2.1 Chapter Overview
This chapter provides an overall description of the Strata RX, its
components, and its capabilities.
Here are the topics covered:
2.2 System Description
The Strata RX is a highly capable, compact microwave receiver
system. The RX System is composed of the RXU Receiver Unit
and the RCU Receiver Control Unit. This modular architecture
allows you the maximum flexibility in configuration, siting, and

operation.
RF and demodulation functions are split between the RXU and
RCU, according to your needs. See the descriptions below and
the configurations illustrated in Section 2.5 on page 2-6.
2.2.1 RF and Demodulation Options
Bands
The RX System can be ordered configured for any one
of several RF bands. In addition, selected combinations of band
segments are available in a two-band version. We are constantly
working to expand and upgrade the capabilities of the RX
System. Consult your Sales Representative or contact the
factory for the latest band availability.
RF/IF Only
If you are integrating the RX System into existing
equipment and need only the RF front end, your RX System will
have only an RXU. The RXU will contain all the RF amplifiers
and downconvertors, and provides a 70 MHz IF output for an
external demodulator. The RXU also incorporates switchable IF
filtering, with settings optimized for either analog or digital
signals.
RF + Analog Demodulation
If you need both RF and
analog
demodulation functions, you can choose one of two solutions:
• Standalone RXU
- The RXU contains the RF front end, switchable IF
filters, and either an NTSC or PAL demodulator (but
not both).
- The RXU also contains a Low Pass Filter, which can
be configured to be in or out of the video signal path.
- The RXU provides either NTSC or PAL composite
video output, with 4 channels of analog audio.
- Ideal for minimizing space and weight.
