This detailed theory of operation can help isolate the problem to a particular component. This manual is to be used in conjunction with the ASTRO XTS 2500, XTS 2500 , XTS 2250, XTS 1500, MT 1500 Digital Portable Radios Basic Service Manual (Motorola part number 6816984H01), which uses the pass/fail service approach to radio problems.
Page 68: Antenna Switch
4.1-2 VHF Detailed Theories of Operation: Antenna Switch The 13V, being generated by the positive voltage multiplier circuitry, should be present at pin A2 of U202. The serial interface (SRL) is connected to the microprocessor via the data line (pin F1 of U202), the clock line (pin F4 of U202), and the chip-enable line (pin G1 of U202).
Page 69: Front End
VHF Detailed Theories of Operation: Receiver 4.1-3 4.1.4.1 Front End For the purposes of this discussion, the receiver front end is defined as being the circuitry from the antenna switch to the output of the IF crystal filter. The VHF front end converts the received RF signal to the 1st IF frequency of 44.85 MHz, while at the same time providing for spurious immunity and adjacent channel selectivity.
Page 70: Transmitter
4.1-4 VHF Detailed Theories of Operation: Transmitter The ABACUS IC (U401) is electronically programmable. The amount of filtering, which is dependent on the radio channel spacing and signal type, is controlled by the microcomputer. Additional filtering, which used to be provided externally by a conventional ceramic filter, is replaced by internal digital filters in the ABACUS IC.
Page 71: Vocon Functional Blocks
VHF Detailed Theories of Operation: VOCON Functional Blocks 4.1-5 U103 senses the temperature of the printed circuit board (PCB) near the RF Power Amplifier (Q101) and provides a dc level representative of this temperature to pin 30 of the PCIC. The PCIC uses this input to cut back the output power level after a certain temperature threshold is reached.

Page 159: Chapter 5 Troubleshooting Procedures
Chapter 5 Troubleshooting Procedures Introduction The purpose of this chapter is to aid in troubleshooting problems with the ASTRO XTS 2500/ XTS 2500 digital portable radio. It is intended to have enough detail to localize the malfunctioning circuit and isolate the defective component.
Page 160: Standard Bias Table
Troubleshooting Procedures: Standard Bias Table In most situations, the problem circuit may be identified using a multimeter, 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 circuit, do not use an ohmmeter having more than 1.5 volts dc appearing across the test leads, or use an ohms scale of less than x100.
Page 161: Power-Up Self-Check Errors
Troubleshooting Procedures: Power-Up Self-Check Errors Power-Up Self-Check Errors Each time the radio is turned on, the microcontroller unit (MCU) and the digital signal processor (DSP) perform some internal diagnostics. These diagnostics consist of checking the programmable devices such as the FLASH ROMs, internal and external EEPROMs, and SRAM devices. At the end of the power-up self-check routines, if an error exists, the appropriate error codes may be read using the Customer Programming Software (CPS) from the RS232/USB bus on the universal (side) connector.
Page 162: Operational Error Codes
Troubleshooting Procedures: Operational Error Codes Operational Error Codes During radio operation, the radio performs dynamic tests to determine if the radio is working properly. Problems detected during these tests are presented as error codes on the radio’s display. The presence of an error code should prompt a user that a problem exists and that a service technician should be contacted.
Page 163 Troubleshooting Procedures: Operational Error Codes Table 5-4. Additional Error Code Action Items (Continued) Error Code Corrective Action 02/88 Cycle power to the radio. If this does not fix the problem, then the radio should be sent to the depot for re-flashing of the DSP code. Continued failure requires examination and/or replacement of the SRAM (U804).
