low-frequency signals in low-current lines;
– detection of high-frequency signals in power mains and low-current lines;
– nonlinearity detection in lines;
– anomaly detection in lines;
– cable tracing;
– locating a detected wire-connected eavesdropping device.
As cable lines are the subject of analysis with ST300, before describing basic search routines
with the device, let us take a look at typical ways of connecting it to various cables.
3.1 PHYSICAL CONNECTION TO THE TESTED LINE
Recommended ways of connecting the device to the tested lines are described below,
depending on the object of analysis and the specifics of the cable line.
Fig.42
Fig.42 shows a
1А
type connection of the
device to power mains equipped with a standard
socket.
The connection is made with:
– Mains Adaptor (13, Fig.1)
– Cable with electric plug (6, Fig.1).
Operation mode used:
“WIRED RECEIVER”.
Targeted Threats:
active hard-wired high-
frequency transmitters (transmitting within the
operational frequency band of ST300’s receiver).
