The following are general safety precautions that are unrelated to specific procedures and therefore do not appear
elsewhere in this publication. These are recommended precautions that personnel should understand and apply
during through the many phases of operation and maintenance.
ELECTROSTATIC SENSITIVE DEVICES PRECAUTIONS
Since most modules used in all models of equipment have Electrostatic Discharge (ESD) sensitive devices included
in them, all modules should be considered sensitive to electrostatic discharge. Handling in the field shall be the
same as in the factory. Each system is shipped with a wrist strap that must be worn while maintaining the
equipment. The wrist strap shall be fastened to the equipment chassis either in the designated plug-in or attached to
the equipment chassis with the alligator clip. The wrist strap must be used before any modules are removed from
the equipment and at all times while handling the modules until they are placed in a protective environment such as
an anti-static bag. Modules or boards must not be placed on any non-conducting surface such as wooden work
benches, painted metal work benches, plastics, or technical manuals. Any work surface to be used must have a
conducting mat placed on it and attached to earth ground. The mat and additional wrist straps can be obtained from
SELEX Sistemi Integrati Inc.
KEEP AWAY FROM LIVE CIRCUITS
Operating personnel must at all times observe all safety regulations. Under no circumstances should any person
remove any protective covers that expose lethal voltages. Do not replace components or make adjustments inside
the equipment with primary power supply turned on. Under certain conditions, dangerous potentials may exist when
the power is in the off position, due to charges retained by capacitors. To avoid casualties, always remove power
and allow time for the capacitors to discharge before touching it.
DO NOT SERVICE OR ADJUST ALONE
Under no circumstances should any person reach into or enter the enclosure for the purpose of servicing or adjusting
the equipment except in the presence of someone who is capable of rendering aid.
RESUSCITATION
Personnel working with or near high voltages should be familiar with modern methods of resuscitation.

MANUFACTURER’S WARRANTY
SELEX Sistemi Integrati Inc.
The following warranty is applicable in all cases, except where modified or superseded by specific contract terms.
Contact SELEX Sistemi Integrati Inc. if clarification is required.
A. The Manufacturer warrants to the original Purchaser, subject to the limitations and exclusions stated below,
that mechanical and electrical parts of products which it manufactures, (the “Products” will be free of
defects in materials and workmanship for a period of (I) one (1) year from the date of installation or (ii) 18
months from the date of shipment, whichever first occurs (the “Warranty Period”).
B. If the Customer believes a Product is defective, notice thereof shall be provided to the Manufacturer’s
Customer Service Department at the address provided on the cover page and (if applicable) to the selling
distributor. A defect in material and workmanship covered by this warranty shall be deemed to have
occurred only if, and as of the time when, the Manufacturer is notified in writing by the Customer, within
the Warranty Period, that the Product has become defective, and the Manufacturer’s personnel verify that
the said Product, in fact, does not comply with the warranty provided hereunder and it is determined that:
(i) The Products, during the entire Warranty Period, have been operated within normal service
conditions, recommended by the Manufacturer and recognized in the industry, and
(ii) The Products have been installed and adjusted according to the Manufacturer’s procedures as
stated in the Instruction Manual or other instructions supplied in writing by the Manufacturer.
C. Failures caused by lightning or other acts of God, or power surges, are not considered to be defects in
materials and workmanship and are not covered under this warranty. Routine Maintenance and calibration
are also not considered to be defects in materials and workmanship and are not covered under this
warranty. Any change, modification or alteration of the Manufacturer’s Products not specifically
authorized by the Manufacturer will void this warranty.
D. If it is determined that the conditions for warranty coverage, as described above, have been satisfied, the
Manufacturer shall repair or replace the defective products or parts thereof in accordance with the
following procedures:
(i) Customer will contact the Manufacturer’s customer Service Department which will issue the
Customer a Return Authorization (RA) number.
(ii) The Component, defective part, or Product, as appropriate, shall be returned to the Manufacturer
for inspection, freight prepaid by the customer. The Component, defective part, or Product MUST
be packaged with an industry standard anti-static protective bag sufficient to prevent any ESD
intrusion during handling and shipment, and MUST ALSO be packaged to protect from damage
due to rough handling encountered during shipment. FAILURE TO COMPLY WITH THIS
REQUIREMENT WILL VOID THE WARRANTY OF THE RETURNED ITEM. The RA
number must be clearly displayed on the exterior of the shipping container. No shipments will be
accepted without a RA number. All custom duties, fees, etc. will be paid by the Customer.
(iii) If, upon inspection it is determined by Manufacturer’s personnel that the Product or component
thereof is indeed defective and covered by this warranty, then Manufacturer, at its option, may
either repair the Product or defective components thereof and return the same to the Customer or
ship a replacement for the defective Product or part thereof, freight paid. All customs duties, fees,
etc. will be paid by the Customer. The Product or component thereof will be returned to the

EQUIPMENT DESCRIPTION
1.2
The DVOR system provides a reference from which aircraft bearing can be determined. To do this, a carrier is
radiated in the 108 to 118 MHz band and modulated by two 30 Hz signals. One amplitude modulates and the other
frequency modulates (also called the reference phase and variable phase signals, respectively) the carrier signal.
This is done in such a way that the phase difference of the 30 Hz signals varies degree for degree with the magnetic
bearing around the VOR station.
The DVOR system consists of one electronics cabinet with sub-assemblies, a Portable Maintenance Data Terminal
(PMDT), one reference (carrier) antenna and 48 sideband antennas installed on a counterpoise, one field monitor
antenna, and interconnecting cables.
The DVOR electronics cabinet standard configuration uses convection cooling. No fans or blowers are installed in
the cabinet.
Electronics Cabinet
1.2.1
The 1150A VOR is contained in one (1) electronics cabinet measuring 24" wide, 24" deep and 72" high. It utilizes a
standard 19" rack configuration with a front panel door that covers and protects the equipment. The Model 1150A is
100% solid-state. Its internal circuitry is contained on plug-in type printed circuit card assemblies (CCAs) and RF
modules.
Refer to Figure 1-3 through Figure 1-6 whichshow the layout of the various modules within the Model 1150A
VOR cabinet. The paragraphs on the following pages provide a brief description of each of the modules and
its function in the system. Note that the cabinets shown are dual equipment systems. Refer to Figure 2-2 and
Figure 2-3 for the Model 1150A Doppler VOR system block diagram.

Model 1150A DVOR
1.2.1.1
Local Control Unit (LCU) (1A1)
The Local Control Unit (LCU) is located in the upper portion of the VOR cabinet and provides station status
information. The LCU provides for Transmitter, Monitor and System setup, monitoring and control. Alarm
indication from the VOR Monitors initiates transfer or VOR shutdown.
1.2.1.2
Synthesizer Assembly (1A3A1, 1A3A11)
The Synthesizer assembly generates three RF signals (carrier, upper and lower sidebands) for the VOR transmitter.
There are three boards in the Synthesizer Assembly. The Carrier board provides the carrier frequency and phase
control capability for the Carrier Amplifier. The sideband board generates upper and lower sideband frequencies for
the Sideband Amplifier Assemblies. The third board (Interface) provides connectivity to the backplane and includes
digital interface circuitry to the Audio Generator and RMS processors.
1.2.1.3
Audio Generator CCA (1A3A2, 1A3A9)
The Audio Generator CCA is responsible for developing and controlling the audio signals, generating the carrier
modulation signals and monitoring and controlling RF power level and phase control signals used in the DVOR. In
addition, DC analog voltages representing different modulation and power levels of the DVOR RF signals are
applied to, and analyzed by, the audio generator to determine carrier power levels, carrier percent modulation,
sideband power levels and VSWR. An on-board micro controller and memory circuitry controls all functions within
the CCA and communication through the serial connection to the RMS CCA.

1.2.1.4
Monitor CCA (1A3A3, 1A3A10)
The Monitor CCA amplifies the RF input from the field monitor antenna, then band pass filters and analyzes the
signals. The parametric data is displayed on the PMDT and the Monitor CCA initiates an alarm status indication to
the LCU if the DVOR fails to operate within specified limits.
1.2.1.5
Low Voltage Power Supply (LVPS) CCA (1A3A4, 1A3A8)
There are two LVPS assemblies used in the transmitter cabinet. LVPS 1A3A4 is the low voltage power supply for
transmitter 1 and 1A3A8 is the LVPS for transmitter 2. Each LVPS is identical in construction and operation. Each
is interchangeable with the other.
1.2.1.6
Test Generator CCA (1A3A5)
The Test generator CCA performs two functions. Its primary function is to provide a standard reference signal to
the DVOR monitors for calibration whenever directed by the RMS CPU for monitor integrity testing.
The secondary function is an operator maintenance function, which allows test signals to be sent to the monitor(s),
as directed by an operator through the PMDT. The operator can vary signal parameters (i.e., voice band audio
frequency, percent modulation, phase shift, etc.) to determine if a monitor is functioning properly and will alarm at
the required settings.
1.2.1.7
Remote Monitoring System (RMS) Processor CCA ( 1A3A6)
The Remote Monitoring System (RMS) Processor CCA controls the transmitter and monitoring systems. The RMS
CCA performs communications via thirteen serial ports plus a parallel port, and facilitates monitoring/control in a
single or dual VOR system. The RMS CCA receives battery-backed DC power from the BCPS.
The RMS CPU contains a micro controller, RAM, EPROM, EEPROM, bus control and power monitor circuitry. It
processes the system status, directs communications with the outside world, and communicates with the DVOR
monitor and audio generator assemblies.
1.2.1.8
Facilities CCA (1A3A7)
The Facilities CCA provides system I/O for the Remote Monitoring System CCA. Many of the inputs and outputs of
the Facilities CCA eventually connect to the Interface CCA after routing through the Control Backplane CCA.
System battery-backed power supplies (nominally 48VDC) enter and are regulated down into several lower
voltages; including +24V, ±15VDC, ±12VDC, +5VDC, and +3.3VDC.
The Sideband Amplifier Assemblies are located in the middle rack (1A4) of the DVOR cabinet. Each Sideband
Amplifier contains one CCA and generates two separate RF signals. Both signals are either above the carrier
frequency or below the carrier frequency by 9960 Hz.
1.2.1.10
RF Monitor Assembly (1A4A4)
The RF Monitor assembly is located in the middle rack (1A4) of the DVOR cabinet. The RF monitor assembly
functions as an RF detector/amplifier and distributor of the detected RF signals. The RF monitor assembly has a
high power dummy load for the carrier mounted to a heat sink that is attached to the assembly chassis. There are
four sideband dummy loads.
1.2.1.11
Commutator Control CCA (1A4A5)
The Commutator Control CCA connects to a 25 conductor cable on the backplane CCA. This cable
originates from one of the two Audio Generators in the Control rack. The output of the Commutator
Control CCA exits onto the backplane and to two 40-pin connectors that connect to ribbon cable from the
Commutator CCAs.
Capability for the ground performance check of the antennas and commutator switching is provided. This check is
automatic after it has been started by the technician and therefore is called an Automatic Ground Check system.
When started, the Monitor CCA sends a switch position code to the Commutator control CCA via the 25-pin cable
originating at the Control rack.

1-7
Model 1150A DVOR
The switch positions start at 0 and increment by one until 15. Each position represents 22.5 degrees of antenna
rotation from the nominal position. At each position the Monitor CCA determines the azimuth angle at the Field
Monitor antenna location. From this data the errors are measured and a Fourier Analysis is performed to generate
the display data.
The error as determined during the ground check is analyzed to determine the bias, the duantal error, quadrantal
error and octantal error. The bias error is the average error around the station. The duantal error is sinusoidal with a
rate of one cycle in the 360 degrees around the station. The quandrantal error is sinusoidal with a rate of two cycles
in the 360 degrees around the station. The octantal error is sinusoidal with a rate of four cycles in the 360 degrees
around the station
A 4-pin header on the Commutator Control CCA may be strapped to enable/disable the DVOR automatic groundcheck as desired.
WARNING
Enabling the automatic ground-check test changes the signal in space and will cause unsafe
conditions for aircraft. A notice to airmen (NOTAM) must be issued prior to starting this
1.2.1.12
Battery Charging Power Supply (BCPS) Assembly (1A5A1, 1A5A2)
The BCPS assemblies provide regulated voltage to the transmitter from either the AC input or the batteries. The
BCPS assemblies are located in the third rack. The AC voltage is an input to the BCPS which converts to
approximately 50 Volts DC. The BCPS assemblies are also responsible for charging the batteries when AC is
present.
1.2.1.13
Carrier Power Amplifier Assembly (1A5A3, 1A5A4)
The Carrier Amplifier has one assembly. The Carrier Amplifier circuit card assembly, which is also the module’s
I/O, processes the control signals from the Audio Generator to properly control the desired output RF modulation
and amplitude. This assembly is capable of providing 100 Watts or more of Carrier power at up to 80% AM
modulation.
1.2.1.14
Interface CCA (1A9)
The Interface CCA provides interface connections between the RMS/Facilities/Control Backplane CCAs and the
outside world. Examples include spare analog and digital inputs, spare digital outputs, temperature sensors, smoke
detector, and intrusion sensor. RS232 communications are provided to RCSU and PMDT terminals as well as an
Ethernet module. All signals are protected by transient voltage suppression (TVS) devices on the Interface CCA
before exiting.
1.2.1.15
AC Power Monitor Assembly (1A6)
The AC Power Monitor CCA provides a means for the VOR system to measure the AC current and voltage levels of
the obstruction lights and of the VOR system itself. Provision for operating with a photo switch is incorporated. A
capability to bypass the photo switch for the obstruction lights is provided.
1.2.1.16
Commutator CCA (1A10, 1A11)
Each commutator CCA measures 15-7/8" high and 14-7/8" wide. There are two commutator CCAs installed in the
top of the electronics cabinet. They are located on the upper left and upper right side and may be accessed by
removing the cabinet side panels. The right (viewed from the front) commutator CCA is used to switch the RF
signals to all the odd antennas, and the left commutator CCA drives the even antennas. Each commutator has
twenty-six N type RF connectors and two 37-pin D-shell connectors.
Portable Maintenance Data Terminal (PMDT)
1.2.2
The standard PMDT consists of a laptop computer and is the input/output device for controlling and communicating
with the DVOR system. Station control, adjustment and monitoring functions are available through the computer,
and are accessed via a Windows-based operator interface. An optional external mouse may be used with the laptop
computer for ease in operation. An optional desktop PC is available as a substitute for the standard laptop computer.
Also, an optional printer is available for use with either the laptop or desktop PC.

Model 1150A DVOR
Station security control is provided through a three-level password system. Complete access to the system for
djustments and measurements is provided at level 3. Modification of non-critical parameters is available at level 2,
a
and read-only access is available at level 1.
All functions available on the local PMDT are available remotely via a modem and dial-up telephone line to an
optional remote laptop or desktop PC running the PMDT software. Refer to Section 3 on the use of the PMDT.
Transmitting Antenna System
1.2.3
The DVOR antenna system consists of a single carrier antenna assembly at the center of the counterpoise, and 48
sideband antenna assemblies spaced equally in a 44' diameter circle concentric with the carrier antenna assembly.
All antennas are enclosed in small, weatherproof, fiberglass radomes.
1.2.3.1
Carrier Antenna
Refer to Figure 1-7. Carrier Antenna is a single Alford loop on a support plate. The antenna is supported above the
counterpoise by a metal pedestal. This antenna is electrically tuned to the station frequency by means of two large,
air-dielectric capacitors. This antenna is designed to function with a collocated distance measuring equipment
(DME) or tactical air navigation (TACAN) antenna system. When required, a metal pipe passes through the center
of the support plate and center of the antenna. The pipe serves as a conduit for feed lines and cables to a DME or
TACAN antenna and obstruction lights, when installed. When collocated with a TACAN, the antenna is enclosed
within a larger fiberglass shelter called a “walk in” radome. Figure 1-8 depicts the carrier antenna provided for use
without collocated DME or TACAN antennas. The hole through the center is not present and the radome and
pedestal are the same as the sideband antennas.
