Scope and Purpose The purpose of this manual is to verify functionality of the DVX-750 VHF Nav/Com radio before installation into a host PFD chassis. End user operation of the DVX-750 is defined by the user I/O devices and displays that are provided by the host chassis. Therefore, this is not a “User’s Manual” for the end user (customer), but provides some direction for those who need to operate the DVX-750 module “stand-alone” during development, certification, production, or repair activities. 2. Configuration of the DVX-740/750 Module The DVX-750 top level module, Part# 710-00060-( ), consists of metal and mechanical parts as captured in the top level part as well as the following internal boards: a. RF Board, 320-00116-( ) b. DSP Board, 320-00115-( ) The DVX-740 is the same module but with the Marker Beacon receiver disabled on the RF Board. There are no changes to the Digital Board. The BNC connector for the Marker Beacon receiver is installed, so the external connection of the module thru the rear panel of the chassis is the same with either configuration.

Installation steps are simply seating the unit in the cardguides and ensuring that the backplane connector is engaged, then tightening the Allen head retainer screws. After the rear panel is installed on the chassis the BNC retainer nuts with star washers must be installed.

Specification of the DVX-740/750 Module The DVX-750 VHF radio module operates as an airborne VHF COMM transceiver allowing a flight crew to aurally communicate with Air Traffic Control (ATC), other ground stations, or different aircraft in the VHF aeronautical band. It also operates as an airborne ILS/VOR receiver for radio aided navigation and guidance. The DVX-750 must be hosted by a PFD (Primary Flight Display) chassis, which provides conditioned DC power and digital interface to control radio functions. In ILS mode the VHF radio estimates own aircraft horizontal and vertical deviation from the selected ILS localizer and glide paths. In VOR mode it estimates own aircraft bearing to the selected VOR ground station relative to magnetic north (at the station). In addition, any speech or identification audio signals are presented aurally to the flight crew. The DVX-750 radio can also operate as an airborne Marker Beacon receiver and provides some Audio Panel functionality allowing it to interface to headsets (microphone and headphones), a cabin speaker and a transmitter key without requiring and audio panel.

Revision: -00 Date:6/13/2006 Page 1 of 9 Circuit Description and Theory of Operation NOTE: Refer to Block Diagram (Fig 4.1) and circuit schematics during the following description. The DVX-750 VHF radio module operates as an airborne VHF COMM transceiver allowing a flight crew to aurally communicate with Air Traffic Control (ATC), other ground stations, or different aircraft in the VHF aeronautical band. It also operates as an airborne ILS/VOR receiver for radio aided navigation and guidance. The DVX-750 must be hosted by a PFD (Primary Flight Display) chassis, which provides conditioned DC power and digital interface to control radio functions. The DVX-750 consists of two internal printed circuit boards, the “RF Board” (Part# 310-00116-00x) and the “Digital Board” (Part# 310-00115-00x). The concept is to for analog signal processing to occur on the RF board and digital processing to be performed on the Digital Board. The choice was made to do the analog-to-digital conversions on the Digital board with carefully matched analog differential signals interfacing between the two boards thru a 50- mil pitch stacking connector. The transmitted signal is generated digitally and converted to analog on the Digital board and sent to the RF board, while the received signals, which represent the entire operational radio band for each receiver, are fed into the Digital board as differential analog signals and immediately converted to digital format to be channelized and demodulated by the digital downconverter and signal processor. While there can only be one transmitted signal at a time, there can be as many as eight receivers operating simultaneously. Note that nothing changes on the RF board when a receiver frequency is changed, since the entire radio band is fed into the Digital board. The receivers are identified as: Nav Rcvr – Tuned to condition and pass only the 108Mhz to 118Mhz Localizer and VOR Navigation bands such that the digitizer on the Digital board can undersample the RF signal without Nyquist alias signals appearing from out-of-band interference. The analog circuitry on the RF board provides the necessary filtering of signals that would appear in the Nyquist bands, and it applies the gain needed to optimize sensitivity based on signal strength of the in-band signals.. Glideslope Rcvr – Tuned to pass the 326 to 335 Mhz Glideslope signal band, it also provides sufficient filtering to allow the digitizer to undersample the received RF without causing Nyquist alias responses from out-of-band interference. Marker Beacon Rcvr – Very tightly tuned to pass only a single channel at 75Mhz, this receiver includes a custom crystal filter and also allows undersampling of the RF signal. Comm Rcvr – Tuned to pass only the 118 to 137Mhz VHF aeronautical band, this receiver interfaces to a T/R switch, allowing it to share the same antenna with the 16W DVX-740/750 VHF Nav/Com Circuit Description Error!
