SRM9000X8 800MHz SERVICE MANUAL

Warnings and Cautions

Compliance with RF Energy Exposure Standards: To minimise exposure to RF fields during equipment service and repair, the antenna terminal of the SRM9000 radio should be connected to a suitable non-radiating RF load when the transmitter is in use.

SRM9000 radio equipment is to be connected

with a 24-volt supply, an approved 24V/12V converter must be used. The supply must not be

taken from a 12V tap on the battery.

To avoid RF injury, do not touch the Antenna when the Transmitter is in use.

Double-fused 12V Supply Leads, Antenna cables and Speaker wiring is to be routed as far away

as possible from gas or fuel lines or any electronic control device. The radio transceiver and

antenna are to be mounted as far away as possible from these devices and their cabling.

Equipment is to be installed, by a competent person, in accordance with the requirements of

local radio communications authorities and/or Health and Safety regulations.

Post installation checks should be performed to ensure that there is no effect on the operation of

the vehicle’s electronics.

WARNING

only

to 12-volt negative earth systems. In vehicles

WARNING

Do not operate your radio, without a handsfree kit, whilst driving a vehicle.

WARNING

Do not operate your radio in an explosive atmosphere. Obey the “Turn Off Two-way Radios”

signs where these are posted, e.g. on a petrol station forecourt.

Caution

During disassembly and assembly, refer to Torque Settings in Section 1.6

Caution

Customer configuration files should be saved prior to any alignment adjustments.

Preparing the radio for alignment will erase from the radio all customer PMR configuration data

(channel, signalling information etc). The only data retained by the Alignment Tool is the factory

alignment data for the radio (DAC settings for Tx power, front-end tuning etc).

SRM9000X8 800MHz SERVICE MANUAL

1. INTRODUCTION

1.1 GENERAL

The SRM9000X8 800MHz mobile transceiver is designed for PMR operation in analog systems or P25 in digital systems.

The SRM9000X8 transceiver can be used with either the SRM9022 Graphics Display Handset or the SRM9030 System Level Remote Control Head with Alpha capability.

1.2 S

This manual provides technical specifications, description and servicing details for the SRM9000 mobile radio transceiver.

COPE

1.3 DESCRIPTION

The design concept utilises wide band techniq ue s fo r RF tr ansmit and receive circuitry with digital signal processing of analog or digital modulatio n a nd dem od ula tion. Electronic tuning is used throughout the mobile to eliminate manual tuning and level adjust ment.

A Digital Signal Processor (DSP) and a Programmable Gate Array (PLA) are used with other dedicated dev ices in the SRM9000 to perform the following fu nctions under software control:

• Frequency Synthesis of all operating frequencies.

• Modulation and demodulation of 12 . 5kHz o r 25 kHz FM signals or P25 digital modulation on a per

channel basis.

• Modem functionality for specified d ata modulation schemes.

• Filtering, pre-emphasis, de-emphasis, limi ting, compression, muting, CTCSS, Selcall or any other

frequency or level dependent signal modification.

• Serial communications with the Control Ancillaries and Alignment Tool. Tuning Control data for Tx and Rx.

•

The SRM9000 basic Transceiver comprises a rugged extruded aluminium sleeve, which houses a single printed circuit board assembly and provides all heatsink requirements. The sleeve housing is closed at each end by highimpact plastic end caps; all cable ports and mechanical interfaces are sealed against moisture and dust ingress.

The PCB assembly comprises a single, multi-layer PCB cont ain i ng all the RF and control circuitry. The PCB seats on an extruded aluminium tray that slides into the outer aluminium sleeve where it is secured with screws accessed from the outside of the case. Provision is made under the main PCB tray assembly for additional hardware options as well as optional a ccessor ies p l ug ged directly into the main PCB.

There are two installation methods available for the SRM9000. The outer aluminium extrusion has side flanges that allow the mobile to be bolted directly to any flat surface in the vehicle. A quick release cradle is also available.

Software Versions and Naming

There are various associated items of Software (SW) required for the SRM9000 radio and programmer to operate. This section simply defines the naming rules of the SW files to allow identification and conformity. This allows different versions of SW to be distributed and co-exist without confusion.

The SRM9000 Transceiver has three items of SW fo r digital and analog PMR, Trunking and Alignment. The 9022 Controller Mic/Handsets has one SW file for its PIC and the 9030 Control Head has two SW files for its

Flash and EEPROM.

1.4.1

Basically the Filename Structure is defined as follows:

• 2 character Applicatio n cod e

• 2 or 3 character SW Type code

• 3 character version number

• File Extension as required.

eg.

9ep_533.bin 9es_533.bin 9ecf101.hex 9ece101.hex

SRM9000X8 800MHz SERVICE MANUAL

1.4.4

This is a 3-digit number allocated by Engineering to identify the SW version. e.g. 103 = Version 1.03

1.4.5

The Programmer SW does not follow the above ru les as it is a PC based Program and its version number can be easily identified by starting th e SW . Later releases of SW will be backward compatible, unless deliberately not so, in which case a different directory structure/path may be implemented.

1.4.6

When a configuration is downloaded to the Transceiver, the Programmer performs a brief check on the SW currently installed in the radio. If a later version of SW exists (on PC hard-disk) then the Programmer will prompt the user with the following message :

NOTE. As early versions of FPP cannot recognise a more recent revision of the radio, it is important that the latest FPP version is downloaded from http://www.tmcradio.com.

SRM9000X8 800MHz SERVICE MANUAL

1.4.8

The SRM9000 Transceiver software is split into th e following separate modules:

When the Transceiver starts, it basically performs the following steps:

If the Mainline Software cannot be lo ad ed, or a Job file configuration has not been loaded (e.g. non-existent or checksum fail) then execution switche s to Backup Software until the error is corrected (e.g. by FPPing the radio).

There are three states that the radio can configure after switch-on:

Transceiver SW Description, Start-up and Backup-Software

• Bootloader and Backu p Software

• Start-Up Soft war e

• PLA and PLA-Backup Software

• Mainline PMR Software

• Initial execution starts with the Bootloader code, which attempts to load the Start-Up Software (if Start-

Up checksum is bad, then the Backup Software is lo ad ed .)

• Start-Up Software then do wnloads the PLA code (or PLA-Backup code if PLA checksum is bad) to the PLA device. If both PLA and PLA-Backup checksu ms are ba d then the radio is not operational and serial communication is not possible.

• Start-Up Soft war e then reads the On/Off switch plus Ignition-Sense lines and compares t he se with saved parameters to determine if the rad i o sho uld be continue to power-up or switch itself off again.

• Start-Up software t h en attempts to load PMR Mainline Software (dependent on save d pa ra meter) and switches execution to complete the powe r-up process and start normal operation.

• Mainline PMR Softw are (no rma l po wer-up) If the radio does not have a vali d Jo b file configuration loaded, then it will display a “No PMR Cfg”.

• Start-Up Software (characterised by “Alignment Mode” shown on the display). This is also t he cod e that is running when the radio is being aligned using the Alignment Tool.

• Backup Software (via various paths from above.)

1.4.9

A “WAILING SIREN” sound is emitte d from the Loudspeaker while the radio is running in Boot Backup Softw are . In this mode the FPP can be used to re-load a Jo bf ile, or re-load Start-Up or Mainline Operating Software.

Simply writing a Jobfile to the radio should allow the FPP to determine and update the offending software – however there may be instances where the FPP cannot determine this and the Start-Up and Mainline Software should be updated manually. This can be do ne using the FPP : Upgrade_Software : Get_File … then Download. Both Start-Up Software (filename = 9es_xxx.bin) and Mainline PMR (9ep_xxx.bin) should be loaded if the FPP cannot automatically fix the problem. The wailing siren s hould stop once the problem is fixed.

Note: Should these steps fail to restore the set and the Wailing Siren cease, the radio will need to be returned to

Wailing Siren (Boot-up Software Corrupted)

a Level 3 Service Centre for FLASH repl ace ment.

1.5 ADJUSTMENT AND ALIGNMENT

There are no manual internal adjustments in the SRM9000. Re-programming and alignment is done using software tools with the PCB installed in its chassis. For servicing, the radio PCB can be operated outside the chassis provided that a temporary heatsink is fitted under the transmitter PA module for transmitter servicing and that the receiver audio output be kept below 100mW for receiver servicing. Radio performance is only slightly affected by operating without the outer sleeve but there will be some change to performance when the metal cans are removed from the RF sections of the board.

On re-assembly, the PA module should be checked for a thin layer of heat-conducting paste. If this is missing or dried-out, it should be replaced prior to re-assembly.

HASSIS ASSEMBLY

Important Note!

1.6.1

Assembly of 'Chassis' (Inner Extrusion) to 'Outer Extrusion': 1.4 Nm (PA x 2), 1.25Nm (Others x 3) Assembly of 'Front' and 'Rear' end-caps to 'Outer Extrusion': 1.4 Nm.

1.6.2

Just enough thermal compound should be applied to the PA tray to provide good thermal contact with the chassis. Note. If thermal compound is old and difficult to spread, it should be discarded.

1.6.3

The Inner extrusion should initially be ne ste d t og et h er with the PCB and then the assembly slid into place within the outer extrusion.

Positioning the inner extrusion upwards by hand, it is then important to insert all screws by hand and ensure they have been fully inserted through the PCB, thereby locating the assembly correctly.

Whilst holding the inner extrusion upwards to ensure the assembly does not twist, lightly torque up the centre screw of the row of three followed by the PA module mounting screw towards the middle of the chassis.

The remaining screws can then be screwed up to full torque followed by re-torque of the first two screws.

3. TECHNICAL DESCRIPTION

3.1 RECEIVER

Refer to Figure 3-1.

3.1.1

The receiver input signal fr om the antenna passes through the h armonic filter and antenna T/R switch. Wi th the mobile in receive mode, diodes D580, D582 and D583 in the antenna switch are reverse biased allowing the receiver input signal to be co upled throug h to the rec eiver fron t-end with minimal los s. The overall inser tion loss of the harmonic filter and switch is approximately 0.8dB.

The signal is then fed through SAW bandpass filte r (Z400) to the input of the RF amplifier (Q404). The SAW filter bandpass covers 851MHz to 870MHz. The RF amplifier stage comprises a low noise transistor amplifier (Q404) that is compensated to maintain good linear ity and low noise matc hing; this p rovides excellen t intermodulatio n an d blocking performance across the full operating range. The overall gain of the front-end is approximately 9dB.The RF amplifier has constant cur rent bias controlled by Q402. The output of the RF amplifier is coupled through a varactor-tuned bandpass filter comprising of two ceramic resonators (Z430 and Z431). The varactors have individual PWM tuning voltages, TU NE 1 and TUNE 2, that are derived from PLA (U300). The tuning volta ges values for the filter varactors are controlled by the alignment data stored in the radio. The DSP processes these data to optimise the filter tuni n g for each of the programmed channel frequencies.

A negative bias supply originates from the DSP/PLA as a PWM signal for the two filter tuning voltages for the specific channel frequency selected. The PWM signal, which is dependent on channel frequency and tuning, passes through level shifting transistors Q451 to Q454, where it is converted to a negative voltage in the range

-0.5V to -11.5V. The -12.0V rail for the level translators is generated by U904E/F, with D903 to D906 providing the required voltage multiplication.

3.1.2

The output of the ceramic resonator pair is then fed into U441, a high performance passive mixer that converts the RF signal to a IF of 45MHz. The first local oscillator injection level is typically +8dBm with high side injection.

Following the mixer is a IF amplifier (Q461) that provides approximately 15 dB of gain and, in association with its output circuitry, presents the required load conditions to the 4 pole 45MHz crystal filters Z471A/Z471B.

The crystal filters provide part the total required selectivity for adjacent channel operation with the remaining selectivity provided by a DSP bandpass filter algor ithm.

Front End Filters and RF Amplifier

First Mixer and IF Section

3.1.3

Additional IF gain of approximately 44dB occurs in U481, which is a dedicated IF AGC Amplifier and Quadrature Demodulator. The AGC voltage for U481 is derived from the RSSI function of the DSP. The onset of AGC operation occurs when RF input s ignal level at the antenna connector exce eds -90dBm and can reduce the gain by approximately 100dB for strong signals.

Conversion of the 45MHz IF signal to I and Q baseband signals is carried out by the demodulator section of U481. The 90MHz second local oscillator signal for U481 is generated by VCO Q730, which is phase locked by the PLL CPIF output of U721, via feedback signal FINIF.

3.1.4

The baseband audio from the IQ Demodulator is applied to a diffe rential amplifier (U941A/ U941B) that converts the balanced demodulator I and Q output signals to unbalanced inputs for the CODEC (U800).

All receiver audio processing and filtering functions are performed by the CODEC und er the control of the DSP. The receiver I and Q analog baseband signals are converted to digital signals by the CODEC ADC before being applied to a series of digital filters that provide the final stages of adjacent channel filtering, high pass and low pass audio filtering, mute noise processing, and volume control level for narrow and wideband operation. The fully processed signal is then converted to an analog audio signal by the CODEC DAC and then applied to conventional audio amplifiers (U803A/B) an d the loudspeaker amplifier (U805).

In addition, Discriminator Audio is derived from the second CODEC output channel and then amplified by U802A after which it is appl ied to one of the radio I/O conn ector s for op tion p ur pos es. D isc rimin ator Audio is a pr ese t level set by the FPP and is independent of squelch operation.

There are two speaker options available, a half-bridged configuration using a speaker across balanced output SPKR OUT1 and 2, which provides an audio outp ut level of up to 4 watts into 4 ohms. The other option is a full bridge configuration using a high power speaker across SPKR OUT1 and 2 and providing an audio output level of up to 10 watts into 8 ohms; this high power option is enabled by adding 0 ohm resistor, R85 9. The carrier and signalling mute functions are performed by Q810/Q811/Q813 under DSP control. De-emphasis to the audio PA (U805) is performed by R861 and capacitor C872. Flat audio is provided to connector S1-6 via amplifier U803A.

3.2.1

Receiver Audio Processing

RANSMITTER

Drivers and PA Stages

The carrier frequency for the transmit ter is generated by combining the receiver first LO with the receiver second LO in TX mixer (U650).

The output of the mixer (U650) is fed into a broadband amplifier (U670) via a tuned filter comprising of varactors D660 and D661, to reduce the unwanted mixer products. The tuning voltage for the filter varactors, TUNE 1N, is derived from level translators Q451 and Q452. U670 amplifies signals from 806MHz to 825MHz for two frequency simplex applications and 851MHz to 870MHz f o r tu rnaround operation. The output of U670 connects to a diode switch arrangement consisting of D681 to D684; this switch is used to select pairs of SAW filters on either the 806 to 825MHz band with Z681 and Z683, or the 85 1 to 870MHz band with Z682 and Z684. The diode switch is controlled by transistors Q681 an d Q 68 2.

The carrier signal level at the output of the SAW filters is approximately –7dBm. This signal is then further amplified in subsequent broadband stages Q691 to approximately +2dBm, Q501 to +15dBm, Q521 to +17dBm and Q531a to +20dBm. Each of these stages has a resistive attenuator network to provide isolation fr om the affects of transient load impedan ce changes. The output of final driver (Q531a) is fed through a resistiv e network consisting of R536, R537 and R538, to the input of the broadband power amplifier module (U561) at a level of approximately +16dBm.

The PA module (U561) contains three MOSFET stages to achieve the required maximum RF output power level of +44.4dBm (27.5 watts).

Care should be taken dur ing ser vicing, sinc e if for an y reason the drive power is lost while the power control

Note:

voltage is high, the current into the PA may exceed its specification. Therefore the power supply current limit should be monitored at all times and preset to as low as required. The radio has some additional inbuilt safeguards, but these should not be relied on.

Final power output settings are derived from alignment data stored in flash memory during the initial factory alignment. The DSP processes these data to optimise the power output level relative to the selected programmed channel frequencies.

PA current is monitored via comparator U551B, the output of which is passed via a temperature compensation network R552, R553 and NTC R554 , to the ADC, U301C. U301C s amples the applied voltage and then passes it to the PLA, after which it is pro cess ed b y the D SP. The PA c urre nt limit value is calibr ated as pa rt of the align ment procedure.

SRM9000X8 800MHz SERVICE MANUAL

3.2.2

The final output power is stabilised by a power control feedback loop. A printed circuit transmission line, L561, resistor R560, diodes D5 61A a nd D 561B, an d oth er as soci ated co mpon ents , form th e powe r detect or. Co mpar ator U551A and associated components provide the power setting and power control functions. Forward and reverse power is sampled by th e power detector a nd applied as a DC voltage to the inverting in put of the compar ator. The TX_PWR set voltage is a DC voltage proportio nal to the programmed Tx power setting and is applied to the noninverting input of the comparator.

The TX_PWR calibration voltage origin ates from the PLA as a PWM signal and is integrated for applicatio n to the comparator.

The PA module output level variation due to variations of supply voltage, output load or temperature, is detected and applied to the compar ator. The comparator proportionally adjusts the PA module bias supply and the bias supply for the PA driver (Q531A) and thus the PA drive level. High temperature protection is provided by thermistor R557, that progressively reduces the power level if the PA module temperature becomes excessive.

3.2.3

The antenna changeover c ircuit consisting of pin diode s D581, D582 and D583, is s witched by transistors Q571, Q572 and Q573 and associated circuitry, allowing the transmitter output to be coupled to the antenna while providing isolation for the receiv er input. With the transmitter switched on, the diodes are forward biased allowing power to be coupled through to the antenna and isolating the receiver by grounding its inpu t at C585. The short circuit at the receiver input is transformed to an effective open circuit at D581, by a lumped transmission line (L591), which minimises transmitter loading. With the transmitter switched off, the diodes are reverse biased allowing the receiver input signal to reach the receiver front end with minimal loss. The harmonic reject, low pass filter comprises L592, L593, L594 and associated capacitors.

Transmitter Audio Processing

The microphone audio input signal is applied to the radio microphone input (AUDIO_IN1) and is derived from an external microphone and pre-amplifier that provides a typical speech signal level of 40mV RMS. U801A is a control gate that switches between AUDIO_ IN 1 an d O P TION_AUDIO1 to provide external audio options and data inp ut.

U801C provides CODEC input switching which selects either the receiver “I” signal or transmitter audio/data signals depending on the Tx/Rx mode. All pre-emphasis, filtering, compression and limiting processes for narrow and wideband operation, are carried out in the DSP after A-D conversion by CODEC (U800). The processed transmitter audio/data from the CODEC o utput at VOUTR, is applied to the VCO as a modulation signal with a level of approximately 200mV P/P via AF Switch (U801B).

3.3 FREQUENCY SYNTHESISER

3.3.1

Refer to Figure 3-3. The frequency synthesiser consists of the RX VCO, the second local oscillator VCO (90MHz), loop filters, varactor

positive bias generator, reference oscillator, external divider and an integrated fractional N phase locked loop IC (U721).

3.3.2

The PLL is a high performance delta-sigma fractional-N device with an auxiliary integer-N PLL (U721). The PLL contains two prescalers, programmable dividers and phase comparators, to provide a main and an

auxiliary PLL. The main PLL of U721 controls the frequency of the RX VCO via CPRF at pin 1 and VCO feedback to FINRF at pin 4. The auxiliary PLL is use d to contro l the rec eiver 9 0MHz s econd LO VC O via C PIF at pin 16 a nd VCO feedback to FINIF at pin 13. The PLL operation involves the external frequency divider (U760) dividing the

15.36MHz reference oscillator by 32 to produce a PLL input reference of 480kHz; this reference is used directly by the RF PLL phase detector. The RX VCO frequency is sa mpled and divided down and compared to the refe rence frequency. Any error pr oduces an offset to the control voltage o utput that is used to c orrect the VCO freque ncy. A valid lock detect output is derived from LD pin 12 and is sampled by the PLA. During transmit, if an unlocked signal is detected, the radio will switch back to receive mode. An unlock ed signal in receive mode will cause the radio to beep.

For the IF PLL, the input reference is divided by 4 to produce a 120kHz phase comparator reference, which is a sub-multiple of the 90MHz second LO VCO.

3.3.3

The main RX VCO uses a low noise bipolar transistor (Q623) and associated parts to generate signal frequencies from 896MHz to 960MHz . Electronic tuning is provided by varactor diode (D610) with its c ontrol voltage derived from the Loop Filter, PLL and +16 volt Bias Generator. VCO buffer (Q631 and Q632) isolates the VCO from any load variations from its following circuits. The active power supply filter (Q622) minimises any supply related noise. A PLL feedback signal is returned from the VCO buffer output via amplifier Q640.

The 90MHz receiver second LO VCO comprises Q730 and associated parts. Automatic tuning is achieved by applying a control voltage to D73 0 an d D731, via Loop Filter R718, R719, R720, C732, C733 and C734.

General

PLL

VCOs

3.3.4

A positive bias voltage for varactor D610, has been used to achieve the required broadband tuning range of the VCO. PLL device, U721, is programmed to deliver a nominal +1.65V output from phase detector/charge pump CPRF, for any channel frequency selected. The CPRF voltage is filtered by the Loop Filter comprising C605, C607, C607a, C609a, R609 and R612; the loop filter removes any synthesiser noise or reference products. The resulting low noise c ontrol voltage is applied to the anode side of VCO var actor. The cathode voltage o f D610 is controlled by the output of voltage level translator Q780, Q781, Q782 and Q783. The level translator supply voltage is +16V, which is provided by U904E/F. The leve l translator output voltage is accurately c ontrolled by the PLA/DSP from values stored during VCO alignment. This voltage is varied versus frequency to maintain a typical CPRF value of +1.65V.

3.3.5

The modulation path for audio, data and higher frequency CTCSS signals is via varactor D610 and associated components. The reference input to the PLL (REFIN) provides the low frequency modulation path via a phase modulator.

The phase modulator comprises the following sections:

- Integrator U761A is a low p ass filter pr oviding 6dB per octave attenuation to frequencies above approximately

- Divider U760 divides the 15.36MHz reference frequency down to 480kHz.

- Ramp generator Q771 and Q772 provides a sawtooth output, the slope of which is adjustable

via the MOD_BAL line. This adjustment is set via a D AC output controlled from the Alignment Tool. Adjustment of the ramp slope effectively changes the Phase Modulator gain by modification of the Schmitt Trigger switching points after modulation from the Integrator is combined to the sawtooth ramp.

SRM9000X8 800MHz SERVICE MANUAL

The divided reference s ignal is differentiated and discha rges C778 via Q771, after which Q771 is turned off allowing C778 to recharge via constant current source Q772. The Schmitt Trigger comprising Q774, Q775 and Q776, converts the modulation combined with the sawtooth ramp, to a square wave output, th e d uty cycle of which is controlled by the ramp slope and modulation.

The Modulation Balance adjus tment is carried out usin g a CODEC-generated 100 Hz square wave applied to the TX_MOD input and set to give an optimum demodulated square wave output.

Reference Oscillators

3.3.6

Two TCXOs are used as optional reference freq ue ncies for carrier frequency generation and also to provide the DSP clock. U711 is the principal TCXO and oper ates at 15.36MHz and U712 is the alternate TCXO and operates at approximately 15.359767MHz. The alternate TCXO (U712) is frequency shifted to avoid specific receiver interference products. U711 and U712 are sele cte d by the REF_SHIFT line, which controls the complementary switch (Q711 and Q712). The outputs of U711 and U712 are connected to the PLL reference divider (U760) and to the input of U701, a high frequency PLL, the output of which provides the DSP clock signal.

The carrier frequency adjustments for U711 and U712 are achieved by setting the ADJ voltage by using the Alignment Tool. In addition, the ADJ in put is used in a frequency control loop with the re ceiver I and Q signals, to provide receiver AFC. The TCXOs are specified at ±1.5ppm frequency stability over the temperature range -30° to +75°C.

3.4.1

The SRM9000 transceiver operates und er the co ntrol of a DSP (U201 ) and PLA (U300) combinatio n that, together with a number of other dedicated de vices, perform all the operational and processing functions re quired by the radio. The PLA is configured by the DSP under software control to provide the following functions:

• Interface functio na lit y with Option Boards and External Devices

• Battery voltage and Tx current monitor

3.4.2

The PLA must supply several analog signals to control radio tuning. It does this with several Pulse Width Modulated (PWM) outputs.

The front-end tune signals (TUN E1 and TUNE2) originate from the PL A in the form of PWM signals. The values for these signals are stored in flash memory from radio alignment and are selected depending on the channel that the radio is currently tuned to. The PWM signals are integrated by RC networks to provide the analog tuning voltages for the varicap tuning diodes.

Other analog PWM derived signals used are transmitter power (TX_PWR), PLL varicap bias (VCAP_ADJ), receiver IF gain (IF_GAIN), Automatic Fr equency Control (AFC), AFC Switched (AFC_SW), VCO automatic level control (VCO_ALC) and modulation balance (MOD_BAL).

Analog inputs are monitored by four comparators comprising U301A-D and a ramp generator, the ramp being derived from a PWM signal from the PLA.

PLA PWM

SRM9000X8 800MHz SERVICE MANUAL

Analog voltages to be monitored such as PLL Loop Voltage (LOOP_VOLTS), battery voltage (BAT_SENSE), transmitter current (CURRENT_SENSE) and external sense (EXT_SENSE) are connected to the inverting inputs. The analog voltages are compared with the ramp voltage as they increase, and the comparator switches at the point where the input voltage exc eeds the ramp. The PL A compares the time at which th is occurs with the PWM signal and converts it to a binary value.

3.5 MEMORY

Memory consists of the internal DSP memory and an external 8MB non-volatile Flash Memory (U202). When power is off, all program SW and data are retained in Flas h Memory. At powe r-on, a boot pro gram download s the DSP and PLA SW from Flash Memory to their internal RAMs for faster program execution and access to data. PLA SW is loaded by the factory into the Flash Memory and can be updated via the Alignment Tool. DSP SW comprises Start-up code that is also loaded by the factory. High-level software comprising Operational Code and Customer Configuration are loaded at distribution centres and are loaded via the FPP Programmer.

3.6 POWER SUPPLIES

3.6.1

The unregulated 13.8V DC input (13V8_UNSW_F) is routed directly to all high current devices and is then switched via FET (Q900 ) to provide BAT_SW supply for all other circuits. The output fr om Q900 feeds three low dropout series regulators and switched battery voltage. These regulated supplies power auxiliary supplies as well as the negative and positive voltage gener ators. The radio ON/OFF func tion is achieved thr ough Q902, Q908 and Q909. A low voltage pulse from the control u nit or microphone handset PWR ON or PWR OFF momentarily turns on Q900/Q908 for approximately 1 sec . In th is time, th e radio DSP samples the PWR_SENSE line and determines the state of the on-off switch. If the on-off switch is on, the DSP raises the PWR_OFF line and latches the main FET (Q900) on, which then maintains power to the ra dio circuitry.

The Power-off operation r equires the On-Off switch to be turned off for more than 2 seconds. If th e On-Off switch is sensed going low by the DSP via the PWR_SENSE line, the DSP will save radio settings and then lower the PWR_OFF line, thereby turning Q900 off.

4. ALIGNMENT (LEVEL 3 SERVICE ONLY)

4.1 GENERAL

Preparing the radio for alignment will erase from the radio all customer PMR and Trunking

configuration data (channel, signalling information etc). The only data retained by the Alignment

Tool is the factory alignment data for the radio (DAC settings for Tx power, front-end tuning, etc).

Using the Alignment Tool will allow changes to the original factory alignment and will invalidate

If the radio contains customer configuration data that must be retained, you Personality Programmer (FPP) software to read all radio configuration files and save them on to alternative media

before

When the Alignment is completed, use the FPP software to retrieve the stored data and write it back to the radio. It is preferred that the radio remain in st alled in its aluminium extruded case throughout this alignment procedure. If

the radio is to be aligned when remove d f rom the case, a temporary heat sink must be fitted under the Transmitter PA module and the receiver output must be kept below 100mW.

Note. Final Tx power adjustments must be pe rf ormed with the radio board installed in the chassis.

Each transceiver will need to be individually tested and to have the resultant calibration data stored within it. This data cannot be modified by the user or by the normal customisation (eg. channel frequency, selcall ID etc.) process. It is set during the manufacturin g process and may be modified for maintenance purposes by use of the Alignment Tool. For customer channels between each pair of test frequencies, an interpolation is automatically carried out to determine the correct DAC values at the relevant frequency for the above calibration parameters.

commencing the alignment procedure.

Caution

must first

use the SRM/SRP

For all of the following alignment procedures it is assumed that the radio is connected to a Comms. Analyser or equivalent collection of test e qu i pment. The alignment is performed at room temperature, with a 50Ω termination on the antenna connector and with a po wer supply set to give 13.2V at the radio connector.

Warning

The RF power output from the transmitter during these tests can cause burns and can be dangerous to some discrete items of test equipment, hence power attenuators may be needed. Also the heat generated inside the radio after a long period of transmission can be hazardous.

SRM9000X8 800MHz SERVICE MANUAL

Calibration sequence

On a set that has not previously been calibrated or in which the calibration has been corrupted, preset parameters should be initially loaded into the radio for optimum alignment, after which the calibration steps must be carri ed out in the following order. These preset parameters may be obtained by reading a previously aligned radio or by loading predetermined default values.

A number of aspects of the radio need to have calibration data determined and stored during manufacture and subsequently used by the S/W during normal operation. These must be aligned in the following order:

• Tx and Rx VCO

• TCXO’s

• Tx power

• VCO ALC

• Tx modulation (deviation and then mod balance)

• Rx and Tx filter tuning

• Rx mute

• RSSI

• Tx Current Limit

ALIGNMENT PROCEDURE

VCO DAC Alignment

The frequencies generated by the Tx a nd Rx VCO’s are determined by the synthesiser loop output for fine control and by a DAC setting for coarse control. The DAC needs calibrating at each of four test frequencies. No calibration is necessary for the receiver 2nd LO.

During this procedure, the alignment program puts the radio into a special mode in which it ignores the ‘out of lock’ signal from the synthesiser.

Tx Power DAC Alignment

The transmitter output power can be programmed to three power ranges: 1W, 5W and 27.5W by the appropriate setting.

Note 1: Care should be taken not to set th e output power and hence supply current to excessive levels, ie. above 30W or 7.5A, since the higher heat dissipation involved may effect component reliability.

Note 2: Also, the antenna connector should be terminated directly into the Comms. Analyser for this test to minimise VSWR effects that could affect settings.

Note 2: Repeat the following steps as quickly as possible to avoid excessive heating the radio, which may affect calibration.

Note 3: The Tx Current Limit setting prov id es a maximum current limit into the RF PA module to protect it in the event of high dissipation as a result of inadequate drive power being applied relative to the Power DAC setting or high VSWR’s

SRM9000X8 800MHz SERVICE MANUAL

APPENDIX A - GLOSSARY OF TERMS

A summary of common radio terms and some other terms used in this document, and their meanings, are given below.

ADC AFC AGC Alarm

ANI Auto Interrogate Automatic Power

Automatic Volume

Busy

Analog to Digital Converter. Automatic Frequency Control. Automatic Gain Control. A Selcall sequence sent from subscriber equipment to indicate an Emergency situation. When activated the radio will enter a repeating sequence consisting of an Alarm Live

Transmit Time and an Alarm Dead Receive Time. Certain special conditions for the radio may also occur during the alarm. A dedicated SFM (trunked system) that is sent by pressing the Alarm Key. Automatic Number Identification. An Acknowledge identity sent as a response t o an in div idual reset call. Feature whereby the transmit power is automatically set to a level determined by the

level of the received signal. This is used to extend the battery life and/or reduce radiated emissions.

Feature whereby the background audio level is monitored and if this is found to be noisy then the volume level is increased to compensate, allowing the user to hear better.

The state of a channel such that:

• For a non-sign alling channel - if Busy this means that the carrier is above squelch.

• For a channel with CTCSS/DCS - if Busy this means a signal is being received with

either no CTCSS tone / DCS code or the correct CTCSS tone /DCS code.

• For a channel with Selcall - if Busy this means a closed channel where the signal is above squelch.

A feature that equates to 'Do Not Disturb' such that the radio will reject all non-

emergency calls. This feature can be activated using the Busy key (if assigned) or from a menu; it is reset to disabled at switch on.

C4FM Call Back

Channel Spacing Clipboard

Closed

CODEC

Compatible 4-Level Frequency Modulation. A request, sent by the dispatcher, to a unit requesting that the unit calls the dispatcher

back. The distance (in kHz) between the defi n ed frequency channels. A temporary storage area in Windows used t o st ore data in cut, copy and paste

operations. A state where transmit and receive are no t a llowed until a Selcall message to open the

channel has been received. A Closed Channe l is on e which defaults (when selected or after timed reset) to its closed state. Contrast with Open. Normally a Closed channel would have Selcall Mute and PTT Inhibit wou ld be enabled.

COde (Analog to Digital Converter) / DECode (Digital to Analog Converter).

SRM9000X8 800MHz SERVICE MANUAL

Community Repeater

CRU CTCSS

DAC Dash (-) digits DCS

A communications set-up whereby diff er ent groups of radios can operate by using only one base station. This is achieved by th e use of CTCSS tone signalling such that each group has a different CTCSS tone (en cod e and decode) and radios can only communicate with other radios in their group. Only one group of radios can use the base station at any one time.

Central Repair Unit CTCSS stands for Continuous Tone Controlled Signalling System. A continuous tone

(lower than the audio range of the receiver) is modulated onto the carrier as well as other signalling or voice traffic. Compare with DCS. Only receivers that have been instructed to recognise the same CTCSS tone are able to receive the transmissions, since the squelch of receivers looking for different CTCSS tones prevents the audio from being heard. This provides a simple method of sending messages to select e d re ceiv e rs on ly and allows several different networks to use the same frequencies. CTCSS is also known as Tone Lock or Tone Squelch.

Digital to Analog Converter. Digits known as 'No Tone' digits used in Selcall Id en tities. Digital Coded Squelch system is based on sendin g a continuous stream of binary code

words using, low deviation, direct frequ ency shift keying. Only receivers that have been instructed to recognise the same DCS sequence are able to open their squelch and receive the associated speech transmissions. This provides a sim ple met ho d of se nd ing messages to selected receivers only and allow s sev eral different networks to use the same frequencies.

Decode

Disabled

DSP DTMF

Dual Watch

Economiser

Enabled

Encode

External Alert

Reception of signalling. Either Selcall where encoded tone frequencies are decoded and identified as specific tones digits or CTCS S/DCS where tones are analysed to see if the channel should be opened.

The 'False' state of a parameter. That indicates this parameter is not active. Typically this state is represented by an unmarked check box. Compare with Enabled.

Digital Signal Processor. Abbreviation of Dual Tone Multi-Frequency signalling. Used to dial into Telephone

networks using tone dialling. A facility that enables the Radio to perio dica lly monitor another channel for a signal

above squelch. Typically applications a re ch eckin g an emergency channel whilst on another channel.

A process by which the Receiver is powered down whilst there is no received signal. Periodically the receiver is powered up to check for such a signal. This is used to extend the battery life.

The 'True' state of a parameter. That indicates this paramete r is active. Typically this state is represented by a mark (either a tick or a cross) in a check box. Compare with Disabled.

Transmission of signalling. Either Selcall where Selcall tone digits are encoded into tone frequencies or CTCSS/DCS where tones modulated onto the channel's carrier.

A facility for switching on various ancillary device s to mee t cu sto m er's ind iv i du al requirements (e.g. car horn, flashing lamp etc.) when 'called'. Only available on a mobile radio. To make available: go to Hardware Components, Terminal Settings and set Product Type to a Mobile type.

Fallback

A mode of operation that may be ente re d when the Network is suffering a malfunction. During this mode certain facilities (e.g. PSTN) may not be available.

SRM9000X8 800MHz SERVICE MANUAL

FFSK

Fleet

PLA FPP Hash (#) digits

Identity

Idle State Inaccessible

Link Establishment

which allows for the finite delay of the radio equipment in responding to an y radio signal.

Time

Fast Frequency Shift Keying. This is a signalling system for the transfer of digital information. It works by using one of two audio tones to represent transmit data..

A group of units formed such that only a shortened form of dialling (2 or 3 digits) is required between them. These groups are normally assigned contiguous ident's.

Programmable Logic Array. Field Personality Programmer. These digits are used for two purposes:

• For Selcall identities (encode and decod e) - known as User Id digits. These digits are replaced by the user id entered at switch on (if enabled)

Use in DTMF dialled strings - their use is network dependent to access special services.

•

Name given to a sequence of tones which is used in sequential tone signalling. See Valid Selcall Digits.

The state of the radio when it is not in a call . A state of a channel such that it is unavailable to the user through normal methods of

channel selection. Therefore inaccessible channels will not appear on the channel menu. A delay incorporated into the start of every selective call or DTMF transmission

This includes both the commencement time of the originating transmitter and the response time of the receiver.

Locked

Null Id Open

PABX Password

PLL PMR Priority Channel PSD PSTN PTT

A state of a channel whereby it is not possible to change channels using the normal up/down keys on the channel menu until th e O K key is pressed. See Auto Channel Selection Lock.

A Selcall identity that is not defined and whose tones' field is displayed as a blank. A state where transmit and receive are allo we d. The channel is no longer open when

reset. Contrast with Closed. Normally an Open channel would not have Selcall Mute and PTT Inhibit would be

disabled. Private Automatic Branch Exchan ge .

An optional password system available on the radio. This feature is only available if the radio has a display and a keypad. To make available: go to Hardware Components, Terminal Settings and set Product Type to one which has a display and a keypad.

Phased Locked Loop. Private Mobile Radio (not normally trunke d). A channel in a search group that is scanned be tween every other channel. Peak System Deviation. Public Switched Telephone Network. Press To Talk. This is the term given to the operator’s key normally used to commence

transmitting a message.

PTT Inhibit PWM

A state whereby transmission using the PTT is no t allowed. Also know as Tx Lockout. Pulse Width Modulation.

SRM9000X8 800MHz SERVICE MANUAL

Reference Frequency

Repeat Tone

Reset

RSSI Scanning

Normally this is generated from a high stability crystal oscillator reference and is divided digitally in a frequency synthesiser for comparison with other frequency sources, e.g. a VCO.

A selcall tone that is used to replace repeated tones. Fixed at tone E. Example: An identity entered as '12333' would be sent by the radio as '123E3'. Resetting is caused by Three Tone Reset, a Remo te Reset, an Individual reset or a

Group reset (Call Types in Decode Identity). When a radio is reset the effect on the radio will be as follows:

• Any Call Alerts will be stopped

• The Call LED flashing will stop

If the channel is in Open mode then the channel is closed

•

• The PTT is optionally inhibited see PTT Inhibit After Reset Sequence.

• In searching - if paused on a selcall channel then searching resumes

• If the Acknowledge property of a Decode Identity is set to 'Auto Interrogate' or

'Transpond & Auto Interrogate' then the Auto Interrogate encode identity is transmitted. Received Signal Strength Indicator.

Process of switching between the channels in t he nominated search group in cyclic sequence, stopping when the search condit ion (which may be to look for either a free or a busy channel) is satisfied.

Search Group

Selcall

Selcall Mute Selcall System

Sidetone

Squelch

Star (*) digits

Status

A group of channels that are either scanned for a signal above the search threshold or are compared and voted for the stro ngest signal

Selective Calling - a system of signalling which allows 'dialling up' of specific mobiles, portables and controllers. Such a syst em ma y be used to pass messages as a data message to a specific user or group of users. It can be used to provide remote switching facilities and to provide access control into community repeaters or similar devices.

A state of the audio gate whereby the loudspeaker is muted (closed). Sel

ective Calling, uses a tone sequence at the start, and end , of a call to control which

members of a fleet react to the transmission. Sidetone is the audio which can be (optio na lly ) heard when Selcall, DTMF and toneburst

transmissions are made. Mode of operation whereby the radio operates as a conventional fixed channel radio

outside the Trunking network. System used to prevent weak, unintelligible signals and random noise from being heard

by a radio operator while still allowing int elli gib l e sig na ls to be received normally. This is accomplished by the use of a threshold below which any received signals are ignored. Only signals whose signal-to-noise ra tio is above the squelch level cause the audio circuits of the radio to be enabled, with the result tha t only s atisfactory signals are received. The squelch level is specified in SINAD.

Digits known as Status or Message digits. These digits are used for three purposes:

• Status Digits for Selcall Identities

• Wildcard digits in Status strings

• Use in DTMF dialled strings - their use is network dependen t to access spe cial services.

A feature whereby a radio's status (or usually the status of the radio's user) can be transmitted and a status message from other radios can be displayed. This operates

SRM9000X8 800MHz SERVICE MANUAL

through status digits in Selcall ident ities. Either in Encode Identities or Decode Identities as follows:

Encode Identities: Status digits within the identity are used to transmit the current situation of the radio's user (e.g. "Out To Lunch").

Decode Identities: Status digi ts are looked up in a table (Status Menu) for possible messages to display.

SW TCXO Three Tone Reset

Tone Burst

Transpond Tx Inhibit

User Identity

VCO Vote
