  • Page 37: Basic Theory Of Operation

    Basic Theory of Operation General The ASTRO Digital XTS 3000 radio is a wideband, synthesized, fixed-tuned radio available in the 800MHz band. All ASTRO Digital XTS 3000 radios are Overview capable of both analog operation and ASTRO mode (digital) operation in 12.5kHz or 25kHz bandwidths.

  • Page 38: Astro Mode Of Operation

    When the radio is transmitting, microphone audio is passed from the audio power amplifier (PA) to the DSP-support IC, where the signal is digitized. The DSP-support IC passes digital data to the DSP, where pre-emphasis and low- pass (splatter) filtering are done. The DSP returns this signal to the DSP- support IC, where it is reconverted into an analog signal and scaled for application to the voltage-controlled oscillator as a modulation signal.

  • Page 39: Controller Board Basic Theory Of Operation

    The digital back-end IC consists of an amplifier, the second mixer, an IF analog-to-digital converter, a baseband down-converter, and a 2.4MHz synthesis circuit to provide a clock to the DSP-support IC on the vocoder board. The second LO is generated by discrete components external to the IC.
  • Page 40 also required for functionality. It is programmed using parallel programming from the microcontrol unit and the DSP-support IC. The DSP-support IC performs analog-to-digital and digital-to-analog conversions on audio signals. It contains attenuators for volume, squelch, deviation, and compensation, and it executes receiver filtering and discrimination.

  • Page 41: Radio-Level Troubleshooting

    If the radio needs further troubleshooting, it must be sent to the depot. Board- and component-level and service information can be found in the “ASTRO Digital XTS 3000 Portable Radios Detailed Service Manual,” Motorola publication number 68P81083C90. Power-Up When the radio is turned on (power-up), the radio performs cursory tests to determine if its basic electronics and software are in working order.

  • Page 42: Operational Error Codes

    Operational Error During radio operation, the radio performs dynamic tests to determine if the radio is working properly. Problems detected during these tests Codes 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.
