Page 32: Radio Description
® FLASHport The ASTRO APX 2000/ APX 4000/ APX 4000Li radio utilizes Motorola’s FLASHport technology. FLASHport makes it possible to add software that drives the radio’s capabilities both at the time of purchase and later on. Previously, changing a radio’s features and capabilities meant significant modifications or buying a new radio.
Page 33: Chapter 2 Basic Maintenance
Chapter 2 Basic Maintenance This chapter describes the preventive maintenance and handling precautions. Each of these topics provides information vital to the successful operation and maintenance of the radio. General Maintenance In order to avoid operating outside the limits set by the FCC, align the ASTRO APX 2000/ APX 4000/ APX 4000Li radio’s reference oscillator every time the radio is taken apart, or once per year, whichever comes first.
Page 34 Basic Maintenance: Safe Handling of CMOS and LDMOS Devices • The APX 2000/ APX 4000/ APX 4000Li radio has a vent port that allows for pressure equalization in the radio. Never poke this vent with any objects, such as needles, tweezers, or screwdrivers. This could create a a u t i o n leak path into the radio and the radio’s submergibility will be lost.
Page 35: Chapter 3 Basic Theory Of Operation

Page 40: Figure 3-7. Transmitter (Vhf) Block Diagram
Basic Theory of Operation: Analog Mode of Operation 3.2.2 Transmitting When the radio is transmitting, microphone audio is digitized and then processed by the DSP and sent to the Trident IC (see Figure 3-7, Figure 3-8, Figure 3-9 Figure 3-10) via the SSI interface. The Trident IC processes the SSI data for application to the voltage controlled oscillator as a modulation signal.

Page 42 Basic Theory of Operation: Analog Mode of Operation 3.2.2.2 UHF1/UHF2 Transmit Once a UHF frequency for transmit has been selected, the Trident IC and the accompanying logic circuitry will enable the voltage controlled oscillator which then generates the desired transmit frequency.
Page 43: Digital (Astro) Mode Of Operation
Basic Theory of Operation: Digital (ASTRO) Mode of Operation Digital (ASTRO) Mode of Operation In the ASTRO (digital) mode of operation, the transmitted or received signal is limited to a discrete set of frequency deviation levels. The receiver handles an ASTRO-mode signal identically to an analog-mode signal, up to the point where the DSP decodes the received data.
Page 44 3-10 Basic Theory of Operation: Controller Section The ARM controller core of the OMAP processor handles the power up sequence of all devices, including firmware upgrades, and all operating system tasks that are associated with FLASH and SDRAM memories and user interface communication. The FLASH memory (64 MB) is required to store the firmware, tuning, and Codeplug settings, which upon initialization get read and stored into SDRAM (32MB) for execution.

Introduction: Radio Description Radio Description The ASTRO APX 1000 radio provides improved voice quality across more coverage area. The digital process, called embedded signaling, intermixes system signaling information with digital voice, resulting in improved system reliability and the capability of supporting a multitude of advanced features.
Page 163: Chapter 2 Basic Maintenance
General Maintenance In order to avoid operating outside the limits set by the FCC, align the ASTRO APX 1000 radio’s reference oscillator every time the radio is taken apart, or once per year, whichever comes first. (See Section 6.5.1).
Page 164 Basic Maintenance: Safe Handling of CMOS and LDMOS Devices • The APX 1000 radio has a vent port that allows for pressure equalization in the radio. Never poke this vent with any objects, such as needles, tweezers, or screwdrivers. This could create a leak path into the radio and a u t i o n the radio’s splash protection reliability will be lost.

ASTRO mode (digital) operation (12.5 kHz only), X2-TDMA mode (25 kHz only) and Phase 2 TDMA mode (12.5 kHz only). NOTE: The APX 1000 M1.5, M2 and M3 radio support Global Positioning System (GPS) but do not support Bluetooth, MACE and Accelerometer functions. As such, disregard all references to the functions mentioned above in “Chapter 3 Basic Theory of...
Page 166: Major Assemblies
Basic Theory of Operation: Major Assemblies Major Assemblies The ASTRO APX 1000 radio includes the following major assemblies (See Figure 3-1.): • Main Board – Contains all transmit, receive, and frequency generation circuitry, including the digital receiver back-end IC and the reference oscillator. The main board also contains a dual...
Page 167 Basic Theory of Operation: Analog Mode of Operation Analog Mode of Operation This section provides an overview of the analog mode receive and transmit theory of operation. 3.2.1 Receiving The RF signal is received at the antenna and is routed through the Harmonic Filter, followed by the Antenna Switch and finally the 15dB Step Attenuator IC.

ΣΔ ADC Filter Rx LO DIG_CTRL_ATTH 18Mhz Abacus III To GPS Diplexer Figure 3-4. Receiver Block Diagram (700/800 MHz) 3.2.1.1 GPS The GPS signal is tapped at the antenna port via a series resonant network (diplexer) which provides a very low capacitive load to the transceiver.
Page 169 Basic Theory of Operation: Analog Mode of Operation 3.2.1.4 700/800 MHz Front-End From the 15 dB Step Attenuator, a 700/800 MHz band signal is routed to the first band SPST switch which selects the 700 or the 800 band signal and routes it to the appropriate first pre-selector filter. A second band select switch selects the output of the appropriate filter and applies it to an LNA followed by a similar pre-selector filter/ band-select switch circuit.
Page 170 Basic Theory of Operation: Analog Mode of Operation 3.2.2.1 VHF Once a VHF frequency for transmit has been selected, the Trident IC and the accompanying logic circuitry will enable the voltage controlled oscillator which then generates the desired transmit frequency. This transmit signal is then routed to the TX buffer amplifier which amplifies the signal. The signal is routed to the VHF Driver amplifier and then to the discrete final power amplifier.
Page 171: Digital (Astro) Mode Of Operation
Basic Theory of Operation: Digital (ASTRO) Mode of Operation Digital (ASTRO) Mode of Operation In the ASTRO (digital) mode of operation, the transmitted or received signal is limited to a discrete set of frequency deviation levels. The receiver handles an ASTRO-mode signal identically to an analog-mode signal, up to the point where the DSP decodes the received data.
Page 172 Basic Theory of Operation: Controller Section The ARM controller core of the OMAP processor handles the power up sequence of all devices, including firmware upgrades, and all operating system tasks that are associated with FLASH and SDRAM memories and user interface communication. The FLASH memory (64 MB) is required to store the firmware, tuning, and Codeplug settings, which upon initialization get read and stored into SDRAM (32MB) for execution.

Page 268: Radio Description
® FLASHport The ASTRO APX1000 radio utilizes Motorola’s FLASHport technology. FLASHport makes it possible to add software that drives the radio’s capabilities both at the time of purchase and later on. Previously, changing a radio’s features and capabilities meant significant modifications or buying a new radio.
Page 269: Chapter 2 Basic Maintenance
General Maintenance In order to avoid operating outside the limits set by the FCC, align the ASTRO APX 1000 radio’s reference oscillator every time the radio is taken apart, or once per year, whichever comes first. (See Section 6.5.1).
Page 270 Basic Maintenance: Safe Handling of CMOS and LDMOS Devices • The APX 1000 radio has a vent port that allows for pressure equalization in the radio. Never poke this vent with any objects, such as needles, tweezers, or screwdrivers. This could create a leak path into the radio and a u t i o n the radio’s splash protection reliability will be lost.
Page 271: Chapter 3 Basic Theory Of Operation
Chapter 3 Basic Theory of Operation This chapter discusses the basic operational theory of the ASTRO APX 1000 radio. The ASTRO APX 1000 radio, which is a single-band synthesized radio, is available in the 900 MHz (896–941 MHz) frequency band.

Page 273: Analog Mode Of Operation
Basic Theory of Operation: Analog Mode of Operation Analog Mode of Operation This section provides an overview of the analog mode receive and transmit theory of operation. 3.2.1 Receiving The RF signal is received at the antenna and is routed through the Harmonic Filter, followed by the Antenna Switch and finally the 15dB Step Attenuator IC.
Page 274 Basic Theory of Operation: Analog Mode of Operation 3.2.1.3 Analog To Digital Converter The ADC IC's front end down converts the first IF to a second IF, a 2.25 MHz signal. The second IF is sampled at 18 MHz, a signal generated by an integrated clock synthesizer. The sampled signal is decimated by a factor of 900 to 20 kHz and converted to SSI format at the ADC's output.
Page 275: Digital (Astro) Mode Of Operation
Basic Theory of Operation: Digital (ASTRO) Mode of Operation Digital (ASTRO) Mode of Operation In the ASTRO (digital) mode of operation, the transmitted or received signal is limited to a discrete set of frequency deviation levels. The receiver handles an ASTRO-mode signal identically to an analog-mode signal, up to the point where the DSP decodes the received data.
Page 276 Basic Theory of Operation: Controller Section The ARM controller core of the OMAP processor handles the power up sequence of all devices, including firmware upgrades, and all operating system tasks that are associated with FLASH and SDRAM memories and user interface communication. The FLASH memory (64 MB) is required to store the firmware, tuning, and Codeplug settings, which upon initialization get read and stored into SDRAM (32MB) for execution.

Page 374: Radio Description
® FLASHport The ASTRO APX 2000/ APX 4000 (Two Knobs) radio utilizes Motorola’s FLASHport technology. FLASHport makes it possible to add software that drives the radio’s capabilities both at the time of purchase and later on. Previously, changing a radio’s features and capabilities meant significant modifications or buying a new radio.
Page 375: Chapter 2 Basic Maintenance
Chapter 2 Basic Maintenance This chapter describes the preventive maintenance and handling precautions. Each of these topics provides information vital to the successful operation and maintenance of the radio. General Maintenance In order to avoid operating outside the limits set by the FCC, align the ASTRO APX 2000/ APX 4000 (Two Knobs) radio’s reference oscillator every time the radio is taken apart, or once per year, whichever comes first.
Page 376 Basic Maintenance: Safe Handling of CMOS and LDMOS Devices • The APX 2000/ APX 4000 (Two Knobs) radio has a vent port that allows for pressure equalization in the radio. Never poke this vent with any objects, such as needles, tweezers, or screwdrivers. This could create a a u t i o n leak path into the radio and the radio’s submergibility will be lost.
Page 377: Chapter 3 Basic Theory Of Operation

Page 379: Analog Mode Of Operation
Basic Theory of Operation: Analog Mode of Operation Analog Mode of Operation This section provides an overview of the analog mode receive and transmit theory of operation. 3.2.1 Receiving The RF signal is received at the antenna and is routed through the Harmonic Filter, followed by the antenna Switch and finally the 15dB Step Attenuator IC.

ΣΔ ADC Filter Rx LO DIG_CTRL_ATTH 18Mhz Abacus III To GPS Diplexer Figure 3-4. Receiver Block Diagram (700/800 MHz) 3.2.1.1 GPS The GPS signal is tapped at the antenna port via a series resonant network (diplexer) which provides a very low capacitive load to the transceiver.
Page 381 Basic Theory of Operation: Analog Mode of Operation 3.2.1.4 700/800 MHz Front-End From the 15 dB Step Attenuator, a 700/800 MHz band signal is routed to the first band SPST switch which selects the 700 or the 800 band signal and routes it to the appropriate first pre-selector filter. A second band select switch selects the output of the appropriate filter and applies it to an LNA followed by a similar pre-selector filter/ band-select switch circuit.
Page 382 Basic Theory of Operation: Analog Mode of Operation 3.2.2 Transmitting When the radio is transmitting, microphone audio is digitized and then processed by the DSP and sent to the Trident IC (see Figure 3-6, Figure 3-7 Figure 3-8) via the SSI interface. The Trident IC processes the SSI data for application to the voltage controlled oscillator as a modulation signal.

Page 384: Digital (Astro) Mode Of Operation
Basic Theory of Operation: Digital (ASTRO) Mode of Operation Digital (ASTRO) Mode of Operation In the ASTRO (digital) mode of operation, the transmitted or received signal is limited to a discrete set of frequency deviation levels. The receiver handles an ASTRO-mode signal identically to an analog-mode signal, up to the point where the DSP decodes the received data.
Page 385 Basic Theory of Operation: Controller Section The ARM controller core of the OMAP processor handles the power up sequence of all devices, including firmware upgrades, and all operating system tasks that are associated with FLASH and SDRAM memories and user interface communication. The FLASH memory (64 MB) is required to store the firmware, tuning, and Codeplug settings, which upon initialization get read and stored into SDRAM (32MB) for execution.
