INTRODUCTION
The OSCOR Microwave Downconverter option (MDC-2100) expands the OSCOR ’s
frequency range limit to 21GHz.
The MDC-900 extends the OSCOR ’s range to 9GHz.
Note: General descriptions of the MDC-2100 in this guide may not always include
exceptions for the MDC-900, which does not cover the 9 to 21GHz spans.
Microwave signals tend to be directional; therefore, the MDC-2100 features an array of
high gain directional antennas. The MDC is compatible with the OPC interface and the
OTL locator options. It can function in the sweep, analyze and correlation modes and
includes a tripod, which provides the stability needed to securely point the antennas and a
swivel neck for easy positioning.

The span of frequencies from 3 to 21GHz is so broad the OSCOR cannot display them all
in a single window; therefore, a special folding process is implemented. This process
folds the entire spectrum from 3 to 21GHz into twelve 1.5GHz windows. Six windows may
be viewed simultaneously when using OSCOR 5.0 software. Figure 2 illustrates the
down-conversion process.
