SECTION 3: OSCOR MANUAL OPERATION
REI OSC-5000E 34
The paragraphs below describe these display modes in greater detail.
Friendly Trace Display
Prior to conducting a sweep, it is highly recommended that the OSCOR be taken out of
the sweep environment and a Friendly Trace be loaded into memory. This provides a
stored image of the frequency spectrum in known and safe location. It is suggested that
this be done at least ½ mile from the sweep location. Note: The Automatic Mode “LOAD
FRIENDLY” process loads this Friendly Trace data as well as storing individual signals.
This Friendly Trace is then utilized to compare to the Real-time or Peak Trace data to
quickly identify signals that are unique to one environment.
To Capture Friendly Trace data:
1. Ensure that the OSCOR is in the Sweep Mode.
2. Press the MENU button (labeled CONFIG).
3. Press the F4 button (labeled MANAGE TRACES).
4. Press the F1 button (labeled ‘Capture Friendly’).
5. To stop or cancel the Capture Friendly spectrum, press the AUTO/MANUAL
button.
NOTE: Capturing the Friendly Trace Data actually initiates automatic mode Load Friendly
operation. (See Page 80 Step 3 Load Friendly Database) The OSCOR will capture
Friendly trace data for all of the inputs that are selected for automatic operation, but the
OSCOR will not create a signal database.
To Display the Friendly Trace data:
1. Ensure that the OSCOR is in the Sweep Mode.
2. Press the MENU button (labeled CONFIG).
3. Press the F1 button repeatedly until the label reads “TRACE 1 FRIENDLY” or press
the F2 button repeatedly until the label reads “TRACE 2 FRIENDLY”. You may
also capture friendly from the Auto Mode “Loading Friendly”.
To Clear the Friendly Trace data:
1. Ensure that the OSCOR is in the Sweep Mode.
2. Press the MENU button (labeled CONFIG).
3. Press the F4 button (labeled MANAGE IMAGES).
4. Press the F3 button (labeled ‘Clear Comparison Span Memory “FRIENDLY”).
5. Press the F1 button (labeled DELETE) to confirm deletion.
Peak Trace Display
Many RF signals only transmit at random times and are therefore very difficult to detect.
These types of signals include pagers, cellular phones, police and aircraft radios, etc.,
Sophisticated bugs that do not stay on the same frequency for very long or only transmit
at certain intervals are very difficult to locate. These signals may be Frequency Hopping,
Spread Spectrum, or Burst Bugs. For this reason, the OSCOR was designed with a Peak
