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 microphones). One cable carries both
left-channel and right-channel audio data to the receiving device.

ARM.

Advanced RISC (Reduced Instruction Set Computer) Machine. The specific ARM used in VS

transmitters is ARM926, and is used for remote AUI functionality.

AUI.

The Advanced User Interface is the web interface that allows for extensive 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.

Cycling ac power.

Turning off (disabling), then turning on (enabling) the ac power source.

DHCP.

Dynamic Host Carrier Protocol.

DSP.

Digital Signal Processing. Used for transmitter control and 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.

HD Radio.

HD Radio is another term for In-Band-On-Channel (IBOC) technology. HD Radio is a

trademark of iBiquity Digital Corporation.

IBOC.

Nautel In-Band-On-Channel technology provides high quality digital audio over existing FM

radio channels.

Intermediate Power Amplifier (IPA).

Refers to circuitry within the transmitter that amplifies the

exciter's RF output to a level sufficient to drive the final RF amplifiers.

Latching alarm.

An alarm that, while active, keeps the transmitter in an ‘RF inhibited’ state. This

type of alarm (e.g., High SWR Shutdown) require a reset - via the front panel or remote AUI - to
attempt to restore transmitter operation.
