Strata RX
Operator’s Guide/Tech Ref Manual
2.3.1 Strata RXU
The RXU will always contain an RF front end and switchable IF
filters, and in addition may contain one of the following:
• an analog demodulator, either NTSC or PAL (but not both)
• a digital demodulator with COFDM and/or MPEG.
When a demodulator (either analog or digital) is installed in the
RXU, no demodulator can be installed in the RCU.
2.3.2 Strata RCU
The RCU will always contain a demodulator, either analog or
digital. The options are:
• an analog demodulator, either NTSC or PAL (but not both)
• a digital demodulator with COFDM and/or MPEG
• both analog and digital demodulators.
When the RCU is part of the RX System, the RXU cannot also
have a demodulator installed.
An RCU is used when:
• your usage requires the antenna and the RF front end (in
the RXU) to be separated from the operating location (the
RCU)
• you need to be able to switch between analog and digital
operation.
If your RXU or RCU contains a digital demodulator, it provides
the following additional features:
• a wayside data channel, capable of data rates from 1200
to 38,400 baud
• a configurable Monitor output, which can provide either 70
MHz or ASI output

Audio Connector
If your RXU or RCU is equipped with a demodulator (either
analog or digital), there will be an audio connector installed.
Available on this 10-pin connector are the analog or digital audio
channels, depending on how your radio is configured.
