There are five relays for failure monitoring (four alarms and one summary

alarm). The operator can define (using the Alarm Menu pages) which alarm

conditions drive the relays. This is described in Chapter 5, Alarms and

Annex C, Menus.

1.3 The Satellite Receiver

1.3.1 Typical Satellite System

The IRD Satellite Receivers are components of the MPEG-2/DVB compliant

range of TANDBERG Television equipment. They are designed for use by

broadcasters and distributors of video, audio and data Services over

satellite.

1.3.2 Input Connections

The Satellite Receiver interfaces directly to Low-Noise Block (LNB) and

accepts an intermediate frequency (IF) input in the band 950 - 2150 MHz

(L-band) for operation in the specified symbol-rate range (see Annex B,

Technical Specification). The unit can provide dc power and polarisation

switching to the LNB.
