  • Page 13: Section 1 - General Information

    Operation of the SRP8000 Series is controlled by settings of the various software parameters. These operating parameters are stored as data in Flash EPROM and these data may be programmed into the radio using an external data programmer, allowing the SRP8000 Series to be customized to the requirements of a particular user.

  • Page 19: Charging The Battery

    GREEN LED Figure 2.2 Battery Charging Sequence The SRP8000 Series Portable Radio is supplied with batteries in their discharged state. Before using the radio, it is necessary to charge the battery using one of the approved battery chargers. This takes approximately one hour, after which the red LED changes to green.

  • Page 20: Fitting The Wrist Lanyard

    The antenna supplied with the radio is the correct length for the frequency band ordered and must be fitted to the mounting boss at the top of the radio (refer to Figure 2.3 step 3). As an option, an uncut antenna may be supplied which will cover a wide frequency band. In this case, the antenna must be cut to the transmitter centre frequency of the frequency band to be used.

    Fitting a Battery Figure 2.5 Fitting a Battery Locate the battery on the back of the radio with approximately 10mm of the nickel plated metal casting showing. Slide the battery up the radio. When the battery is fully in position, the catch will locate and lock. (Refer to Remove the Battery on page 4.1 for instructions on removing the battery).

  • Page 25: Section 3 - Technical Description

    VHF/UHF PORTABLE RADIO SECTION 3 - TECHNICAL DESCRIPTION INTRODUCTION The SRP8000 Series is a range of advanced portable radios using the latest modern technology to achieve a very high performance in a small size. Internally the radio consists of: Radio PCB A multi-layer assembly with components mounted both sides.

  • Page 26: Power Supplies And On/Off Control

    POWER SUPPLIES AND ON/OFF CONTROL The main power supply for the radio is the 7,2V battery which is connected directly to the PCB via the battery contacts on the rear of the radio. The power supply has five separate regulators supplying power to the following blocks (see Figure 3.2): VCO PSU +5,6V...

    RECEIVER Antenna Filter Figure 3.3 on page 3.5 is a block diagram of the receiver and the circuit diagram is shown in Figure 6.8. The antenna low pass filter (L104 to RX_ANT on Figure 6.9) isolates the receiver input during transmissions (D100 forward biased) whilst maintaining a low loss connection from the antenna in the receive state.

  • Page 30: Transmitter

    TRANSMITTER The transmitter block diagram is shown Figure 3.4 and the circuit diagram in Figure 6.9. The transmitter consists of a PA module taking its input from the frequency generation block, and feeding an antenna filter and switch. The transmit power is set by processor control of a DAC in the baseband chip IC701.

  • Page 31: Figure 3.5 Frequency Generation Block Diagram

    LOOP_FILTER and VCAP_BIAS, are compared and the difference between them determines the VCO frequency. Oscillator tuning is by varicap diodes D402 to D405 (receive oscillator) and D407 to D411 (transmit oscillator). Separate wideband VCOs (Rx first local oscillator - TR409, and Tx oscillator - TR413), but a common buffer amplifier (TR410, TR414) are used on all bands.
  • Page 32 The synthesizer, IC401, contains two synthesizer circuits. The second circuit is used for the generation of the receiver second local oscillator (output control signal AUX_CP). This removes the need for the alignment of this oscillator because the frequency is locked to the TCXO and allows its frequency to be varied to avoid potential interference.

  • Page 33: Control Processor System

    CONTROL PROCESSOR SYSTEM The heart of the control processor system consists of the following: H8/3002 Processor (IC600) 32KByte Static RAM (IC601) 512KByte Flash EPROM (IC602) MAX512CSD Triple 10-bit DAC (IC605). The processor controls and monitors the radio functions by a variety of types of digital and analogue interfaces.

  • Page 34: Baseband Audio And Signalling

    The analogue control interfaces are as follows: The processor generates and controls various analogue voltages for receiver and transmitter purposes. IC605 is a triple 10-bit DAC which the processor controls via a 3-wire serial bus. Two of the DAC outputs are used for receiver front-end tuning (RX_TUNE1, RX_TUNE3) and the third for TCXO XL400 frequency trimming.

  • Page 36: Signalling Facilities

    Signalling Facilities The baseband chip has facilities for CTCSS, SELCALL, DTMF and FFSK signalling. The way in which these signalling modes are controlled and how to they relate to the receive and transmit audio paths is described in the following sections. Figure 3.8 is referred to for receive signalling and Figure 3.9 for transmit signalling.

  • Page 39: Ext_Lsa, Ext_Lsb

    EXT_LSA, EXT_LSB The bridged audio loudspeaker outputs are capable of delivering 500mW into a 16Ω load. MIC1 The combined accessory detect and audio input line MIC1 allows the radio to detect what type of ancillary is connected and the ancillary status (such as key presses). Each ancillary has a ‘type’ resistor that sets up a unique voltage on this accessory detect line which is monitored by the comparator formed by IC801_A and its associated components.

  • Page 40: Mmi Display And Keypad (Not Fitted On Srp8010)

    The KEY_DET3 voltage generated by the different keys is as follows: If the PTT is pressed, KEY_DET3 voltage will still be at 0V If SIDE_KEY1 or SIDE_KEY2 is pressed, each side key generates a unique KEY_DET3 voltage by virtue of resistors in series with each key (R12, R11, R81) in combination with R15 If the ALARM key is pressed, analogue switch IC3 forces KEY_DET3 voltage to the same voltage as the AF_PSU.

Enter). The SRP8030 has 12 additional keys (supported by the daughter board) arranged as a DTMF keypad.

  • Page 42: Trickle Charger

    TRICKLE CHARGER The trickle charger uses a positive input on the RxD pin of the smart interface to power a current limited source feeding the battery, limiting the current to approximately 130mA. The charger is enabled by the thermistor in the battery pack, so it is inhibited if a battery pack is not fitted (this is necessary to prevent a voltage at the battery connector which could damage the radio when no battery is present).

  • Page 43: Section 4 - Servicing

    SRP8000 SERIES VHF/UHF PORTABLE RADIO SECTION 4 - SERVICING CAUTION Metal Oxide Semiconductors (MOS) are used in this equipment; therefore the following predictions should be strictly observed, otherwise the devices may become damaged. Device leads should always be in contact with a conductive material to avoid the build-up of static charges.

  • Page 44: Remove The Metal Frame Assembly

    Remove the Metal Frame Assembly (Refer to Figure 4.2) Use a small, flat bladed screwdriver to release the cast metal frame assembly from the bottom of the front casing. This action releases the radio PCB from the MMI PCB. Gently ease the frame assembly out of the front casing taking care not to damage the two flexi-circuits (lift the bottom of the frame so that it just clears the plastic casing, then gently slide the frame away from the top of the casing until it is released from the casing).

  • Page 45: Remove The Radio Pcb

    Figure 4.3 Removing the Metal Screen Remove the Radio PCB (Refer to Figure 4.4) Release the remaining flexi-circuit from the radio PCB as follows: Slide out the locking drawer of the PCB connector, SK6, (on the radio PCB). Use a very small flat bladed screwdriver.

  • Page 46: Remove The Speaker And Microphone

    Remove the Speaker and Microphone (Refer to Figure 4.5) Remove the speaker retaining clip. Lift the speaker / microphone assembly away from the front casing taking care not to damage the flexi-circuit. Figure 4.5 Removing the Speaker / Microphone Assembly Remove the MMI PCB (Refer to Figure 4.6) The MMI PCB is held in place by four plastic lugs on the front casing.

  • Page 47: Re-Assembly

    RE-ASSEMBLY Re-assembly is the reverse of dis-assembly. However: Examine the various seals before re-assembly and replace with new items if necessary. Slight outward deflection of the case walls will ease re-assembly of the MMI PCB behind the retaining lugs. Care must be taken when reconnecting the flexi-circuits to ensure that they are correctly aligned before pressing home the locking drawers on the connectors.
