The Advanced User Interface is the 17-inch front panel that allows for extensive control andmonitoring 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 transmitter not acheiving the desired set pointpower level (typically this is related to high VSWR).HD Radio. High Definition (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 FMradio channels.Intermediate Power Amplifier (IPA). Refers to circuitry within the transmitter’s RF powermodules which amplifies the exciter's RF output to a level sufficient to drive the final RF amplifiers.LED. Light Emitting Diode (also referred to as lamp).LUT. Look-Up Table.MER. Modulation Error Ratio. This ratio quantifies (in decibels) the performance of a digital radiotransmitter.OFDM.
