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. But now, similar to how a computer can be loaded with different software, the radio’s features and capabilities can be upgraded with FLASHport software.

Chapter 2 Basic Maintenance

Caution

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.

2.1 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. (See Section 6.5.1). Periodic visual inspection and cleaning is also recommended.

2.1.1 Inspection

Check that the external surfaces of the radio are clean and that all external controls and switches are functional. A detailed inspection of the interior electronic circuitry is not needed.

2.1.2 Cleaning

The following procedures describe the recommended cleaning agents and the methods to be used when cleaning the external surfaces of the radio. External surfaces include the housing assembly and battery case. These surfaces should be cleaned whenever a periodic visual inspection reveals the presence of smudges, grease, and/or grime.

The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild dishwashing detergent in water.

Use all chemicals as prescribed by the manufacturer. Be sure to follow all safety precautions as defined on the label or material safety data sheet.

The effects of certain chemicals and their vapors can have harmful results on certain plastics. Aerosol sprays, tuner cleaners, and other chemicals should be avoided.

The detergent-water solution should be applied sparingly with a stiff, non-metallic, short-bristled brush to work all loose dirt away from the radio. A soft, absorbent, lintless cloth or tissue should be used to remove the solution and dry the radio. Make sure that no water remains entrapped near the connectors, cracks, or crevices.

2.2 Safe Handling of CMOS and LDMOS Devices

Complementary metal-oxide semiconductor (CMOS) and Laterally Diffused Metal Oxide Semiconductor (LDMOS) 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 low-humidity conditions.

Page 34

2-2 Basic Maintenance: Safe Handling of CMOS and LDMOS Devices

Caution

• 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 leak path into the radio and the radio’s submergibility will be lost.

• The pressure equalization vent is located adjacent to the battery contact opening of the main chassis. Never touch the equalization vent. Ensure that no oily substances come in contact with this vent.

• The APX 2000/ APX 4000/ APX 4000Li radio is designed to be submerged to a maximum depth of six (6) feet, with a maximum submersion time of 2 hours per U.S. MIL-STD. Exceeding either maximum limit may result in damage to the radio.

If the radio battery contact area has been submerged in water, dry and clean the radio battery contacts before attaching a battery to the radio. Otherwise, the water could short-circuit the radio.

If the radio has been submerged in water, shake the radio briskly so that any water that is trapped inside the speaker grille and microphone port can be removed. Otherwise, the water will decrease the audio quality of the radio.

Page 35

Chapter 3 Basic Theory of Operation

For radios with 900 MHz, they support analog operation (12.5 kHz only), ASTRO mode (digital) operation (12.5 kHz only), and Phase 2 TDMA mode (12.5 kHz only).

NOTE: The APX 2000 M1.5, APX 4000Li M1.5 and APX 4000Li M2 radio do not support any Global

Positioning System (GPS), Bluetooth, MACE and Accelerometer functions. As such, disregard all references to the functions mentioned above in “Chapter 3 Basic Theory of

Operation”.

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. The diplexer circuitry provides rejection to radio band signals up to ~1GHz which serves as isolation between the radio RF and GPS signal paths. The GPS signal is filtered though a GPS SAW filter - LNA – Saw filter chain before going into the TI GPS IC for processing.

3.2.1.2 VHF Front-End

From the 15 dB Step Attenuator, a VHF signal is routed to the first pre-selector filter followed by an LNA and a second pre-selector filter. Both filters are discrete and tunable designs and are used to band limit the incoming energy and suppress known spurious responses such as Image and the ½ IF spur. The output of the second pre-selector filter is applied to the RF port of the Mixer IC. The Mixer IC is also excited by a Local Oscillator (LO) signal at the LO port to down-convert the RF signal to a

109.65 MHz intermediate frequency (IF). The down converted IF signal is passed through a crystal filter which drives the input of the Abacus 3 Analog to Digital Converter IC (AD9864).

3.2.1.3 UHF1/UHF2 Front-End

From the 15 dB Step Attenuator, a UHF1/UHF2 signal is routed to the first pre-selector filter followed by an LNA and a second pre-selector filter. Both filters are discrete and tunable designs and are used to band limit the incoming energy and suppress known spurious responses such as Image and the ½ IF spur. The output of the second pre-selector filter is applied to the RF port of the Mixer IC. The Mixer IC is also excited by a Local Oscillator (LO) signal at the LO port to down-convert the RF signal to a 109.65 MHz intermediate frequency (IF). The down converted IF signal is passed through a crystal filter which drives the input of the Abacus 3 Analog to Digital Converter IC (AD9864).

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. The signal is then routed to a second LNA whose output is applied to a discrete image filter. Both preselector filters are Surface Acoustic Wave designs used to band limit the received energy and suppress known spurious responses such as Image and the ½ IF spur. The output of the discrete image filter is applied to the RF port of the Mixer IC. The Mixer IC is also excited by a Local Oscillator (LO) signal at the LO port to down-convert the RF signal to a 109.65 MHz intermediate frequency (IF). The down converted IF signal is passed through a crystal filter which drives the input of the Abacus 3 Analog to Digital Converter IC (AD9864).

3.2.1.5 900 MHz Front-End

From the 15 dB Step Attenuator, the 900 MHz band signal is routed to the pre-selector filter. The output of the prefilter is applied to the first LNA followed by a similar filter as the pre-selector filter. The signal is then routed to a second LNA whose output is applied to a discrete image filter. Both pre and post selector filters are Surface Acoustic Wave designs used to band limit the received energy and suppress known spurious responses such as Image and the ½ IF spur. The output of the discrete image filter is applied to the RF port of the Mixer IC. The Mixer IC is also excited by a Local Oscillator (LO) signal at the LO port to down-convert the RF signal to a 109.65 MHz intermediate frequency (IF). The down converted IF signal is passed through a crystal filter which drives the input of the Abacus 3 Analog to Digital Converter IC (AD9864).

3.2.1.6 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. The Serial Synchronous Interface (SSI) serial data waveform is composed of a 16 bit in-phase word (I) followed by a 16 bit Quadrature word (Q). A 20 kHz Frame Synch and a 1.2 MHz clock waveform are used to synchronize the SSI IQ data transfer to the Digital Signal Processor IC (OMAP) for post-processing and demodulation.

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 and 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.

3.2.2.1 VHF Transmit

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. The signal now goes through the antenna switch which routes the power to the harmonic filter which will filter out the harmonics of the carrier signal and then passes through a directional coupler. The Log Amp power detector Monitors the output of the directional coupler and adjusts the control voltages to the driver amplifier and final power amplifier. Finally, the RF signal is routed to the main antenna.

Basic Theory of Operation: Digital (ASTRO) Mode of Operation 3-9

3.3 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. In the ASTRO receive mode, the DSP uses a different algorithm to recover data.

In the ASTRO transmit mode, microphone audio is processed identically to an analog mode, with the exception of the algorithm the DSP uses to encode the information. Using this algorithm, transmitter FM deviation is limited to discrete levels.

3.4 Controller Section

The controller section (See Figure 3-11.) comprises of five functional sections that are split among two boards, which are the main and keypad boards. The main functional section consists of a dual core ARM and DSP controller, an encryption processor (MACE), Flash memory, and a Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM) and CPLD for GPIO expander multiple clock generation and SSI interface for the radio system. The Power and Clocks section includes a power management IC (MAKO) and various external switching regulators, and three clock sources (12 MHz and 24.576 MHz) from which all other controller digital clocks are derived. The Audio section has a CODEC and a class-D audio power amplifier that provides the radio with a microphone and speaker design. The User Interface section provides communication and control to the main Liquid Crystal Displays (LCD) on the radio, as well as a keypad and a side connector interface conforming to GCAI (Global Communications Accessory Interface) specifications. The GPS and Bluetooth section comprises of a Global Positioning Satellite(GPS) and Bluetooth combo chipset on the main board, and an AVR Bluetooth controller IC, SDRAM, LF wakeup IC and Accelerometer IC on the keypad board. The MACE IC is located on the keypad board.

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. The ARM and DSP core jointly control and configure audio, wireless and RF devices linked to the Serial Peripheral Interface (SPI) and Synchronous Serial Interface (SSI) buses to enable radio FM and optional wireless communication protocols. For encryption, a separate ARM processor is used (MACE) to encode and decode encryption packets coming in from the main OMAP processor through the SSI interface. Its firmware is flashed via the main processor during an upgrade request to its internal FLASH memory. The MACE encryption processor is located on the keypad board.

The power and most clocks to the controller devices are provided by the MAKO IC and external switching and linear regulators on board. A Complex Programmable Logic Array (CPLD) IC divides the 24.576 MHz clock from MAKO to source OMAP's 32 kHz Real Time Clock, and MACE's 4 MHz main clock. OMAP's main clock is supplied externally from an on board 12 MHz crystal.

The radio has two internal microphones and an internal speaker, as well as available microphone and speaker connections for external accessories. The internal 4 Ohm speaker is located on the same side as the main display and keypad of the radio. The internal speaker is driven by a Class D audio amplifier located on the main board that is capable of delivering a rated power of 0.5 W. The external accessory speaker is driven by a Class AB audio amplifier on the MAKO IC that is capable of delivering 0.5 W of power into a 16 Ohm as a minimum load. Both speaker paths use the CODEC for volume control and to convert the audio signal from digital to analog. Both internal and external microphones use the CODEC's ADC to deliver digital audio samples to the DSP controller.

The user interface block consists of a main display, a keypad, top controls and the accessory side connector. The side connector (Universal Connector) provides audio, USB, RS232 communication for accessories. All signals to and from the connector go through the internal keypad board before reaching the microcontroller and other devices on the main board.

The radio also has integrated feature of Global Positioning System (GPS) and Bluetooth with Mandown feature (depending on radio model) (see Figure 3-12). The GPS and Bluetooth Combo RF chipset (NL5500) is located on the Main board together with the GPS/RF Diplexer circuitry and Bluetooth Front-End circuitry. The GPS receiver section of the GPS/BT combination IC interfaces with the OMAP processor through a dedicated UART port. The GPS receiver also has a dedicated reset controlled solely by the OMAP processor. The GPS/Bluetooth IC (NL5500) taps the GPS signal from transceiver path and processes the location information before relaying to the OMAP processor via UART lines. The clock supplies to NL5500 included a 26MHz TCXO and 32kHz clock from CPLD.

The radio also has the ability to connect to a wireless Bluetooth audio headset. This feature is implemented using a combination Bluetooth/GPS integrated circuit (NL5500 IC) located on the Main board. An optional accessory headset can connect using a low-data rate GFSK modulated signal hopping on 79 x 1 MHz wide Bluetooth channels from 2402 MHz to 2480 MHz in the ISM band. Each APX accessory that is capable of Bluetooth communication will have its own unique Bluetooth address. Bluetooth uses a frequency hopping spread spectrum (FHSS) technique to spread the RF power across the spectrum to reduce the interference and spectral power density. The frequency hopping allows the channel to change up to 1600 times a second (625 μs time slot) based on a pseudo random sequence. If a packet is not received on one channel, the packet will be retransmitted on another channel. The Bluetooth IC sends data to the AVR32 processor that is also located on the keypad board over an HCI UART link. The AVR32 processor communicates to the OMAP processor on the main board through a dedicated USB port.

The Bluetooth feature is accompanied by a Low-Frequency (LF) detection circuit that is also located on the keypad board. The LF circuit provides the ability of a secure pairing connection with a Bluetooth accessory. Once a radio has the Bluetooth feature enabled, a user can tap their LF enabled Bluetooth audio accessory with the radio at the pairing spot to establish a secure Bluetooth connection. The LF circuit uses a 125 kHz radiated signal to communicate the secure pairing information between the Bluetooth accessory and low-frequency receiver. The low-frequency receiver is programmed by the AVR32 processor through a dedicated SPI bus and transfers the pairing data through a dedicated UART.

There is a digital accelerometer on the keypad board that detects the 3-axis force of gravity which can be used to determine the radio's orientation. The accelerometer's position is communicated to the AVR32 processor through a SPI bus.

Caution

This chapter describes both receiver and transmitter radio alignment procedures.

6.1 Test Setup

A personal computer (PC) and tuner software are required to align the radio. Refer to the applicable manual for installation and setup procedures for the software. To perform the alignment procedures, the radio must be connected to the PC and to a universal test set. The radio alignment test setup is shown in Figure 6-1.

Figure 6-1. Radio Alignment Test Setup

These radio alignment procedures should only be attempted by qualified service personnel. Failure to perform alignment procedures properly may result in seriously degraded radio or system performance.

6.2 Tuner Main Menu

Select Tuner from the START menu by clicking Start › Program Files › Motorola › ASTRO 25 Products › ASTRO 25 Tuner. To read the radio, use the File › Read Device menu or

click on . Figure 6-2 illustrates how the alignment screens are organized. To access a screen, double-click on the desired screen name in the Tuner menu.

IMPORTANT: Tuning should follow the order of the Tuning tree view in descending

6.3 Softpot

The alignment screens introduce the concept of the “softpot,” an analog SOFTware-controlled POTentiometer used for adjusting all transceiver alignment controls.

Each alignment screen provides the ability to increase or decrease the softpot value by using a slider, or by entering the new value from the keyboard directly into the box. The slider bar indicates the current softpot value; see Figure 6-3.

Figure 6-2. Tuner Software Main Menu

order from top to bottom

DO NOT switch radios in the middle of any alignment procedure. Always left-click the Close button on the screen to return to the Main Menu screen before disconnecting the radio. Improper exits from the alignment screens might leave the radio in an improperly configured state and result in seriously degraded radio or system performance.

Page 63

Radio Alignment Procedures: Softpot 6-3

Caution

Figure 6-3. Typical Softpot Screen

Adjusting the softpot value sends information to the radio to increase (or decrease) the voltage in the corresponding circuit. For example, left-clicking the UP spin button in the New Softpot Value scroll box on the Reference Oscillator screen instructs the radio’s microcomputer to increase the voltage across a varactor in the reference oscillator, which increases the frequency.

In ALL cases, the softpot value is just a relative number corresponding to a digital-to-analog (D/A) generated voltage in the radio.

Perform the following procedures in the sequence indicated.

NOTE: Some of the following screens may vary depending upon the radio under test and the version

of tuner software you are using. Refer to the software’s online help.

When keying the radio during a test, always dummy load.

6.5.1 Reference Oscillator Alignment

Adjustment of the reference oscillator is critical for proper radio operation. Improper adjustment will result not only in poor operation, but also in a misaligned radio that will interfere with other users operating on adjacent channels. For this reason, the reference oscillator should be checked every time the radio is serviced, or once a year, whichever comes first. The frequency counter used for this procedure must have a stability of 0.1 ppm (or better).

NOTE: Reference oscillator alignment is required after replacing (or servicing) the transceiver board.

6.5.5 Transmit Deviation Balance Alignment

This alignment procedure balances the modulation contributions of the low- and high-frequency portions of a baseband signal. Proper alignment is critical to the operation of signalling schemes that have very low frequency components (for example, DPL) and could result in distorted waveforms if improperly adjusted.

This procedure needs to be performed at multiple frequencies to allow for proper alignment across the entire RF band. The RF band is divided into frequency zones with a calibration point (value) in each zone.

NOTE: This alignment is required after replacing (or servicing) the main board.

Proper alignment requires a modulation analyzer or meter with a frequency response to less than 10 Hz modulating frequency. The modulation analyzer settings during this test should be set for average deviation, a 15 kHz low-pass filter, no de-emphasis, and no high-pass filter, if these settings are supported.

This alignment can be done with either the R-2670 Communication Analyzer or the 8901_ Series Modulation Analyzer. The method of choice is the R-2670 analyzer.

1. Initial setup using the R-2670 Communication Analyzer:

- Connect a BNC cable between the “DEMOD OUT” port and the “VERT/SINAD DIST/DMM COUNTER IN” port on the R-2670.

-Press the SPF key on the R-2670 to display the “SPECIAL FUNCTIONS MENU.” Move the cursor to “High Pass,” and select 5 Hz on the soft key menu. Select 20 kHz for the “Low Pass” setting.

- In the “RF Control” section of the R-2670, move the cursor to the “B/W” setting and select “WIDE +/- 100 kHz” on the soft key menu.

- Place the R-2670 cursor in the “Display” zone. Select “AC VOLTS” on the soft key menu. Move the cursor to the “Range” setting and select “AUTO.”

2. Initial setup using the 8901_ Series Modulation Analyzer:

-Press the FM MEASUREMENT button. (The “Error 0input level too low” indication is normal until an input signal is applied.)

- Simultaneously press the Peak – and Peak + buttons. Both LEDs on the buttons should light.

- Press the 15 kHz LP filter key.

3. Select the TX Deviation Balance alignment screen. The screen indicates the transmit

frequencies to be used. See Figure 6-25, Figure 6-26, Figure 6-27, Figure 6-28 and

Figure 6-29.

4. In the "RF Control" section of the R2670, set the service Monitor to the desired frequency (as shown in the frequency list in the TX Deviation Balance alignment screen).

5. Left-click the PTT Tone: Low button.

6. Left-click the slider of the frequency selected (should be the same frequency as step 4).

7. Left-click the PTT Toggle button on the screen to make the radio transmit. The screen indicates whether the radio is transmitting.

8. Measure and Record the Low Tone Tx Deviation value from the 8901_ Series Analyzer or the AC voltage value from the R2670.

9. Left-click the PTT Tone: High button.

10. Adjust the softpot value until the measured deviation/voltage, when using the high tone, is within +/- 1.5% of the value observed when using the Low Tone.

Chapter 7 Encryption

This chapter provides procedures for using the encryption capability of your radio. The following procedures are outlined:

• Loading an encryption key

• Selecting an encryption key

• Selecting an Index

• Erasing an encryption key

7.1 Load an Encryption Key

Keys will be loaded from the KVL to the radio in either clear or encrypted form depending on the configuration of the CPS parameter "KVL – FIPS Level 3 Approved Mode". If the parameter is disabled, keys will be sent in clear form; if the parameter is enabled, keys will be sent to the radio in encrypted form.

NOTE: A KVL3000 Plus with software version R03.52.45 or greater must be used to load keys to a

radio with "KVL – FIPS Level 3 Approved Mode" enabled.

To load an encryption key:

1. Refer to the key-variable loader (KVL) manual for equipment connections and setup.

2. Attach the KVL to the radio. “KEYLOADING” is shown on the main display of a configured

radio. All other radio functions, except for power down, backlight, and volume, are locked out.

3. Refer to the KVL manual for how to load the encryption keys into the radio.

4. When the key is loaded successfully, you will hear:

• On single-key radios – a short tone.

• On multikey radios – an alternating tone.

The secure kits for APX 2000/ APX 4000 are identified by the following kit numbers:

7-2 Encryption: Multikey Feature

7.2 Multikey Feature

This feature allows the radio to be equipped with multiple encryption keys. It can support two or more encryption algorithms simultaneously (e.g., AES and DES-XL).

• Conventional Multikey – The encryption keys can be tied (strapped), on a one-per-channel

basis. In addition, the radio can have operator-selectable keys, operator-selectable indices, and operator-selectable key erasure. If talkgroups are enabled in conventional, then the encryption keys are strapped to the talkgroups.

• Trunked Multikey – If the radio is used for both conventional and trunked applications, strap

the encryption keys for trunking on a per- talkgroup or announcement group basis. In addition, a different key can be strapped to other features; for example, dynamic regrouping, failsoft, or emergency talkgroup. The radio can have operator-selectable key erasure.
