Chapter 1 Introduction

1.1 General

This manual includes all the information needed to maintain peak product performance and maximum working time for the ASTRO XTS 5000 radio. This detailed level of service (component level) is typical of the service performed by some service centers, self-maintained customers, and distributors.

Use this manual in conjunction with the ASTRO XTS 5000 VHF/UHF Range 1/700–800 MHz Digital Portable Radios Basic Service Manual (Motorola part number 6881094C28), which can help in troubleshooting a problem to a particular printed circuit (PC) board.

Conduct the basic performance checks outlined in the basic service manual first to verify the need to analyze the radio and to help pinpoint the functional problem area. In addition, you will become familiar with the radio test mode of operation, which is a helpful tool. If any basic receive or transmit parameters fail to be met, the radio should be aligned according to the radio alignment procedure.

Included in other areas of this manual are functional block diagrams, detailed theory of operation, troubleshooting charts and waveforms, schematics, and parts lists. You should become familiar with these sections to aid in determining circuit problems. Also included are component location diagrams to aid in locating individual circuit components and some IC diagrams, which identify some convenient probe points.

“Chapter 3, Theory of Operation,” on page 3-1, contains detailed descriptions of the operations of

many circuits. Once you locate the problem area, review the troubleshooting flowchart for that circuit to fix the problem.

Chapter 2 Radio Power

This chapter provides a detailed circuit description of the power distribution of an ASTRO XTS 5000 radio.

2.1 General

In the ASTRO XTS 5000 radio, power (B+) is distributed to two boards: the transceiver (RF) board and the VOCON board (see Figure 2-1 on page 2-2 for UHF Range 1 (R1) and 700–800 MHz, and

Figure 2-2 on page 2-2 for VHF). In the case of a secure model radio, B+ is also supplied to the

encryption module . Power for the radio is provided through a battery supplying a nominal 7.5 Vdc directly to the

transceiver. The following battery types and capacities are available:

B+ from the battery is electrically switched to most of the radio, rather than routed through the On/ Off/volume control knob, S1. The electrical switching of B+ supports a keep-alive mode. Under software control, even when the On/Off/volume control knob has been turned to the Off position, power remains on until the MCU completes its power-down, at which time the radio is physically powered down.

2.2 DC Power Routing—Transceiv er Board

NOTE: Refer to Table 8-1, “List of Transceiver Schematics and Board Overlays,” on page 8-1 for a

listing of schematics showing the transceiver board DC power routing components.

Connector J1, the B-plus assembly, connects the battery to the transceiver board. Capacitors C1, C2, and C3 provide protection against momentary breaks at the B-plus connector due to contact bounce when the radio is dropped.

UHF R1 and 700–800 MHz: Components C5, E4, C7, and E1 form a power-line filter for signal RAWB+, which supplies battery voltage to the transmitter PA.

VHF: Component E1 forms a power-line filter for signal RAWB+, which supplies battery voltage to the transmitter PA.

Transistor Q1, controlled by signal SWB+ (SB+ for VHF) from the VOCON board, turns on XB+, which supplies to the 5-V linear regulator and TX_ALC block.

Fuse F901 and filter C1 1, L1, C10 (C14, L1, C13 for VHF) supply fused B-plus to the VOCON board. In turn, the VOCON board supplies VSW1, regulated 3.8 Vdc, from the Global Control Audio and Power (GCAP) switching regulator to the XCVR. Switch Q99 (Q503 for VHF), controlled by SWB+, turns on V38 to the XCVR 3-V linear regulators. The XCVR regulated power supplies are summarized in Table 2-3.

2.3 DC Power Routing—VOCON Board

NOTE: Refer to T able 8-2, “List of VOCON Schematics and Board Overlays,” on page 8-1 for a listing

of schematics showing the VOCON board DC power routing components.

Raw B+, or unswitched B+, (UNSW_B+) is routed to connector P1 on the transceiver board, and then on to P201 on the VOCON board. Here the UNSW B+ is forwarded to the radio’s control top On/Off/volume knob through connector J101 and a flex circuit, as well as to regulator U505 (VCC5).

The On/Off/volume knob controls B+SENSE to Q502, which in turn controls Q501. Transistor Q501 is a solid-state power switch that provides SW B+ to the VOCON board, the audio P A, the GCAP II IC (via GCAP_B+), and back to the transceiver board.

In the case of a secure radio model, SW B+ and UNSW B+ are also supplied to the encryption module through connector J701.

6881094C31-C October 14, 2003

2-4 Radio Power: DC Power Routing—VOCON Board

Transistor Q501 is also under the control of the microcontroller unit (MCU) via Vref from U501. This allows the MCU to follow an orderly power-down sequence when it senses that B+SENSE is off. This sense is provided through MECH_SW_BAR (inverted B+SENSE, see Q508).

The digital circuits in the VOCON board are powered from regulators located in the GCAP II IC (U501), an external 5 Vdc regulator (VCC5, U505), and an external 1.55 Vdc regulator (VSW_1.55V, on NNTN4717 VOCON kit only). The GCAP II IC provides three supplies: VSW1, VSW2, and V2. These regulators are software programmable. T able 2-4 lists the supply voltages and the circuits that use these voltages.

4.1 Handling Precautions

Complementary metal-oxide semiconductor (CMOS) devices, and other high-technology devices, are used in this family of radios. While the attributes of these devices are many, their characteristics make them susceptible to damage by electrostatic discharge (ESD) or high-voltage charges. Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special precautions must be taken to prevent device damage during disassembly, troubleshooting, and repair. Handling precautions are mandatory for this radio, and are especially important in lowhumidity conditions. DO NOT attempt to disassemble the radio without observing the following handling precautions.

disassemble the radio or troubleshoot a board without first referring to the following Handling Precautions section.

1. Eliminate static generators (plastics, Styrofoam, etc.) in the work area.

2. Remove nylon or double-knit polyester jackets, roll up long sleeves, and remove or tie back loose-hanging neckties.

3. Store and transport all static-sensitive devices in ESD-protective containers.

4. Disconnect all power from the unit before ESD-sensitive components are removed or inserted unless otherwise noted.

5. Use a static-safeguarded workstation, which can be accomplished through the use of an antistatic kit (Motorola part number 01-80386A82). This kit includes a wrist strap, two ground cords, a static-control table mat and a static-control floor mat.

4.3 Voltage Measurement and Signal Tracing

It is always a good idea to check the battery voltage under load. This can be done by checking the OPT_B+_VPP pin at the side connector (pin 4). The battery voltage should remain at or above

7.0 Vdc. If the battery voltage is less than 7.0 Vdc, then it should be recharged or replaced as necessary prior to analyzing the radio.

In most instances, the problem circuit may be identified using a multimeter, an RF millivoltmeter, oscilloscope (preferably with 100 MHz bandwidth or more), and a spectrum analyzer.

When checking a transistor or module, either in or out of

C a u t i o n

circuit, do not use an ohmmeter having more than 1.5 Vdc appearing across test leads or use an ohms scale of less than x100.

Troubleshooting Procedures: Power-Up Self-Check Errors 4-5

4.5 Power-Up Self-Check Errors

Each time the radio is turned on, the MCU and DSP perform a series of internal diagnostics. These diagnostics consist of checking such programmable devices as the FLASH ROMs, the EEPROM, and SRAM devices.

Problems detected during the power-up self-check routines are presented as error codes on the radio’s display. For non-display radios, the problem is presented at power up by a single, lowfrequency tone. Table 4-3 lists possible error codes, a description of each error code, and a recommended correc tive action.

Chapter 5 Troubleshooting Charts

This section contains detailed troubleshooting flowcharts. These charts should be used as a guide in determining the problem areas. They are not a substitute for knowledge of circuit operation and astute troubleshooting techniques. It is advisable to refer to the related detailed circuit descriptions in the theory of operation sections prior to troubleshooting a radio.

5.1 List of Troubleshooting Charts

Most troubleshooting charts (see Table 5-1) end up by pointing to an IC to replace. It is not always noted, but it is good practice to verify supplies and grounds to the affected IC and to trace continuity to the malfunctioning signal and related circuitry before replacing any IC. For

instance, if a clock signal is not available at a destination, continuity from the source IC should be checked before replacing the source IC.

5.4 DC Supply Failure—Page 1

NOTE: Since the failure of a critical voltage supply might cause the radio to automatically power

down, supply voltages should first be probed with a multimeter. If all the board voltages are absent, then the voltage test point should be retested using a rising-edge-triggered oscilloscope. If the voltage is still absent, then another voltage should be tested using the oscilloscope. If that voltage is present, then the original voltage supply in question is defective and requires investigation of associated circuitry.

Synopsis

This failure relates only to secure-equipped radios and indicates a power-up self-test failure for the secure module. More specifically this failure indicates a failure in communications between the DSP and secure module. The secure module is not considered field repairable so troubleshooting is limited to verifying a problem with the module and replacing. Typical failure modes would be:

1) Open between secure module and VOCON board at J701.

2) Failure of the SSI bus that the DSP uses to communicate with the secure module.

3) Failure to get proper supplies and grounds to J701.
