Electrostatic Discharge (ESD)

Electrostatic Discharge (ESD) can severely damage sensitive components located on printed circuit cards. Electrostatic discharge measurements as high as 35,000 volts, can occur from walking across a carpet.

To avoid potential damage to electronic equipment, follow correct electrostatic discharge preventive procedures when handling or working with the hardware.

1. Always wear an electrostatic discharge wrist strap when handling electronic hardware.

2. Connect the electrostatic discharge wrist strap to a reliable earth ground.

3. Replace worn or frayed electrostatic discharge wrist straps and connecting cords.

4. Check your electrostatic discharge strap every month.

5. Do not use electrostatic discharge straps that are out of calibration.

6. Place printed circuit cards in an electrostatic discharge bag or other ESD container to

avoid damage from stray static charge.

7. Do not place printed circuit cards on any surface that is not an approved electrostatic

discharge surface correctly connected to earth ground.

Hazardous Materials

Hazardous materials are likely to be present at the maintenance facility. Many of the following substances are toxic (causing illness or death): flammable materials, explosive materials, corrosive materials that cause the skin or eyes to burn on contact, reactive materials that, when exposed to heat, air, water, or certain other chemicals, can cause burning or release of toxic vapors.

Some hazardous substances are obvious, for example, adhesives, solvents, abrasives, fuels, and pesticides. Other substances are less obvious, for example, toner in office copiers and printers and heavy-duty cleaning and disinfectant products. The list of substances identified as hazardous in the workplace is constantly increasing as new processes and new technologies create new chemicals.

Post a list of hazardous materials in each work area. In the United States, hazardous materials include a material safety data sheet that describes the material, the health/safety risks, correct usage procedures, recommended storage facilities, and the method(s) to treat exposure. If local codes do not require use of a material safety data sheet, a simple list may describe the type of material, correct usage and storage methods, and its hazard(s). Include emergency first aid procedures in the event that personnel experience exposure to the material.

Lockout/Tagout Policy

Lockout/Tagout refers to the complete isolation of equipment during maintenance or service work. It is good practice to require use of locks or tags as warning devices to prevent injuries to service personnel from accidental machine start-ups.

While servicing equipment, place a red or yellow tag on the equipment, indicating it is out of use for repairs or maintenance. Treat these tags as a lockout tag. To obtain information regarding when that piece of equipment will become available for use, contact the person who signed the tag.

Examples of equipment/service to tag/lock out during servicing include:

Work situations where unexpected application of power or starting of equipment could occur include:

Power types include:

Do not attempt to start, energize, or use a machine or equipment that

is locked out for service or maintenance.

Warnings, Cautions, and Notes

Warnings, cautions, and notes alert the user to special conditions regarding safety or correct performance of a particular step(s).

WARNINGS  Used when a procedure, technique, or restriction could result in injury or death to personnel.

CAUTIONS  Used when a procedure, technique or restriction could result in damage to equipment.

NOTES  Used whenever emphasis or consideration for the performance of a procedural step or steps are necessary.

Some personnel in the work place should be trained in rendering first aid. In those places where high voltages are present, they should be familiar with methods of resuscitation.

Keep Away from Live Circuits

Operating personnel must observe at all times all safety regulations. Do not replace components inside the equipment with the power supply turned on. Under certain conditions, dangerous potentials may exist when the power control is in the off position due to circuit design or charges retained by capacitors.

Chapter I

1.0 General Information

1.1 Scope of Manual

This manual contains information necessary to install, operate, maintain and repair the CU-9150 1 KW Automatic Digital Antenna Coupler.

1.2 General Description

The CU-9150 is a 1000 watt high quality remotely controlled antenna coupler, capable of providing efficient matching of antennas 23 feet and longer to a 50 ohm transmission line, over the frequency range of 1.6 to 30 MHz. In addition, the coupler may be used as a 'line flattener' to correct the VSWR of resonant antennas. The unit is designed as a companion to the Sunair LPA9600 1 kW or LPA-9500 500 Watt Linear Power Amplifiers.

The CU-9150 is designed to operate at separations of up to 250 feet from the Exciter/Transceiver. The coupler control is located on the front panels of Sunair 9000 Series Exciters/Transceivers. Manual tuning cycles are initiated by pressing the CPLR TUNE pushbutton on 9000 Series front panel. A meter for indicating forward and reflected power is also located on the 9000 Series front panel. During a tuning cycle, the linear power amplifier is disabled and tune power (35-45 Watts) is supplied by the Exciter/Transceiver. The operating power and commands to the coupler are also supplied by the Exciter/Transceiver alone. The coupler may be used directly with a 125 watt Exciter/Transceiver if low power operation is desired or the linear amplifier is off-line.

2.4 Power Requirements

All power necessary to operate the CU-9150 1 KW Automatic Digital Coupler is supplied from a companion Exciter/Transceiver via the LPA-9600/LPA-9500 control cable. See Figure 2.11-1 for control cable connections.

2.5 Installation Considerations and Mounting Information

The satisfactory operation of the equipment will depend upon the care and thoroughness taken during the installation.

2.5.1 General Installation Procedures and Requirements

1. Carefully plan radio/amplifier/coupler/antenna locations, observing the following

requirements before starting installation.

2. Provide best possible RF ground for all equipment. Use flat copper strap 1" wide or #6

(or larger) wire and make connections to the ground terminal of all system components. Leads to ground system should be as short as possible.

After the system grounds have been installed, connect the station ground system to the antenna coupler ground terminal. Bear in mind that the antenna ground lead is actually part of the antenna itself, and therefore will have a marked effect on the antenna input impedance. If a 35-foot vertical antenna is to be used, at least 12 separate 35-foot radials connected to a common ground stake are recommended.

2-2 Use or disclosure of information from this document is subject to the restrictions

indicated on the proprietary/confidentiality page of this document.

Page 23

CU-9150

3. Provide the maximum separation between coupler/antenna and the radio with its

associated wiring. 100 feet is the recommended minimum distance and up to 250 feet separation may be used.

4. The antenna lead from the antenna coupler RF output insulator must be insulated for at

least 15 kV potential. As an alternative, copper tubing with an outside diameter of at least 1/4" may be used, provided that it is routed to the antenna terminal so that it is spaced at least six inches from any metal objects in its vicinity. It is important to keep the length of this lead to an absolute minimum since it forms a part of the radiating portion of the antenna. Three (3) feet would be the maximum distance if antenna efficiency is not to be compromised.

5. Linear amplifiers with low level modulation such as used in Sunair exciters/transceivers

will sometimes oscillate if the high RF power level output is radiated or conducted into the low level stages. Evidence of this situation is erratic or excessive power output. This is caused by too close proximity of the coupler output and antenna to the transmitter and/or inadequate RF grounds. Carefully following the above procedures will prevent this from occurring.

2.5.2 Mounting Considerations

See Figure 2.11-2 for Coupler outline dimensions. The mounting position for the CU-9150 is dependent on the available space for mounting. Four

mounting feet with 3/8" wide slots are provided on the coupler. If it is necessary to mount the coupler on a wooden pole, simple angle-iron adapter brackets may easily be fabricated. Since the total weight of the unit is only 45 pounds, two wooden 4 x 4s set in cement would provide dependable support.

2.5.3 Installation of Remote Control and RF Cables

It is recommended that the remote control cable be procured from Sunair. However, if necessary, the cable may be made from individual No. 20 AWG stranded wire with an overall braided shield and PVC jacket. Interconnection cable details are given in Figure 2.11-1.

2.6 Antennas and Ground Systems

2.6.1 General

Sunair Exciters/Transceivers are designed to operate into a 50 Ohm resistive antenna system with a maximum voltage standing wave ratio (VSWR) of 2:1. When used with the CU-9150 1 KW Automatic Digital Antenna Coupler alone or with the LPA-9600 Linear Amplifier, the system will match antennas 35 feet and longer. The CU-9150 is placed close to the antenna (within 3 feet or less) and controlled from the front panel of the exciter/ transceiver. This optimizes both operator convenience and electrical performance. As there are numerous types of antennas, a complete discussion is beyond the scope of this manual; however, some general DOs and DON’Ts of antenna installation are listed below:

 The antenna should be clear of all large objects such as trees and buildings.

Use or disclosure of information from this document is subject to the restrictions 2-3 indicted on the proprietary/confidentiality page of this document.

Page 24

CU-9150

 When using whip antennas, the ground system actually forms part of the radiating

system. Where space permits (such as in a base station installation) a good ground plane or radial system should be installed at the base of the antenna. (See Figure 2.11-3.)

NOTE: An inadequate ground system is most often responsible for

disappointing performance when using a whip antenna.

2.6.2 Random Length Non-Resonant Antennas

See Figure 2.11-3, Figure 2.11-4, and/or Figure 2.11-5 as needed. Whips and longwires are popular non-resonant antennas. The whip antenna is often used in

mobile, marine, portable or semi-portable installations because it is rugged and self-supporting. The antenna impedance is strongly dependent on the operating frequency, and an antenna coupler, therefore, must be used to match the antenna to the transceiver. Thirty-five foot whip antennas offer a good compromise between practical height and good electrical performance at low frequencies. The whip’s performance is greatly influenced by its ground system. For temporary base station installations, a minimum of four 6-foot long ground rods should be driven into the ground, symmetrically placed around the antenna base. The rods should be bonded together with heavy strap and then connected to the antenna coupler ground by another short, heavy strap. If the antenna is mounted on the roof of a building where a short ground lead to coupler cannot be obtained, a minimum of four symmetrically placed ground radials should be installed at the base of the antenna, bonded together, and connected to the antenna coupler ground post. The radials should be made of number 12 gauge wire or larger and should be at least 1/4 wave long at the lowest operating frequency. (Radial length in feet = 246/frequency in MHz.) The whip’s radiation pattern is omni-directional in the azimuthal plane.

The longwire antenna, illustrated in Figure 2.11-5, is a popular base station antenna where a wide range of operating frequencies are used. The antenna impedance varies greatly with frequency and, therefore, must be matched to the transmitter with the antenna coupler. The CU-9150 will efficiently match longwire antennas up to 150 foot in length. The radiation pattern of the longwire antenna is also a strong function of operating frequency. The two most popular longwire antennas, (75 and 150 foot) available from Sunair, exhibit excellent low frequency radiation efficiency.

2.7 Long-Wire Adapter Kit (1A1A5) 8120909003

The Long-Wire Adapter Kit is required for wire antennas between 50 and 150 feet in length. See Figure 2.11-6 for installation details.

Operation using a 23- to 35-foot whip antenna is still possible after installation of the long-wire adapter kit. This is accomplished by changing the point at which the wire from K19 on the chassis (1A1K19) is connected to the long-wire adapter kit. See Figure 2.11-7 for details.

A WHIP / LONG-WIRE identification plate is included with the long-wire adapter kit. It should be secured to the top cover of the coupler by one of the cover hold-down screws. It is meant to indicate whether the long-wire adapter kit is configured for whip or long-wire operation.

Page 25

CU-9150

2.8 TX Only Function

If the coupler is being installed in a system with separate transmit and receive antennas and where two or more transmitters are using collocated antennas, the TX ONLY function should be enabled. When this function is enabled, the coupler opens the RF path between the tuning network and the radio system when the radio system is in receive mode. Therefore, high RF voltages induced by adjacent transmitters are confined to the coupler.

The TX ONLY function is enabled by soldering a jumper wire between E4 and E4 of the 1A1A4A1 RF Detector Board.

2.9 Software Revision

In order for the CU-9150 to function properly, the software revision in the companion transceiver or exciter and linear amplifier must be equal to or later than the following:

Equipment Software Revision

RT-9000 or RT-9000A D4 T-9400 B1 LPA-9500 B1 LPA-9600 B1

2.10 Checks after Installation

Follow steps outlined in Section 3.2 for your particular system configuration.

WARNING - HIGH VOLTAGE

The radio operator and service technician should exercise caution not to contact the ANTENNA INSULATOR E2 output while transmitting.

CHAPTER IV  Theory of Operation

4.0 Theory of Operation

4.1 General

The CU-9150 is a fully digital antenna coupler designed for use with the LPA-9600 1 kW or LPA-9500 500 Watt Linear Power Amplifiers and the Sunair 9000 series Exciters and Transceivers. The coupler is rated for 1000 Watts PEP or average power and will tune common shipboard and ground based antenna systems such as 23 foot and 35 foot verticals or 50 to 150 foot end-fed wire antennas.

A 128 channel non-volatile memory system is provided for use with Transceivers or Exciters providing channel information to the coupler.

Figure 4.9-2 provides an assembly tree of all the major assemblies, their part numbers, and reference designations. Figure 4.9-3 provides a block diagram for the unit. Both are at the end of this section.

4.2 Antenna Impedance Matching Network

The antenna impedance matching network is a lowpass PI and PI-L network depending on the frequency and antenna system employed. The lowpass PI network offers several desirable advantages over high-pass network configurations such as:

 Harmonic Attenuation. 5 to 20 dB depending on the antenna type and operating

frequency.

 Pipeline Operation (Bypass) for Automatic Link Establishment (ALE) receives scan

operation. This technique conserves mechanical relay life.

The PI network can be viewed as two L-networks placed in back-to-back configuration. The PI network is very flexible, it can provide a number of network component solutions for any one impedance matching problem, by modifying the antenna impedance with shunt output capacitance. However, excessive amounts of shunt output capacitance results in a low network impedance, producing significant circulating current in both the series-L and shunt C components. The CU-9150's RF network and tuning algorithm have been carefully designed to use the minimum amount of output capacitance required to achieve a satisfactory network solution. This ensures that the matching network operates at maximum efficiency and reduces electrical stress on the RF network components and relays.

Operation at 5 MHz and above with the specified antennas results in a PI-network solution. When operating below 5 MHz, with electrically short antennas, a large negative reactive component will appear at the antenna terminal. To solve this, additional series inductance is required: three selectable values are included in the network, transforming it to a PI-L. Frequency information is supplied to the coupler via the channel lines.

A block diagram of the CU-9150 is shown in Figure 4.9-3. The input capacitor bank (50 Ohm side), located on the Input Capacitor Assembly, consists of C1 through C11D and provides binary stepped capacitance values from 5.6 pF to 10,233 pF. The L series inductor assembly consists of inductors L1 through L9 providing binary stepped inductance values of 0.025 µH

Use or disclosure of information from this document is subject to the restrictions 4-1 indicated on the proprietary/confidentiality page of this document.

Page 38

CU-9150

through 12.75 µH. The L-out assembly consists of L10 through L12, providing 12.6 µH through 63 µH. The output capacitor bank, consisting of C2 through C6D provides binary stepped capacitance values from 25 pF to 775 pF. Capacitor C1, 15 pF serves as a fixed ballast capacitor.

4.3 Chassis Assembly 1A1

4.3.1 General

The chassis assembly contains the RF network components, Input Connector Assembly 1A1A2, CPU Assembly 1A1A3, RF Detector 1A1A4A1, Input Capacitor Assembly 1A1A4A2 and Mother Board Assembly 1A1A1.

4.4 Input Connector Assembly 1A1A2

4.4.1 General

The Input Connector Assembly serves as the interconnect between the LPA-9600/9500 and 9000 series radio equipment.

4.4.2 Configuration and Operation

The Input Connector Assembly provides T-lowpass RF filters on each of the signal, control and power lines entering and exiting the CU-9150 with the exception of the TX/RX data lines. The TX/RX data lines are used during service or system evaluation and are normally not connected during routine operation. The T-lowpass filters prevent unwanted RF radiation emitted by the antenna matching network from appearing on the control cable and interfering with the companion transceiver or exciter circuitry.

In addition to this protection, each of the aforementioned lines are supplied with Metal Oxide Varistor, transient voltage surge suppressors. The suppressors will minimize transient voltage levels that can appear on any signal, power or control line in the event of a lightning surge.

4.5 CPU Assembly 1A1A3

4.5.1 General

The CPU Assembly contains the system microprocessor, memory, D/A converter and relay drivers.

4.5.2 Microprocessor

The CPU assembly utilizes the 80C188EB (16 bit internal / 8 bit external) microprocessor, U103, operating at an external clock speed of 14.7456 MHz. The 80C188EB contains internal chip select logic, three hardware timers, parallel I/O, and two asynchronous serial I/O channels in single package. Its operating firmware is contained in EPROM (27C010-040), U301. SRAM (TC551001), U302 is used to hold program variables and temporary data such as phase and magnitude discriminator error correction levels. EEPROM (28C64-256), U303 is non-volatile memory used to store channel network solutions.

The 80C188EB controls its associated memory and peripherals using three busses:

4-2 Use or disclosure of information from this document is subject to the restrictions

indicated on the proprietary/confidentiality page of this document.

Page 39

CU-9150

 AD0 through AD7, a multiplexed address/data bus containing either data or address

information.

 A8 through A15, which always contain address information.  The Control/Status bus, which contains signals RD, WR, IO/M, and ALE.

4.5.3 Serial Communication

Communication between the microprocessor and the Serial Breakout Board on the TS-9150 Diagnostic Test Set is mainly accomplished by U101. U101 is a MAX490 RS-422 interface chip. Since R111 and R112 are installed and L101 and L102 are not installed, the system is configured for transmitting RS-422 data only. This data is sent over the control cable to the Serial Breakout Board, where it is converted to RS-232 levels. After conversion, the data is sent to a PC for display.

4.5.4 A/D Converter

U208 is an LTC1290 12 bit analog to digital converter. It reads the analog voltages from the RF Detector board and converts them to a digital serial stream which can be read by the microprocessor. The output values from the LTC1290 are accurate to within 1.25 millivolts.

4.5.5 Relay Drivers

Several different types of relay drivers are used on the CPU board. The first type is the UCN5801A (U401-403). These drivers supply coil current to the relays on the Input Capacitor board. U401, U402, and U403 are addressed over the parallel data bus of the microprocessor.

The second type of relay driver is a UCN5842A (U501-U504 and U304). These drivers are loaded serially by the microprocessor. U501 through U504 are used to drive the K44P type relays on the coupler chassis. The K44P relays are used to switch the Lseries and Cout network components. U304 lights the status LEDs and sends the READY and FAULT signals back to the radio. U304 also drives the tune/bypass relays on the RF Detector board (1A1A4A1K1 and 1A1A4A1K2), and the soft start relay on the motherboard (1A1A1K101).

The last relay driver type consists of U404, U405, and Q401-Q404. U404 is addressed over the parallel data bus. U405 converts the 5 volt output of U404 to 12 volt logic which drives Q401 through Q404. These transistors provide the coil current for the KC-12 relays on the coupler chassis. The KC-12 relays are used to switch the Lout network components.

4.5.6 Channel Change and Tune Command Detectors

In normal operation, the 80C188EB microprocessor is only active when tuning or changing

channels. The rest of the time, the microprocessor is in “Powerdown Mode”. In Powerdown

Mode, the microprocessor oscillator is stopped. This prevents the oscillator from being heard by the radio receiver.

When the microprocessor is in Powerdown Mode it can only be started up by a RESET signal or a non-maskable interrupt (NMI). Therefore the CPU assembly includes circuitry to detect when the channel information from the radio has changed. When the channel does change, an NMI signal is generated.

The channel change detector consists of U604, U605, and U601. The microprocessor reads the channel lines through U605. Every time a read is performed, the state of each channel line is latched by U604. U605 compares the current channel state from the radio with the state stored in U604. If they are different, a CHANNEL CHANGE signal is sent to U105. U105 generates an

NMI signal to “wake up” the microprocessor when it receives this CHANNEL CHANGE signal

or when a tune command is detected through U104.

4.6 RF Detector Assembly 1A1A4A1

4.6.1 General

The RF 1A1A4A1 Detector contains the phase and magnitude discriminators, -3 dB power pad and precision 50 Ohm calibration termination resistor.

The RF detector provides two variable dc signal voltages to the CPU. The phase signal voltage is proportional to the reactive component of the impedance and the magnitude signal voltage is proportional to the magnitude of the impedance. The phase and magnitude signals are referenced to 50 Ohms.

4.6.2 Magnitude Discriminator

The magnitude discriminator consists of RF transformer T2 and its associated components. It provides a means of measuring the relative magnitude of the transformed antenna impedance relative to 50 Ohms. For a impedance magnitude greater than 50 ohms, the magnitude discriminator produces an output voltage less than the +2.5 VDC reference voltage. For a magnitude less than 50 Ohms, an output greater than the +2.5 VDC reference voltage is produced. A voltage sample is provided from the transmission line by C8 and C9 and is rectified by CR9 producing a DC voltage proportional to the RF voltage on the line. A voltage proportional to the current in the transmission line is generated by transformer T2 and is rectified by CR7. Capacitor C8 is adjusted so that the voltage sample is exactly equal to the current sample when the transmission line is terminated with 50 Ohm non-reactive load. The output of this discriminator is supplied to A/D converter on the CPU assembly.

4.6.3 Phase Discriminator

The phase discriminator consists of transformer T1 and associated components. It provides a means of measuring the relative phase angle at the input to the tuning network by comparing the phase of the line voltage with line current. The phase discriminator output is zero when the transmission line voltage and the current samples are in phase (pure resistance terminating the transmission line). The voltage sample is delivered by C5 R9 and C6 which shifts the phase by 90 degrees. The current sample is generated by transformer T1 and is in phase with the line current. The voltage sample is fed to T1 center tap and the resulting output is detected by CR4 and CR5, producing a DC voltage proportional to the phase difference between the voltage on the transmission line and the current in the line. R8 is the phase discriminator balance control and is adjusted so the phase output is nulled (relative to +2.5 V DC) when the transmission line is terminated with a 50 ohm non-reactive load.

The output of this discriminator is supplied to A/D converter on the CPU assembly.

4.6.4 Attenuator Pad, -3 dB

The 3 dB PI-attenuator pad consists of precision power resistors R1, R2, R3 and R4. The pad is switched between the antenna tuning network and the transmitter whenever the tune relays K1 and K2 are energized. The pad provides protection for the transmitter by limiting the impedance variations placed on the transmitter during the tuning cycle. When a satisfactory tune has been achieved, the pad is switched out. During normal operation (no tune cycle) the pad is not used.

Tune relays K1/ K2 and CR10 (Amber LED) are energized by the tune relay signal from the CPU Assembly.

4.6.5 50 Ohm Calibration Termination

A 50 Ohm, 1% calibration termination resistor controlled by relay K3 allows the phase and magnitude detectors to be calibrated at the beginning of the tune cycle.

When the tune command is received from the transceiver the CPU assembly engages the -3 dB RF power pad and the calibration termination resistor. The phase and magnitude detectors are then evaluated at the tune frequency and their respective error voltages are temporally stored in the CPU memory. The calibration termination is then switched out-of-circuit and the detectors are applied to the tuning network. During the tune cycle the phase and magnitude detector voltage is compared with the 50 Ohm calibration voltage values stored in the CPU memory. The RF tuning network solution is adjusted by the CPU to arrive at the 50 Ohm calibration voltage levels.

This system provides two significant advantages over conventional RF detector systems:

 The phase and magnitude detectors are calibrated for temperature and component

drift each time the coupler is tuned.

 The phase and magnitude detectors do not require periodic field alignment.

4.6.6 TX Only Function

The TX Only function is used under the following conditions:

 Separate transmit and receive antennas.  Two or more transmitters with collocated antennas. Typical of shipboard systems.

The TX Only function opens the RF transmission line between the RF network and the RF input connector J1. This occurs only when the TX ONLY jumper E3 to E4 is installed and the transceiver is in the receive condition or the exciter is in the standby condition. The open transmission line prohibits high voltage generated from the adjacent transmitter from appearing at peripheral equipment such as Pre-postselectors.

During tuning or transmitting the KEYLINE is low (less than 12 V DC). Comparator U1-A buffers the low and turns Q2 off.

During receive the KEYLINE is high (greater than 12 V DC). Comparator U1-A buffers the high, turning Q2 on. Q2 energizes relay K1. The common contact of K1 is connected to the normally open and the common contact of K2 is connected the normally closed contact of K2, thus opening the RF path to the RF IN terminal J1.

4.7 Input Capacitor Assembly 1A1A4A2

4.7.1 General

The Input Capacitor assembly is located on the 50 Ohm side of the RF tuning network.

4.7.2 Configuration and Operation

The Input Capacitor Assembly 1A1A4A2, consists of eleven binary capacitance values from 5.6 pF to 10,233 pF in 5.6 pF steps. Each binary capacitance value is constructed from porcelain high RF power multilayer capacitors. These capacitors are specifically characterized for RF transmitting duty and are ideally suited for antenna matching network application. Each of the individual capacitance values are controlled by a single or dual magnetic latching relay. The latching relays operate by placing a 10 ms pulse on the OPEN or CLOSE field winding. Maximum operating time is 5 ms. Relay drivers and their control is provided by the CPU Assembly.

4.8 Mother Board Assembly 1A1A1

4.8.1 General

The Mother Board 1A1A1 interconnects all assemblies, including the RF network relays, through printed circuit wiring tracks, with exception of the Input Connector Assembly which is connected to the Mother Board by ribbon cable.

4.8.2 DC Power

+28 Volt DC power, supplied by the transceiver or exciter, is filtered by capacitors C1 and C2. A total of 13,600 µF is provided. During power-up the capacitors are charged through a 3 Ohm resistor, R1. When the CPU +5 VDC power is achieved and the microprocessor is operating correctly, the microprocessor energizes K101, bypassing resistor R1.

4.8.3 Series L and Shunt C Relays

The series L, K1-9 and Shunt C, K10-14, relays utilize latching high-speed RF relays that switch the inductive series and capacitive shunt network elements. The relays operate by placing a 7 ms pulse on the OPEN or CLOSE field winding. Maximum operating time is 5 ms.

Each relay is rated for 7 kV and 35 amperes at 2.5 MHz. These ratings, of course decrease as the operating frequency increases, but in all expected network configurations, the relays are conservatively rated.

4.8.4 L-OUT Relays

The L-Out relays, K16, 17 and 18, control the high-value series inductors. These relays and associated network components are used with electrically short antennas such as 23 or 35 foot whip antennas and operating frequencies below 3 MHz. At 1000 Watts, extremely high voltages and high currents can be expected in the L-Out network. This places special operating requirements on these relays. Each relay is rated for 15 kV and 30 amperes at 2.5 MHz. In all expected network configurations, the relays are conservatively rated.

Signal

Description

TUNE COMMAND

This signal is used to initiate a coupler tune. A low is 0V to 2.5V and a high is 7.5V to 12V. A high on this line indicates that the radio system is requesting a tune cycle. The coupler will respond by bringing +28V TUNE ENABLE high (to 28V). The radio system should then bring TUNE COMMAND low and wait for the coupler to bring +28V TUNE ENABLE low. At this point the coupler is ready to receive frequency information over the channel lines. The radio system should then output the frequency in megahertz, in packed BCD format, on the channel lines. Bringing TUNE COMMAND high will cause the coupler to latch the frequency information. When the coupler brings +28V TUNE ENABLE high for the second time, it indicates that the frequency information has been read and that the radio should restore the channel to the channel lines. See Figure 4.9-1 for details of this operation and timing requirements. TUNE COMMAND should be brought low before the application of tune power.

+28V TUNE ENABLE

This is a PNP open collector output. Maximum output drive is 15 mA. Maximum output voltage is the voltage at the +28V supply input. See TUNE COMMAND for details regarding the meaning of this output.

READY

This active low output is pulled low when the coupler is in a tuned state and can accept 1KW RF power. This is an open collector output. At a sink current of 100 mA, the output voltage will be less than 1.1 V. This output is rated for 50 V in the off state. When READY is pulled low, indicating the end of a successful tune, the radio system should stop transmitting tune power. When the coupler detects that tune power has been removed, it will bring +28V TUNE ENABLE low. At this point the coupler is ready to operate at the 1KW power level.

FAULT

This active low output is pulled low when the coupler has failed to find a network solution. This is an open collector output. At a sink current of 100 mA, the output voltage will be less than 1.1 V. This output is rated for 50 V in the off state. When FAULT is pulled low, indicating the end of a failed tune, the radio system should stop transmitting tune power. When the coupler detects that tune power has been removed, it will bring +28V TUNE ENABLE low.

KEYLINE

This signal is presently unsupported by the coupler and should be left unconnected.

The L-Out relays are conventional non-latching relays and must have continuous field current to operate.

Signal

Description

Channel Lines

These 8 channel lines are used to provide the coupler with channel and frequency information. A 10K pull-down resistor is provided which pulls each line to ground. Each line should be pulled to between 3.5V and 5.0V to assert a high. Channels 0 thru 127 are valid for normal operation. These lines are active low, so to select channel 0 (for example) all lines must be pulled to 5V. These lines are also active low when passing frequency information in packed BCD (Binary Coded Decimal) format, so to select 15 MHz (for example), 0xEB must be driven on the channel lines.

COUPLER DETECT

This line allows the radio system to detect the presence or absence of a coupler. This signal is high (about 21 V) when a coupler is present. Current draw from this line should be less than 30mA.

+28V

This is the power supply for the coupler. This supply must be between 22V and 30V. Maximum inrush current is limited to 10A by the 3 ohm resistor R1 on the motherboard. Maximum idle current is 2A. Maximum current draw during a tune cycle is 5A.

RF INPUT

Maximum RF input power when READY is low is 1KW PEP. Tune power should be between 25W and 75W.

Indicator

Meaning

CPU FAULT

This red LED on the 1A1A3 CPU (CR304) indicates that a software error occurred during the CPU program execution which prevents the program from continuing. The CPU will stop program execution at the point where the failure occurred, so the CPU must be reset, or the system power must be cycled, to resume normal coupler operation.

TUNE RELAY

This yellow LED on the 1A1A4A1 RF Detector (CR10) indicates that the magnitude discriminator, phase discriminator, and 3 dB pad are switched into the RF path. This indicator is only lit when the TUNING indicator on the CPU is lit.

5.5 Alignment and Checks

Unless a component of the 1A1A4A1 RF Detector Assembly has failed and required replacement, routine alignment of the CU-9150 is generally not required. This is due to the selfcalibrating nature of the CU-9150. At the beginning of each tune cycle, a 50-ohm calibration load is switched in and the CPU reads the output of the magnitude and phase discriminators. These readings are subtracted from all future measurements, ensuring that minor discriminator imbalances over time, temperature, and frequency do not affect the network solution.

Alignment of the CU-9150 consists solely of adjusting a trimmer capacitor and a potentiometer on the RF Detector Assembly (1A1A4A1). For component and test point locations see Figure

5.5-1. The alignment is accomplished as follows:

1. Turn off the radio set.

2. Remove the 1A1A3 CPU Assembly.

3. Connect the multimeter negative lead to ground on the RF Detector (1A1A4A1TP6).

Connect the positive lead to RF POWER (1A1A4A1TP1).

4. Using alligator clips, ground TP7 and TP8 on the 1A1A4A1 RF Detector to the chassis.

NOTE It may be necessary to remove the 1A1A4 RF Detector/Input Capacitor

Assembly in order to attach a test clip to TP8. Refer to Section 5.2.3 for removal instructions for this assembly. If the assembly is removed, be certain to remove the Phillips head screw which attaches the assembly to the 1A1 Chassis Assembly.

5. Turn the radio set on (it is permissible to power up the coupler without the CPU installed

for alignment and troubleshooting). Set the frequency to 29.0 MHz. Set the mode to

AM. Set the power level to 125W. If a linear amplifier such as a LPA-9600 or an LPA9500 is in the system, turn it off.

Page 56

CU-9150

CAUTION Applying more than tune power (AM carrier power in the 125w power

setting, which is about 40 watts) to the coupler during this alignment procedure will destroy the pad and the calibration load on the RF detector board.

6. Key the radio. The multimeter should read 4.0 to 5.5 volts DC.

7. Unkey the radio. Move the negative lead of the multimeter to the REFERENCE test

point (1A1A4A1TP5) and connect the positive lead to the REFLECTED POWER test point (1A1A4A1TP4). Key the radio. The reading on the multimeter should not exceed

0.5 volts DC.

8. Unkey the radio. Move the positive lead of the multimeter to the PHASE test point

(1A1A4A1TP2). Key the radio. Adjust R8 on the RF Detector so that the reading on the multimeter is between -.02 and .02 volts DC.

9. Unkey the radio. Move the positive lead of the multimeter to the MAGNITUDE test point

(1A1A4A1TP3). Key the radio. Adjust C8 on the RF Detector so the reading on the multimeter is between -.02 and .02 volts DC.

10. Unkey the radio and turn it off. Remove the alligator clips and the multimeter. Put the

CPU back in the chassis.

5.6 Troubleshooting

5.6.1 Coupler Will Not Tune - No Relay Action - No Tuning Fault

1. Check for +28 volts DC at R1 on the 1A1A1 Motherboard Assembly. If the supply is not

present, check for +28 volts at L29 on the 1A1A2 Input Connector assembly. If +28 volts is not present at L29, the problem is probably due to the control cable between the radio set and the CU-9150.

2. Check the voltage drop across R1 on the 1A1A1 Motherboard Assembly. A measured

drop greater than .1 volts indicates that the soft start relay K101 on the 1A1A1 Motherboard Assembly is not being engaged by the 1A1A3 CPU. This is generally the result of the CPU not starting. Proceed to the next step for CPU troubleshooting.

3. Check for a green READY indicator on the 1A1A3 CPU after initial power-up. The lack

of a READY indicator indicates that the CPU is not executing its program correctly. a. Check for +5V at U109 pin 20.

b. Check for +12V at U405 pin 16. c. Check for a 14.7456 MHz signal with an amplitude of at least 4 volts peak to peak on

both sides of Y101.

d. If the three checks above look good, the CPU needs to be analyzed in its test fixture.

Refer to Section 6.1.2.1.

Page 57

CU-9150

5.6.2 Coupler Will Not Tune - No Relay Action - Tuning Fault Indicated

Note the amount of time that elapses between pressing the CPLR TUNE button on the radio and the coupler TUNING FAULT indicator lighting.

If this time is 10 seconds:

1. Using the oscilloscope, check for at least 20 volts peak to peak of RF at the RF INPUT to

the coupler during the tune cycle. If RF is not present at the input to the coupler, a cabling problem probably exists between the radio set and the coupler.

2. If RF is present at the coupler input, check for the same signal at E1 of the 1A1A4A1 RF

Detector Assembly. If the RF signal did not make it this far, the cable between the RF input and the RF Detector Assembly is probably bad.

3. Use the multimeter to check for 4.0 to 5.5 volts between TP1 (RF POWER) and TP6

(GROUND) during the tune cycle. The CPU waits for this signal to go high before

starting to look for a tune solution. If this time is two seconds: The software revision in the transceiver or exciter does not support the CU-9150. Contact Sunair

Product Support for software upgrade information.

5.6.3 Relays Operate But Tuning Fault Indicated

Run a BITE test. Refer to Section 6.1.2.4 for instructions and theory. If the BITE test fails, a TS-9150 Diagnostic Test Set is required to display which components the coupler suspects to be faulty.

If the BITE test is successful, the radio system is probably at a frequency where the coupler cannot find an acceptable network solution. This situation can usually be alleviated by changing the frequency. If changing frequency is not possible and a long-wire antenna is being used, lengthening or shortening the antenna somewhat will often result in successful tunes.

5.6.4 Coupler Tunes but Memory Does Not Work

This situation is usually results when the coupler CPU does not receive the channel information from the radio correctly.

1. Check that the control cable is correctly wired.

2. Turn the radio set off. Using the multimeter, check each of the inductors on the 1A1A2

Input Connector Assembly for continuity.

3. Check L601 through L608 on the 1A1A3 CPU Assembly for continuity.

4. If the above checks fail to find the problem, replace the 1A1A3 CPU Assembly.

5.7 DIP Switch Settings

All of the 1A1A3S201 CPU DIP switches should normally be in the down position. Table 5.7-1 explains the function of the switch settings.

Page 58

CU-9150

Switch

Function

Setting this switch to the UP position enables the keyline detector circuitry. This function is currently unsupported by the CPU software, so this switch should always be set to the DOWN position.

Setting this switch to the UP position stops the CPU from going into powerdown mode after tuning or changing channels. This switch should be in the up position when using the Display Board in the TS-9150 Diagnostic Test Set, but should be set to the DOWN position for normal operation.

Setting this switch to the UP position causes the coupler to allow more time for the relays to change state. As the relays age, they take longer to change state. Try setting this switch to the UP position on couplers which start to indicate tune failures intermittently and which have been in service for several years. The tune timeout changes from 10 seconds to 17 seconds when this switch is set.

Not used.

After making a change to the DIP switch settings, a CPU reset is required to make the change effective. This can be done by pressing S101 on the CPU board or by powering the system down and then up again.

6.1.2 Test Set Operation

6.1.2.1 CPU Test Fixture Operation

In order to perform a board level test of the 8120030095 Coupler CPU assembly, the components listed in Table 6.1-3 are required. All of the items that have Sunair part numbers are included with the 8120907591 Diagnostic Test Set.

Table 6.1-3. Board Level Test Components Required

To perform a board level test:

1. Remove the EPROM from the U301 position of the board under test.

2. Install the Test EPROM PN 8120034091 in the U301 position.

3. Remove PAL W/CU-9150-H software from U105 position.

4. Install PN 8120033698 PAL W/CU-9150 software in U105 position.

6-2 Use or disclosure of information from this document is subject to the restrictions

indicated on the proprietary/confidentiality page of this document.

Page 87

CU-9150

5. Set S1 on the test fixture to its OFF (down) position.

6. Set all of the switches on S201 of the board under test to the OFF (down) position.

7. Set S601 on the test fixture to RUN EEPROM TEST.

Configure the PC or terminal serial communications parameters for 8 bits, no parity, one stop bit, at 9600 bps. Choose ASCII if more than one character set is supported by the terminal or program. No special escape codes are utilized by the test software, so most terminal emulation modes will work fine. VT-100 terminal emulation works well and is supported by most PC terminal programs.

If Hyperterminal is being used in a Windows 95 environment, the communications setup can be accomplished as follows:

1. Open the Hyperterminal folder by clicking Start in the lower left hand corner, clicking

Accessories, and Hyperterminal.

2. Start Hyperterminal by clicking on the Hypertrm.exe icon.

3. Choose a name for the new “connection” being created. The “connection” is really just a

collection of serial communications parameters which can be stored for later use.

4. Choose an icon for the connection and click OK.

5. On the next dialog box, select the desired COM port under the “Connect using”. Most users will

need to select either Direct to Com 1 or Direct to Com 2. Click OK. The next dialog box is where the actual communication parameter setup takes place.

6. Set the Bits per second list box to 9600.

7. Set the Data bits list box to 8.

8. Set the Parity list box to None.

9. Set the Stop bits list box to 1.

10. Set the Flow control list box to None.

11. Click OK.

The Hyperterminal main screen now appears, and is ready to display the test fixture output. When the test session is complete and Hyperterminal is closed, it will ask if the session should be saved. Answer

Yes to this question so that Hyperterminal will save the connection, and create a new icon in the

Hyperterminal folder. In the future, Hyperterminal should be started by clicking on this new icon so that the communications parameters do not have to be set up for every test session.

1. Connect P1 (TO PC) on the test fixture to the PC or terminal serial port. Plug the CPU to be

tested into the fixture. Note that the component side the board should be facing the front of the fixture. The front of the fixture is labeled FRONT OF BOARD. This is important, as it is possible to plug the CPU into the fixture backwards.

CAUTION Carefully observe the orientation of the board under test with respect to the test

fixture. Make sure that the component side of the board under test faces toward the front of the test fixture (labeled FRONT OF BOARD). Failure to do so can result in damage to the fixture and the board under test.

CU-9150

2. Connect P2 (TO BOARD UNDER TEST) to J1 of the CPU assembly being tested using cable

PN 8120907892.

3. Set the power supply output voltage to 28V. Turn the power supply off and connect it to J3 on

the test fixture.

4. Turn on the power supply.

5. Turn on the fixture power supply using S1.

6. Follow the instructions that appear on the terminal screen.

If the board under test is good, the last line displayed on the terminal at the completion of the test will be

PASSED. Otherwise FAILED will be displayed.

When a test fails, a message describing the failure will be displayed on the terminal and the program will not continue until the CONTINUE button is pressed on the test fixture.

To restart the test, press the reset switch (S101) on the board under test. Since the EEPROM test takes quite a while to complete, it can be bypassed during troubleshooting by

setting S602 on the test fixture to BYPASS EEPROM TEST and pressing the reset switch (S101 on the board under test). In this case, the program will always display *** TEST FAILED *** at the end of the test.

At the end of the test, all four LEDs at the top of the board under test should be lighting in sequence. Before installing the CPU board back in a coupler, remove the test EPROM and put the standard

EPROM PN 8120033299 back into the U301 position. Remove PN 8120033698 from U105 position and reinstall PN 8120810198 into position U105.

6.1.2.2 Display Board Operation

The display board allows the user to view and modify the state of the relays in the coupler. The display board is little more than a collection of displays and switches that can be addressed serially by the coupler CPU. The display board occupies the right side of the Diagnostic Test Set case.

In order for the display board to be utilized, DIP switch number 7 of S201 on the coupler CPU must be in the UP (ON) position. However, with the switch in this position, the CPU clock is active at all times, and is easily heard by the radio receiver. For this reason, DIP switch number 7 of S201 should only be in the UP position during coupler diagnostics, and should be in the DOWN position during normal operation.

Turn the radio set off. Remove the coupler cover. Remove the inner cover. Set DIP switch number 7 of S201 on the coupler CPU to its UP position. Connect cable PN 8120907892 (DB9 Male to Male) between J1 of the CPU board (labeled DISPLAY on the inner cover) and J1 on the display board (labeled

TO COUPLER CPU). Set the ON/OFF switch on the display board to ON. Turn the radio set on.

The display board now indicates the state of each relay in the coupler. It also shows the sum total capacitance or inductance values for each of the network elements.

6-4 Use or disclosure of information from this document is subject to the restrictions

indicated on the proprietary/confidentiality page of this document.

Page 89

CU-9150

At this point, the value of any network element can be modified by pressing the up or down buttons for that element. For instance, pressing C IN UP will add one increment of capacitance (about 5 pF) to the amount of Cin that is already active. Pressing the C IN UP button and holding it down will cause capacitance to be added to Cin continuously. The buttons for Lseries, Cout, and Lout work in a similar manner.

The red LEDs for each network component correspond to a relay. When a LED is lit, it indicates that the component associated with that relay is in use in the network. If the component is a capacitor, then the relay is closed. If the component is an inductor, then the relay is open unless it is the Lout bypass relay. The Lout bypass relays (K15 and K19 on the chassis) are in the bypass state (connected to the Normally Closed contact) when the LOUT BYPASS LED is illuminated.

The HOME button causes the coupler to go to a state in which all network elements are 0 pf or 0 µH. The TUNE/KW button causes the coupler to switch the state of the RF detector. When the red TUNE

LED is lit, the detector is switched into the RF path and the readings from the magnitude and phase detectors are displayed on the display board.

CAUTION Never apply more than tune power to the coupler when the red

TUNE LED is lit on the display board. Tune power is AM carrier

power and is roughly 40 watts. Higher power levels will destroy the RF detector components.

A network solution can be arrived at by hand when the red TUNE LED is lit, and AM carrier power is applied by keying the radio in AM mode (with the LPA-9600 kilowatt amplifier turned off). When the magnitude and phase displays are as close to zero as possible, then the coupler is tuned.

The magnitude and phase displays show the magnitude and phase detector output values in millivolts. When the green KW LED is lit, the RF detector is switched out of the RF path. The magnitude and

phase detectors are no longer active, so the display board simply indicates “-----” on the magnitude and phase displays. It is safe to transmit at the 1000 watt power level in this state.

The SAVE and RECALL keys work in conjunction with the CHANNEL indicator on the display board. Note that the channel indicator does not indicate the channel the radio is on. The channel indicator provides access to the coupler channel memory. To save a network solution for later use, dial in a channel number using the knobs below the channel indicator and press the SAVE button. This will save the network in that channel location in the coupler’s memory. The network solution can be recalled at a later time in two ways. The first method is to set the radio to the desired channel number. The other method is to use the knobs below the channel indicator to dial in the desired channel, and then press the

RECALL button.

The CPU TUNE START and CPU TUNE STEP keys are reserved for future use and are disabled.

6.1.2.3 Serial Breakout Board Operation

The Serial Breakout Board provides the user with the ability to see the steps the coupler took in arriving at a network solution. The Serial Breakout Board is installed on the left side of the Diagnostic Test Set case.

Table 6.1-4 lists the equipment to use the Serial Breakout section of the test set.

This list assumes that there is an existing cable between the LPA-9600/LPA-9500 and the antenna coupler.

The TuneView software can be run directly from the distribution floppy, but it is preferable to have it resident on the hard drive. To install TuneView:

1. Insert the TuneView diskette into the floppy drive

2. Open a DOS window

3. Create a new directory ( md\TuneView )

4. Change to that directory ( cd\TuneView )

5. Copy the TuneView executable ( copy a:TuneView.exe . )

6. Close the DOS window ( exit )

7. Create a shortcut to the TuneView executable on the desktop.

Disconnect the control cable between the linear amplifier and the coupler at the amplifier end (J4 on the amplifier rear panel). Connect this cable to J2 on the Diagnostic Test Set (labeled TO KILOWATT

COUPLER). Connect the other control cable (PN 8092500096) between J1 of the Diagnostic Test Set

and J4 of the amplifier. Using the DB25 to DB9 cable PN 1012900037, connect the 25-pin end to J5 of the Diagnostic Test Set Serial Breakout Board. Connect the other end to the serial port of the PC running TuneView.

Start TuneView. The first time TuneView is run, it must be configured to use the COM port connected to the Serial Breakout Board. On the menu, click on Settings, and then on Com Port. This will bring up a dialog box that allows selection of the desired COM port. This information is stored on disk so that the correct COM port is selected the next time TuneView is run.

The TuneView main screen displays several parameters describing the most recent tune. These are listed in Table 6.1-5.

The magnitude and phase values for each network are plotted on the chart as a small red square. The center of the chart is magnitude=0 mV, phase=0 mV. This corresponds to a network input impedance of 50 ohms at 0 degrees. Positive phase values are plotted in the top half of the chart. Negative magnitude values are plotted on the right hand side of the chart. This is because the magnitude detector output is negative for impedances which have a magnitude greater than 50 ohms, and positive for impedances

Term

Definition

Channel

The radio channel that was tuned.

Freq

The radio frequency that was tuned. This frequency is truncated to display megahertz only. For example, if the radio frequency was 6.99999 MHz, TuneView would show 6 under Freq.

Magoffset

The output of the magnitude detector in millivolts when the 50 ohm calibration load is switched in. This number is subtracted from all future readings of the detector, so minor detector imbalances over time, temperature, and frequency do not affect the network solution. If this number is greater than 250 or less than

-250, the RF detector board should be adjusted to null the magnitude detector.

Phaseoffset

The output of the phase detector in millivolts when the 50 ohm calibration load is switched in. This number is subtracted from all future readings of the detector, so minor detector imbalances over time, temperature, and frequency do not affect the network solution. If this number is greater than 250 or less than -250, the RF detector board should be adjusted to null the phase detector.

Network #

This is the number of the attempt by the coupler to arrive at a network solution. Each network consists of a value of Cin, Lseries, Cout, and Lout. The magnitude and phase readings corresponding to this network are also displayed. The larger the network number, the later in the tune cycle that it occurred.

Cin

The input capacitance of the currently selected network. Each bit in the top number corresponds to a relay. If the bit is 1, then the corresponding relay is closed, making its associated Cin component active in the network. The bottom number is Cin in picofarads.

Lseries

The series inductance of the currently selected network. Each bit in the top number corresponds to a relay. If the bit is 1, then the corresponding relay is open, making its associated Lseries component active in the network. The bottom number is Lseries in microhenrys.

Cout

The output capacitance of the currently selected network. Each bit in the top number corresponds to a relay. If the bit is 1, then the corresponding relay is closed, making its associated Cout component active in the network. The bottom number is Cout in picofarads.

Lout

The output inductance of the currently selected network. If the bit is 1, then the corresponding relay is open, making its associated Lout component active in the network. The bottom number is Lout in microhenrys. If lout=0, then the Lout bypass relays (K15 and K19 on the chassis) are in the bypass state (connected to the Normally Closed contact).

which have a magnitude less than 50 ohms. Using this convention, the plot produced is similar to a Smith chart.

Table 6.1-5. TuneView Parameters

The arrow keys control which network is displayed. The currently selected network is shown on the chart as the single blue square. All of the other attempts are shown as red squares. Pressing the UP

ARROW key moves to networks earlier in the tune cycle. Pressing the DOWN ARROW key moves to

networks later in the tune cycle. The PAGE UP key performs the same function as the UP ARROW key. The PAGE DOWN key

performs the same function as the DOWN ARROW key. The box at the bottom of the screen shows a log of the tuning attempts for the current session. For each

tune attempt, a line is added showing the channel number and whether or not the tune was successful. The currently displayed tune history can be saved to a file using the menu item File, and then Save As.

This file can later be loaded by clicking File, then Open, and selecting the desired file.

6.1.2.4 BITE

The built in test function (BITE) of the coupler is initiated under the BITE menu on the radio, by the

CU-BITE softkey. Pressing CU-BITE causes the radio to tune the coupler on four dedicated BITE

channels, shown below:

Channel Frequency 250 1.75 MHz

251 5.75 MHz 252 16.75 MHz 253 29.75 MHz

The coupler is aware that a BITE test should be performed because these channels are only used for BITE.

After a tune solution is found, but before sending a READY signal back to the radio, the coupler checks a portion of the relays. This check consists of changing the state of each relay, one at a time, and determining if this change makes a sufficient difference in the readings of the magnitude and phase detectors.

If the coupler does not detect a large enough change in the magnitude and phase detector readings as it changes the state of each relay, it reports a tuning FAULT signal back to the radio. If the coupler does detect a large enough change in the magnitude and phase detector readings, it reports a READY signal back to the radio.

When a CU-BITE failure occurs, it is necessary to use TuneView and the Serial Breakout Board to find out which components the coupler determined to be faulty. Connect the Serial Breakout Board and start TuneView as detailed in Section 6.1.2.3. Run the CU-BITE test again. The list box at the bottom of the TuneView screen will indicate which components need attention.

The list box also contains information about each relay check. The state of all of the relays in shown along with the magnitude and phase difference that was generated by toggling the state of one relay.

The small value components are not checked individually. Rather, the three smallest Cin values (C1, C2, and C3 on the Input Capacitor board) are checked as a group and the three smallest Lseries values (L9, L1, and L2 on the chassis) are checked as a group. The coupler switches the three smallest Cin components out of the network and takes a magnitude and phase reading. It then switches the three smallest components into the network and takes another magnitude and phase reading. As long as these two readings have a large enough difference between them, all of the components in the group are assumed to be working properly. The three smallest Lseries values are checked in the same way.
