SECTION 6: CONDUCTING A SWEEP
93 REI OSC-5000E
BASIC PROCEDURE FOR A SWEEP
This section provides a general recommended procedure for conducting a sweep. These
procedures are general in nature and do provide detailed OSCOR procedures. Detailed
OSCOR procedures are previously provided in this manual and only referenced in this
section. It should also be understood that there are many factors that may affect how a
sweep is performed. Sweep procedures will need to be modified to accommodate these
factors. It is the responsibility of the trained professional to adapt the procedures as
needed. Factors affecting sweep procedures include:
• Reason for conducting the sweep
• Perceived threat level sophistication
• Ambient RF environment
o Internal Wireless systems (WAN, security radios, etc.)
o Location of local antennas (Cell, TV, Radio, Satellite, etc…)
• Size and number of rooms in the target environment (offices, conference rooms,
cubicles, board rooms, presentation rooms, laboratories, engineering offices,
etc…)
• Other security procedures related to the target environment
o Access Control
o Information Security procedures
o Personnel security procedures and background checks
• Contents of the target environment (furniture, computer equipment, electronic
equipment, etc.)
Basic suggested procedure for a dedicated sweep:
1. At least ½ mile (.8 km) from the target building, run the OSCOR in a Load
Friendly mode. Ensure that the memory has been erased for all signal database
data as well as trace data (see page 80 Step 3 Load Friendly Database).
NOTE: If you have generated and stored friendly signals using the OPC Interface
software, simply download the stored information from your PC instead of
Loading Friendly signals from the OSCOR.
2. Before entering the target room, manually check the most common video
frequencies (900-930 MHz, 2.4GHz, 5.7GHz).
3. Activate a known sound source (see page 95 Activating a Known Sound Source).
4. Enter the target room, turn on the OSCOR in the manual mode and clear the
peak trace data. In Whip Hi Sweep Display (this is the default) turn on the Peak
display minus the Friendly display. This will automatically display any obvious
differences in the current environment spectrum compared to the Friendly
spectrum.
5. Differences in these displays should be quickly checked manually for potential
threats. This step will detect most threats very rapidly.
