SECTION 6: CONDUCTING A SWEEP
REI OSC-5000E 94
6. Set up the OSCOR in the Automatic Mode to search the WhipLo, WhipHi, and
Discone Frequency inputs. Check desired settings and activate Auto Mode. Allow
Automatic mode to run through at least 2 passes for increased reliability.
7. Perform a physical search while the OSCOR runs in Automatic Mode.
8. Review all signals detected in automatic sweep. Designate all known friendly
signals as FRIENDLY. Any unidentifiable signals should be checked for sub-carrier
and video content.
9. Review all Friendly signals for the presence of Snuggle bugs.
10. Manually check infrared input (see page 96, Considerations for Infrared and
Laser Threats).
11. Manually check for signals above 3GHz using the MDC-2100 (if you have this
option).
12. Manually check electrical outlets using power cord (AC VLF) for carrier current
(see page 97 Checking For Carrier Current Threats).
13. In the Sweep mode turn on the Peak display minus the Real-Time display. This will
automatically display any signals that are intermittent in nature. This display
should be examined for both Whip Hi and Discone. For example, if any energy
from a burst or frequency hopper has been encountered sometime during the
previous sweep activities, the evidence will be displayed in the Peak display minus
the Real-time display.
14. Differences in these displays should be quickly checked manually for potential
threats. This step will detect sophisticated threats that are not detectible with
normal automatic operation.
NOTE: If you have the OSCOR PC Interface software, the signal database should
be permanently stored on computer disk for future comparison. Then, every signal
should be labeled as either a DECLARE (meaning declared threat) or a FRIENDLY.
15. Use the triangulate and locate option or the locator probe to locate confirmed
threats. (Do not remove threats! The proper authorities, those who will determine
the proper course of action, should conduct this procedure.
16. Allow the OSCOR to continue monitoring your environment after all signal
verification is completed.
Loading a Friendly Database
The Load Friendly automatic operation will store signals with constant carrier frequencies
as a friendly signal (see page 80).
In the Load Friendly mode, the OSCOR stores a friendly reference spectrum trace as well
as individual signals that are common to the ambient environment (see page 80). This
should be done at least 1/2 mile (.8 km) from the building to prevent accidentally storing
a threat as a friendly signal.
