OSCOR OSC 5000 - Figure 53 Pre-Programmed Default Input Spans; Input Spans for Automatic Operation

SECTION 4: OSCOR AUTOMATIC OPERATION

Input Spans for Automatic Operation
Unless otherwise specified, the frequency range scanned for each input is the default
span noted in Figure 30 Sweep Span Display. However, alternative frequency spans can
be scanned in the same input band. This allows the user to program multiple frequency
windows within the same input device.
The OSCOR has 6 pre-programmed input frequency spans that include the available
range of the electromagnetic spectrum. The bandwidths used for automatic operation are
covered in the Figure below. Up to 100 additional frequency spans may be in memory.
Additional span or input parameters are described in detail on page 46 Sweep Span
Storage. These stored additional frequency spans can be recalled and/or modified in the
Manual Mode using the normal STORE/RECALL functions.
The following chart shows the pre-programmed (default) inputs and their associated
frequency ranges.
Labeled Input Default Frequency Range
RF LOOP 10 kHz - 510 kHz
WHIP Lo 500 kHz - 5.5 MHz
WHIP Hi 5 MHz - 1505 MHz
DISCONE 1505 MHz - 3005 MHz
MDC 3 GHz – 21 GHz
INFRARED** 10 kHz - 5 MHz
AC VLF* 10 kHz - 5 MHz

*The AC VLF Mode checks the power cord for carrier current signal. The AC power cord
can be plugged into outlets to check the AC power, or the power cord may be used with
the AC VLF adapter to check any unknown pair of wires.
** The infrared detector receives wavelengths between 850-1050 nm. This covers the
majority of available infrared transmitters.
The Automatic Mode operation contains an automatic squelch level setting. The far-left
column of the sweep span list screen displays the automatic squelch level status for
Automatic Mode operation. The available selections are “Span Off,” “FastSkim”,
“MedHunt”, and “Deep Dig”. These selections automatically control the squelch level
setting of the automatic operation.
Span Off - the frequency span will not be swept in the Automatic Mode.
FastSkim - the frequency span will be swept at a very fast pace because the
squelch threshold is set relatively high and only the stronger signals will be
detected.
MedHunt - the frequency span will be swept at a moderate pace and medium
strength signals will be detected.
