Figure 2: ILLUSTRATION OF THE MDC-2100 DOWNCONVERSION PROCESS
The OSCOR (version 5.0) displays up to six 1.5GHz (1500MHz) windows simultaneously,
or the spectrum may be separated into three antenna frequency bands: 3 to 9GHz, 9 to
15GHz, or 15 to 21GHz with two 1.5GHz windows displayed simultaneously.
Note: The MDC-900 has a single antenna and covers the band from 3 to 9GHz.
Built-in microwave filters can reduce the display even further. These filters are referred to
as Filter A and Filter B. The Identify function allows for the determination of the
frequency. Below is a chart representing the display of the frequencies in response to the
selected antenna and microwave filter. Understanding Figure 3 is critical to
understanding the OSCOR operations using the MDC-2100 and MDC-900.
Note: The OSCOR always super-imposes the various 1.5GHz windows.
