SECTION 4.6: LIST OF TERMS
This section defines some of the terms that are used in Nautel documentation.
AES/EBU.
Audio Engineering Society/European Broadcasting Union (AES/EBU) is the name of a digital
audio transfer standard. The AES/EBU digital interface is usually implemented using 3-pin XLR
connectors (the same type connector used in professional micros). One cable carries both left-channel
and right-channel audio data to the receiving device.
AUI.
The Advanced User Interface is the advanced remote control/monitoring feature that allows for
extensive remote control and monitoring of the transmitter.
Cutback.
A reduction in RF output power, caused by the occurrence of multiple shutbacks within a
pre-defined period.
DHCP.
Dynamic Host Carrier Protocol.
DSP.
Digital Signal Processing.
EEPROM.
Electrically Erasable Programmable Read-Only Memory.
Foldback.
A reduction in RF output power, caused by adverse load conditions (high VSWR). No
shutbacks or cutbacks have occurred.
LED.
Light Emitting Diode (also referred to as lamp).
LVPS.
Low Voltage Power Supply. A module or modules used in the ac-dc power stage that generates
the low level dc supply voltage for the transmitter.
Preset.
A setting that controls power level, frequency and audio parameters. The GV30N allows you to
pre-program multiple presets.
PWB.
Printed Wiring Board.
Shutback.
A complete, but temporary loss of RF output power, caused by any one of a variety of
faults, including high VSWR, high reject load power, RF drive failure, or an open external interlock.
Shutdown.
A complete and permanent loss of RF output power. Typically follows repeated cutback,
foldback or shutback events.
Surge protection panel.
An electrical panel that protects equipment from electrical surges in the ac
power supply, antenna or site ground caused by lightning strikes.
UI.
The User Interface is the front panel LCD screen that allows for extensive local control and
monitoring of the transmitter.
VSWR.
Voltage standing wave ratio. This is an expression of the ratio of reverse voltage to forward
voltage on the feedline and antenna system. An ideal VSWR of 1:1 provides maximum transmitter-
antenna efficiency.
