includes the desired frequency span. The table below provides some examples
and recommended search span for speed and accuracy.
Example of a Desired Frequency
Span:
Recommended Implementation:
4 – 6GHz 3 – 9GHz (MDCA-1 & MDCB-1/OSCOR 5.0)
6 – 8GHz 3 – 9GHz (MDCA-1 & MDCB-1/OSCOR 5.0)
5.7 – 5.9GHz 5.8 GHz, 250MHz span
8 – 10GHz 3 – 21GHz (MDCA-all & MDCB-all/OSCOR 5.0)
13 – 16GHz 3 – 21GHz (MDCA-all & MDCB-all/OSCOR 5.0)

Storing a Signal in the MDC Frequency Range
When a signal is stored in the OSCOR signal database, only the signal frequency is
stored in OSCOR memory. However, when the OSCOR tunes to a specific signal in the
MDC frequency band (3 - 21GHz) then the OSCOR automatically directs the MDC to the
proper antenna band and filter group to maximize the signal to noise ratio and maximize
the system performance. An example signal is shown below, Figure 11.
Figure 11: ANALYZE MODE USING THE MDC (OSCOR 4.0)
To store a specific frequency:
1. Ensure that the OSCOR is in the ANALYZE mode.
2. Type in the desired center frequency between 3 and 21 GHz (or 3 and 9GHz for the
MDC-900).
3. Press the STORE button.
4. To review the stored frequencies, simply press the RECALL button from ANALYZE
mode. Alternatively, you may select AUTO/MANUAL, then MANAGE DATA, then
SIGNALS, then EDIT MENU and pick from that list.
Note: Frequencies are stored in a 2.5MHz wide window (span). If a different span is
desired the frequency should be stored as a span. See previous instructions. Further
details can be found in the OSCOR Owner’s Guide.
