NV30LT-N OPERATIONS & MAINTENANCE MANUAL LIST OF TERMSVERSION 0.1 2015-03-01 PAGE 3.5.1SECTION 3.5: LIST OF TERMSThis 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 digitalaudio transfer standard. The AES/EBU digital interface is usually implemented using 3-pin XLRconnectors (the same type connector used in professional micros). One cable carries both left-channeland right-channel audio data to the receiving device.AUI. The Advanced User Interface is the advanced remote control/monitoring feature that allows forextensive remote control and monitoring of the transmitter.Cutback. A reduction in RF output power, caused by the occurrence of multiple shutbacks within apre-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). Noshutbacks 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 generatesthe low level dc supply voltage for the transmitter.Preset. A setting that controls power level, frequency and audio parameters. The NV30LT-N allows youto 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 offaults, 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 acpower 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 andmonitoring of the transmitter.VSWR. Voltage standing wave ratio. This is an expression of the ratio of reverse voltage to forwardvoltage on the feedline and antenna system. An ideal VSWR of 1:1 provides maximum transmitter-antenna efficiency.
