SECTION 4: OSCOR AUTOMATIC OPERATION

OSC-5000E
Deep Dig - the frequency span will be swept at slow pace because the squelch
level is set very low and even very weak signals are analyzed. This mode
may also detect many “false” signals that are nothing more than deceptive
noise signals.
Trace – directs the OSCOR to update the trace data for this span, but it does not
search and log individual signals.
It is important to note that most bugging signals will be somewhat powerful if you are in
the room in which the bug is located. Therefore, most bugs can be found using FastSkim
or MedHunt. Therefore, if you use MedHunt, the unit first makes a pass using FastSkim in
hopes that bug is reasonably strong signal and you will find the bug very fast. For the
same reason, if you use Deep Dig, the unit automatically goes through FastSkim and
MedHunt first to quickly find the bugs before the unit gets into the long and slow process
of Deep Dig.
To select the sweep inputs:
1. Go to the Input spans menu as described above in Figure 49.
2. Use the UP/DOWN buttons to select the desired sweep span.
3. Press the F1 button multiple times to select the desired automatic squelch setting.
To delete or reset the sweep span Inputs:
1. In the sweep span list display, Press F4 labeled “EDIT AS A GROUP”
2. In the Reset/Delete Menu:
F1 - Resets all spans to a desired level.
F2 - Resets all spans to factory defaults.
F3 – Turns the attenuator On or Off for all spans.
F4 - Erases all manually stored spans, but retains default inputs.
NOTE
: Sweep time is largely dependent on the number of signals in the ambient
environment and the settings on the Correlate Mode (see page 78 Correlate: Acoustic
Correlator System (Automatic)).
The Deep Dig Mode is the most reliable method of detecting low power signals, but it
has the slowest sweep time and may detect false signals (bumps in the noise). If the
OSCOR is to be used for a very thorough sweep, the Deep Dig Mode should be used.
However, most bugs that have sufficient power to reach a receiving station within 50
