1 Oper ating Instr uctions

1.1 Fr ont Panel Contr ols and Indicator s

1.1.1 Monitor Volume

The Mon. Volume control is used to adjust the volume of the internal loudspeaker and any external speaker connected to the test socket. It does not effect the level of the 600 Ohm line output level, nor the direct audio output level.

1.1.2 Monitor Squelch

The MON. SQ. switch allows the normal squelch functions controlling the monitor output to be disabled. When the switch is in the MON. SQ. position the audio at the monitor speaker is controlled by the noise detector. The CTCSS, carrier, tone, DCS, and external squelch functions will not stop the audio from being broadcast by the speaker. This can be useful when you are trying to trace the source of on channel interference or when setting the noise squelch threshold.

The audio from the 600 Ohm line output, and the direct audio output, is not effected by the switch position.

1.1.3 N.SQ

The N.SQ trimpot is used to set the noise squelch sensitivity. Use the following procedure to set the noise squelch to maximum sensitivity.

(a) Set the toggle switch to the MON.SQ. position and set the MON VOLUME control to 9 o'clock.

(b) Turn the N.SQ. adjustment counter clockwise until the squelch opens and noise is heard from the speaker. Adjust the VOLUME to a comfortable listening level.

(c) In the absence of any on channel signal, Turn the N.SQ. screw clockwise until the until the noise in the speaker is muted.


1 OPERATING INSTRUCTIONS

1.1.4 C.SQ

The C.SQ trimpot is used to set the carrier squelch sensitivity. Carrier squelch is useful at higher signal levels than noise squelch and can be used from 1 - 200 uV input.

It is provided mainly for use in fixed link applications where a high minimum signal to noise ratio is required or where very fast squelch operation is required for data transmission. The carrier squelch will open and close in less than 2 mSec.

In most base station applications carrier squelch is disabled by turning the adjustment counter clockwise until the screw clicks.

The carrier squelch may be set to a predetermined level with the WinTekHelp software or by using the following procedure:

(a) First turn the adjustment fully counter-clockwise. Then set the noise squelch as above.

(b) Connect a source of an on channel signal with the desired threshold level to the receiver's RF input.

(c) Turn the screw clockwise until the SQ LED goes OFF. Then turn the screw back until the LED just comes ON.

1.1.5 LINE

The LINE trimpot is used to set the line and direct audio output levels. It is normally set to output 0dBm on the Line output when the carrier is modulated with a

1kHz audio signal at 60% of maximum deviation. NB that 0dBm is equivalent to 774 mV to an open circuit, or 387mV into a 600 ohm load.

1.2 Fr ont Panel Indicator s

1.2.1 PWR LED

The PWR LED shows that the dc supply is connected to the receiver and that the microprocessor is not being held in a RESET state.

1.2.2 SQ LED

The SQ LED comes on when the audio to the line and direct outputs is un-squelched.

The LED and squelch function are controlled by the external squelch input, and/or the noise, carrier, tone, or DCS squelch circuits.

1.2.3 ALARM LED

The ALARM LED can indicate several fault conditions if they are detected by the self test program. The alarm indicator shows the highest priority fault present.

See Table 1.

2 Receiver Options

There are many software selectable options. Some options are selected on a per channel basis, and some are defined globally (i.e. the parameter is fixed irrespective of which channel is selected). Below is a description of these global parameters

2.1 Ser ial I/O Par ameter s

There are two serial ports. There is the main serial port which is brought out to the front panel connector. This is referred to as PORT0. There is another serial port which is for factory use only. It is referred to as PORT1.

The baud rate, can be defined for PORT0. PORT0 is set by default to 57.6Kbps, with

No parity.

2.2 Receiver Low Batter y Level

This is factory set to 24.0V, and defines the level of the DC supply that will cause a

Receiver dc supply low alarm.

2.3 LOOP Volts Select

By default, when the squelch opens and the Line output audio is enabled, 12V is applied to the Line+/Line- pair through 680 ohms. The 12V power source is removed when the squelch closes.

In Rev. 2 receivers, the user can select to reverse the application of 12V, ie 12V is applied when the squelch is closed, and removed when the squelch opens.

In Rev. 3 (or later) receivers, the user can select to apply a DC loop to the Line+/Linepair instead of applying 12V. Similarly, they can select to reverse the application of the Loop, or the voltage, depending on the squelch state.

2.4 COS Sour ce/Sink Select

The COS output can have four possible states: a) 12V: 12V is applied to COS+/COS- through 680 ohms, b) 0V: ie COS+ is shorted to COS- which is shorted to GND, c) shorted: COS+ and COS- are shorted together, but both are electrically isolated, d) open: COS+ and COS- are not shorted together, but both are electrically isolated

In states (a) and (b), the receiver applies either 12V to the COS+ pin, or GND. The

COS- pin is connected to GND in both states. The receiver acts as a “source” when in either of these two states.


In states (c) and (d), the COS+/COS- pair can “sink” current, or not sink current, that is sourced elsewhere.

The receivers will either toggle between states (a) and (b), or toggle between states (c) and (d), depending on the state of the squelch.

The user can select which of these two modes they wish to use.

The default COS mode is to toggle between states (a) and (b)

2.5 COS Polar ity

By default, +12V is applied to COS+ when the squelch opens, and COS- is connected to ground, ie the COS+/COS- pair are placed into state (a) when the squelch opens, and are in state (b) when it is closed. (see 2.4 above).

The user can optionally select to reverse this.

Similarly, if , the user has chosen to operate COS as a “sink” (see 2.4 above), the default is to short COS+ to COS- when the squelch opens (state (c) above), or open them when the squelch closes. The user can reverse this as well.

2.6 Noise Blanker

The R50 has a noise blanker. This circuit detects RF impulses and quenches the RF before it is de-modulated. This prevents “clicks” and “pops” from being detected and passed through to the audio. The noise blanker can be enabled or disabled by the user.

2.7 Advanced Slot Selectable Par ameter s

WinTekHelp receivers have several advanced features. These features can be programmed for each channel.

One of these advanced features is to program up to 8 frequencies on a channel. When this is done, we refer to the “channel” as a “slot” to avoid confusion, as many people equate the word “channel” with the word “frequency”.

When more than one frequency is assigned to a “slot”, and that slot has been selected from the channel input, the receiver will automatically scan all the assigned frequencies, tuning to the first that has sufficient carrier strength and/or

SINAD, and a correct CTCSS tone, or correct DCS code.

In this “scanning” mode, one of the frequencies can be given “priority”. If this is done, the receiver will check, every few seconds, if there is a signal on the priority frequency, and if so, it will switch to the priority frequency. It will stay tuned to the priority signal, whilst signal is present on it, but it will then resume its usual scanning function, if the signal is lost.

Another advanced feature is the ability to assign more than one CTCSS tone to a frequency. When this is enabled, the receiver checks if the received CTCSS tone is one of up to 6 tones rather than just one.

Another advanced feature is to inhibit the assertion of COS, or loop, (or both) when the squelch opens depending on either the frequency received or the tone detected.

For example, in a scanning situation, with two possible frequencies, LOOP can be programmed to be asserted if one frequency is detected, or COS to be asserted


if the other frequency is detected. Similarly, one can enable/disable the default assertion of COS and/or loop depending on which CTCSS tone is detected.

Other advanced features are: a) de-emphasis: enabled or disabled, depending on frequency b) start and end delays for COS and LOOP.

c) scanning interval for the priority frequency, d) increments or decrements in the carrier level or noise level thresholds, depending on the frequency. For example one frequency can be set to have a higher noise threshold than another. Units are in dB of carrier signal, or

SINAD dB.

2.8 Standar d Channel Par ameter s

Each channel can set the following standard parameters: a) frequency, b) one CTCSS tone, or DCS code.

4 Channel Progr amming and Option Selections

Channel and tone frequency programming are most easily accomplished with RF

Technology WinTekHelp software. This software can be run on an IBM compatible PC and can be used to calibrate a T50, R50, and PA50 as well as


program channel information. See the WinTekHelp users manual for further information.

5 Cir cuit Descr iption

The following descriptions should be read as an aid to understanding the block and schematic diagrams given in the appendix of this manual.

There are 7 sheets in the schematic in all.

5.1 R50 Master Schematic (Sheet 1)

Sheet 1, referred to as the "R50 Master Schematic", is a top level sheet, showing four circuit blocks, and their interconnection with each other, as well as the interconnection with all connectors and external switches.

P1 is the front panel DB9 RS-232 connector for attachment to a terminal, a terminal emulator, or to an IBM PC running the WinTekHelp software.

P3 represents the rear female DB25 connector.

J1 is the terminal on print circuit board, it is connected to the internal load speaker.

JP2 is for the attachment of an LCD display module. This has been included for later development.

JP3 is a specialised connector for test and factory configuration use only.

D102, D103, and D104 represent the three front panel LEDs.

5.2 Micr opr ocessor (Sheet 2)

Sheet 2 describes the basic microprocessor circuitry.

The core CPU is the Motorola XC68HC12A0. It is configured in 8 bit data width mode.

The CPU is clocked by a 14.7456MHz crystal oscillator circuit (top left) comprising the JFET Q202, and two switching transistors Q203 and Q204.

The CPU contains an 8 channel A/D converter whose inputs are identified as AN0,

AN1, …, AN7.

AN7 is used as LOCK detect inputs from the Locked Loop (PLL) circuits (see 5.6)

AN6 is used to sense the noise squelch level setting.

AN5 is used to sense whether or not the dc supply is within spec or not.

AN4 is used to sense the audio from the discriminator, so the R50 receiver can be used as a deviation meter.

AN3 and AN1 are inputs from the PLL circuits that sense the bias voltage on the VCO control varactor for each VCO.

AN2 is used to sense the carrier squelch level setting.

AN0 is used to sense the RF input signal strength which is detected by the IF chip.

FRDY is an output from the flash. It goes low when the Flash starts to write a byte of data, or erase a block, or erase the whole chip, and it returns to its default high state when the action requested has completed.


FPSW1, FPSW2 and FPSW3 are three pins that have been reserved for future use as switch inputs.

LOOP/VOLTS_SEL is a CPU output that when high applies 12V of dc feed to the audio output.

LINE_LEVEL_U/D and LINE_LEVEL_INC are CPU outputs which are reserved for controlling a digital potentiometer in future.

COS_VOLTS_ON/OFF is a CPU output that when high applies 12VDC feed to

COS+ terminal, so that the COS can be selected as +12VDC source or a free switch.

COS_POLARITY is CPU output that when low turns Opto-coupled transistor switch

U601on. It is controlled by the noise squelch detect, carrier squelch, or external squelch signal

SQ is a CPU output that when low, enables the 600 ohm line output, and the direct audio output. It is controlled by the noise squelch detect, carrier squelch, or external squelch signal

N_BLK_EN is a CPU output that when low turns noise blanker option off.

CTCSS_SEL is a serial bus select pin. It is used to select the FX805 chip(U500), which is used to decode CTCSS tones. (see 5.5)

PLL_SEL is a serial bus select pin. It is used to select the PLL chip in the PLL circuit

(U302). (See 5.6)

RCV_ADSEL is a serial bus select pin. It selects the quad Digital to Analogue converter (DAC) that sets the levels for the 12MHz reference oscillator bias voltage, 21.855MHz oscillator bias voltage, noise squelch comparator bias voltage and the LCD bias circuit. (see 5.4)

CH_EN is a serial bus select. It is brought out to the rear panel and is used to interface to the channel encoder on the rear daughter-board. (See 5.1)

FLAT and DE_EMPHA are outputs which are the logical inverse of one another.

When the FLAT pin is low, the audio output is flat response, when

DE_EMPHA pin low, audio is 750uSec de-emphasized.

Fo_PLL is derived from the the Fo output of the PLL chip. It is Fo after being divided by 100. They should be 312.5Hz square waves, except for brief periods when frequencies are being changed. (See 5.6)

MON_SW is a digital input which represents the state of the front panel MON.SQ

switch.

LCD_DB7 is a signal that has been reserved for interfacing to an LCD display.

ECLK is a pin that at start-up only, should have the CPU system clock of 7.3728MHz

on it.

SQ_LED, ALARM_LED, are CPU outputs that drive (when low) the SQ LED, and the ALARM LED.

T/R_RELAY_H is a spare pin which is not used in the R50 receiver.

SCLK, and MOSI are used as the core of a serial bus. SCLK is a clock pin, and

MOSI is a bi-directional data pin.

DBGTX_TTL, DBGRX_TTL are RS232 transmit and receive (TTL) data pins which are connected to the debug port after conversion to/from RS232 compatible voltage levels by U202 and U201.


TXD_TTL, RXD_TTL, RTS_TTL, CTS_TTL, DTR_TTL, DSR_TTL, are RS232 data pins which are connected to the main front panel serial port, after conversion to/from RS232 compatible voltage levels by U202 and U201.

N_DET is used to sense the noise squelch output of the receiver section. (see)

SUBTONE_IRQ is connected to the interrupt pin of the FX805 (U500). When

CTCSS tones change state, ie a new tone is detected, or an existing tone stops being received, or 8 bits of NRZ data (when decoding DCS codes) are received, this signal is asserted to force the CPU to read data from U500.

INT is a dedicated CPU interrupt input pin. It is used to detect the state of the external squelch signal.

BKGD is a bi-directional I/O pin used to communicate with the core of the CPU. It is connected to the debug port and is utilised by specialised hardware to control the CPU externally, even without any firmware being present in the Flash.

The RESET pin is both a low active input and a low active output to the CPU. If generated externally to the CPU, it forces the CPU into reset, and if the CPU executes a RESET instruction this pin will be driven low by the CPU.

Whenever there is insufficient volts (< 4.65V) on pin 2 of the MC33064D (U203), it will keep its RES output low. After the voltage has met the right level it will assert its output low for another 200 milliseconds. Thus the CPU will be held in reset until VCC is at the correct level. Thus the PWR_OK LED will only light when VCC is within specification, and RESET has been released.

S200 is a momentary push-button switch that, when pressed, will cause the CPU to be reset.

MON_SQ is a CPU output which is used to enable (when low), or disable (when high) the audio at the monitor speaker.

LCD_RS, LCD_R/W, and LCD_E are reserved for interfacing to an LCD display module. Note that this feature has not been implemented.

U205 is used to select whether the Flash or RAM is to be read or written.

U207 is a single supply, 5V, TSOP40 Flash chip of size 8, 16, or 32 Megabits, and is used to store the firmware.

U208 is a 1, or 4, Megabit Static RAM in an SOP-32 package, and is used for both code and data. The code in the RAM is copied from the Flash, at start-up.

5.3 RF Section (Sheet 3)

Sheet 3 is a schematic of the RF section, which itself refers to two other subsheets.

U301 is a quad Digital to Analogue converter (DAC). OUTA (pin2) is used to adjust the 3rd local oscillator frequency. OUTB (pin1) is used to adjust the frequency of the 12MHz reference. OUTC(pin16) is used to set the noise squelch comparator offset voltage. OUTD (pin15) is reserved for future use.

Communication between U301 and the MicroController, U204, is via the serial bus.

U302 is a dual channel PLL chip, X301 is the reference for both PLL channels. PLL channel 1 is for the 1st VCO, and channel 2 is for the 2nd VCO. C315, C317,

C327, R316 and R317 are components of the loop filter for the 1st VCO,

C316, C328, C329, R330 and R331 are for the loop filter of the 2nd VCO.


U303A, U303D are buffers that isolate the bias voltage. The Microcontroller,

U204, has both of these buffered voltages connected to two of it’s A/D ports.

U304A, U304B divide the FoLD of the PLL chip by 100, and send it to a Timer input pin of the MicroController, U204.

5.4 Receiver Section (Sheet 4)

The RF input signal (25MHz-50MHz) is first filtered with a band-pass filter. This is implemented with two filters, firstly a high pass filter (C401, C402, C403,

C407, C415, C416, C417, C419, C420 and L401, L404, L405, L406) and then a low pass filter (C404, C405, C406, C421, C422 and L402, L403, L407,

L408).

After band-pass filtering, the signal is amplified. Q401 is the front-end amplifier.

After amplification, unwanted products generated by the amplifier are filtered.

The capacitors and coils between Q401 and C457 provide this additional filtering for the RF signal amplified by Q401.

This amplified RF input signal is referred to on the schematic as RF_AMP. It is upconverted by mixer MX401 to create the 1 st

IF. It is also amplified by Q405, and Q406, which are the front-end amplifiers for the Noise Blanker circuit.

The output of Q406 is “detected” by D401, and if the waveform “envelope” exceeds approximately 3.3V, the output of U403 will go high. U404 is a retriggerable monostable multivibrator, which produces a pulse at least 2usecs long after each rising edge detected on the output of U403. If rising edges re-occur during each pulse, the pulse period keeps extending until they stop.

The output of U404 is level shifted and inverted by Q408 to create the blanking signal

N_BLK. C470, R416, and R414, act to slew the negation of N_BLK, without affecting the slew rate of the assertion of N_BLK.

U303C provides some AGC for the RF amplifier formed by Q405 and Q406. They also reduce the intermodulation which is produced by Q405 and Q406.

MX401 is a double balanced mixer which converts the RF signal to the 1st IF. The frequency of the 1st IF is at least three times higher than the highest RF frequency to obtain good image and spurious rejection. In the R50 receiver, the

1st IF frequency is approximately 246MHz. The actual frequency depends on the frequency tuned to, and may vary by as much as +/- 120kHz. The 1 st

LO is set to be approximately 264MHz above the frequency being tuned to.

Q402 is used to amplify the 1st IF signal before it is filtered by FIL401.

FIL401 is a SAW filter, which provides an excellent spurious rejection for the 1st IF.

The filtered IF signal is then fed to double balanced mixer MX402. The output of

MX402 produces the 2nd IF, which is then amplified by Q403. The 2nd IF frequency is set at exactly 21.400MHz, to avoid interference from any in-band

RF signals. The 2 nd

LO is set to approximately 224.6MHz. Again the LO frequency may vary from 224.6MHz by as much as +/-120kHz depending on which frequency the receiver is tuned to.

Q404 and Q409 gate the 2 nd

IF signal. If the N_BLK signal is high, then the 2 nd

IF is quenched. N_BLK is generated by the impulse noise detector.

FIL404 and FIL405 are two 21.4MHz crystal filters. Combined they form a four pole crystal filter. The filter has a minimum of 40dB attenuation at the adjacent channel frequencies (25kHz channel spacing). C448, C477, L423 and


components between FIL405 and U401 form the matching network for the filter.

U401 is an IF receiver IC which includes mixer, oscillator, amplifiers and discriminator. It down-converts the 2 nd

IF to the 3 rd

IF at 455kHz, which is filtered by ceramic filters FIL402, and FIL403, before the signal is demodulated(discriminated). The discriminator uses ceramic resonator X401 as its 455kHz reference.

X402 is a crystal used to create a 21.855MHz oscillator that becomes the 3 rd

LO. The frequency can be varied slightly by varactor D406, and thus it can be adjusted by the 3rd_LO_ADJ voltage. This is done as part of calibration.

Pin9 of U401 is the recovered audio output. C411, C412, C413, R441, R444 and

U402A form a 5 th

order ellyptical high pass filter with 3dB cut-off at 7.5kHz.

Any “signal” at such frequencies is assumed to be noise, as exciters sharply attenuate all signals above 3kHz. U402B amplifies this FM “noise” signal, and

D403 and C438 act as a peak detector. The voltage on C438 is proportional to the square root of the noise energy. U402C works as a comparator which asserts the low active digital signal, N_DET, if the noise voltage is higher than the D/A output, NSQ_SET.

Pin8 of U401 is the other recovered audio output which can be muted by pin5.

Capacitor C484, and D407, ensure that the audio remains muted until the

+10V is at the right voltage. The discriminated audio signal is amplified by

U605A and then fed into the Audio Section (Sheet 6).

Pin7 of U401 is the Radio Signal Strength Indicator (RSSI) output. U402D is a buffer.

The RSSI voltage is converted to a digital value by one of the A/D inputs of the

MicroController.

5.5 Voltage Contr olled Oscillator (Sheet 5)

There are two similar VCO circuits in this sheet, the difference between these two

VCO is component values, so only one VCO circuit is illustrated in this section.

Q501, C532, C533, C534 and L501 form a Colpitts oscillator, the frequency of the oscillator is decided by the tuning voltage of varactor D501. The capacitance of D501 is in series with C531, and this total capacitance is in parallel with

C501 and also with the series connection of the feedback capacitors C533 and

C534. The net capacitance forms a tank resonance with the, high Q, air coil inductor, L501.

The bias for varactor D501 comes from the loop filter of the 1st PLL. Q503 forms a gyrator circuit which reduces noise that might be injected from the power supply.

The parameter, Vgs

(off)

, of Q501 can vary from 1 to 4V. D503, R517 and C519 provide some AGC, in order to reduce the dependence of the output level on this parameter.

MMIC amplifier MA501 provides about 20dB gain for the VCO signal and feeds it to the PLL chip.

MA502 and MA503 provide about 30dB gain of the VCO signal to drive the LO port of the double balanced mixer MX401 at a nominal level of +7dBm.

NB that Q506, R547, R531, L508, C510, C540, R537, and R536 are not fitted. Place for these components has been provided on the printed circuit board to allow


the possibility of replacing MX401 with a mixer that requires a higher level of

LO drive (but an improved IP3 figure).

5.6 Audio Pr ocessing Section (Sheet 6)

The discriminator output from the RF section is connected, in this audio section, to a peak detector formed by U604 and C623. This peak detector output is passed to an A/D input of the Microcontroller to be used as a simple deviation meter.

This raw detected audio is then attenuated by R642 and R655 before being filtered.

This attenuation is required to ensure that the audio signal will fit into the dynamic range limitation of the CTCSS chip, U602.

The raw, unfiltered Discriminator Audio signal is attenuated by R658 and R657 before being connected to the rear panel connector P3.

U605B, R642, R643, R644, C626, C627 and C628 form a 5 th

order ellyptical low pass filter with 3dB cut-off at 4.2kHz.

U602 is a CTCSS tone encoder and decoder. U602 can receive and transmit NRZ data, and as such can be used, with suitable firmware, to receive or detect DCS codes.

The CPU accesses U602 via the serial bus using MOSI, SCLK, and the low active

Select signal CTCSS_SEL. When U602 detects new CTCSS tones, or detects the absence of a tone, or receives bytes of NRZ data, it signals the

Microcontroller by asserting the low active signal SUBTONE_IRQ.

The 4MHz crystal, X401, is used as the reference for decoding CTCSS tones, or setting the bit rate for NRZ data. U602 has a built-in high pass filter, between pins 10 and 11, which can eliminate any subtone, or low frequency NRZ data.

Whilst the Microcontroller can enable or disable this filter, in the R50, it is always enabled. The subtone output from Pin17 is amplified by U605C. The output from U605C is ac-coupled to the rear panel connector P3, through capacitor C604.

The audio paths in U602 are all dc-biased to Vcc/2. The audio paths before and after

U602 are zero-biased.

U609B is set up as an inverting amplifier with a nominal gain of unity at 1kHz. If the signal FLAT, is asserted low, analogue switch U607A is enabled. This sets the gain at unity across the audio band. If, on the other hand, the digital signal

DE_EMPHA is asserted low, analogue switch U607B is enabled, and the gain becomes proportional to frequency. Thus de-emphasis is applied to compensate for any pre-emphasis applied at the exciter.

The audio is connected to the Line outputs and the DIR_AUD output, when the digital signal SQ is asserted low.

The audio is connected to the speaker amplifier when the digital signal MON_SQ is asserted low.

U609C is the amplifier for the 600 ohm line output. U609D is the amplifier for the direct audio output (DIR_AUD). The output level of the 600 ohm output is adjustable via VR601 on the front panel.

U604 is the power amplifier for internal and external speaker. The volume can be adjusted by VR602 on the front panel.

RL602 may apply, or remove, 12VDC to the 600 ohm line output. Whether this occurs or not, and whether the voltage is applied when the squelch opens or


closes depends on the way in which the channel is programmed by the user.

The position of RL602 is controlled by the signal LOOP/VOLTS_SEL from the MicroController.

Opto-coupled transistor switch U601 provides a COS (Carrier Operated Switch) output which is controlled by the digital COS_POLARITY signal from the

MicroController. The output COS+ and COS- can be used as +12V DC source or a free switch depending on the status of the relay RL601. RL601 is controlled by the digital COS_VOLTS_ON/OFF signal from the

MicroController.

5.7 Power Gener ation Section (Sheet 7)

U909 converts the +12V rail to +5V for all the digital circuitry.

The +12V rail is used to power the two on-board relays, as well as up to one extra offboard relay. It is also dropped, via a linear regulator (U910) to produce the

+10V rail, which in turn is dropped by another linear regulator U911 to produce +5Q, which, in turn, is dropped by a further linear regulator (U912) to produce +2.5V.

Similarly U913, U914, and U915 are linear regulators that produce –10V, -5V, and –

2.5V from the –12V output of U908.

+10, +5Q, and +2.5V, -10V, -5V, and –2.5V rails are used in the audio and RF sections.

D911 is a 4.096V (3%) reference diode. Its output is buffered by U906 which then produces a reference voltage rail Vref, which is used by the CPU’s A/D converter, and the DACs, and also in the voltage to current converters of the

VCAs (see Sheet 4, and Sheet 7).

There are three switch-mode dc-dc converters in the board. These use monolithic converters based on the National LM2595. Two of the converters are 12V converters and one is a 5V converter.

The power in to the whole exciter is the voltage rail 28V.

U907 converts this down to 12V.

U908 is set up as an inverter, and uses the 12V rail to create -12V.

U909 converts the +12V rail to +5V for all the digital circuitry.

The +12V rail is used to power the two on-board relays, as well as up to one extra offboard relay. It is also dropped, via a linear regulator (U910) to produce the

+10V rail, which in turn is dropped by another linear regulator U911 to produce +5Q.

Similarly U913 and U914 are linear regulators that produce -10V and -5V from the -

12V output of U908.

NB -2.5V is not used in the R50 receiver. In case, it is ever required in a future release of the R50, it has been included in the schematic. U915, though is not fitted to the printed circuit board.

D911 is a 4.096V (3%) reference diode. Its output is buffered by U906 which then produces a reference voltage rail Vref, which is used by the CPU's A/D converter, and the DACs.


6 Field Alignment (Calibr ation) Pr ocedur e

6.1 Standar d Test Equipment

Some, or all of the following equipment will be required:

•

Power supply set to 28Vdc, with current >0.25A.

•

RF Signal Generator with 50 Ohm Output impedance, and Frequency range

25-50MHz. The signal generator must be capable of generating a carrier aith output level adjustable from –60dBm to –128dBm. It must be able to FM modulate the carrier with a 1kHz audio signal with deviations of 3 and 5kHz.

•

Frequency Counter, or spectrum analyser, capable of measuring frequency accurate to 0.5ppm.

•

True RMS AC voltmeter with bandwidth > 20kHz, and,

• a DC voltmeter.

6.2 Invoking the Calibr ation Pr ocedur e Manually

From Version 4 of the firmware, and version 1.4 of WinTekHelp, the calibration procedure can be performed through a Windows front end program. This is documented in the WinTekHelp manual. It is recommended that you use the new Windows based procedure for calibrating each R50.

The firmware still supports the older command prompt method, which is described in this section.

The firmware will requests the user for information as to meter readings, and/or to attach or adjust an AF signal generator.

The firmware based calibration program can be accessed from a terminal, a terminal emulator, or the WinTekHelp terminal emulator.

If the user selects the “Go to the Prompt Window” option from the main menu, they can manually type commands to invoke the calibration procedure. When the exciter is ready to accept commands it echoes the following prompt:

R50>

Via a terminal, or a terminal emulator, a user can type various commands in. The basic command to start the calibration procedure is:

R50> cal calibration_type

Where "calibration_type" is one of:

(a) misc: Miscellaneous parameters are defined and calibrated

(b) line: Line1, Line2, Dir Aud (Tone), and microphone inputs are tested and calibrated.

(c) ref:The reference oscillators are adjusted and calibrated

6.3 The " Miscellaneous" Calibr ation Pr ocedur e

R50> cal misc

This procedure should not normally be invoked as part of any field maintenance.

The program will print out the Model Name and Serial Number of the exciter. If these parameters haven't already been defined (e.g. at an initial calibration, at the factory, the service personnel will be prompted to enter these values).


Then it will ask the operator to enter the value of Vref (as measured at TP913, see

5.7).

Measure the voltage, at TP913 (Vref) and type it on the command line...

Unless the reference diode D911 has been replaced, this should not be done. The user should simply hit the Enter key to bypass this operation. If, though, D911 has been replaced for some reason, then, the lid of the unit should be removed, and the voltage measured. TP913 can be found just above JP12 (near the centre of the exciter).

Then the receiver low battery alarm level will be asked for. If the current value is acceptable, the User need only hit the Enter key on the keyboard. If another value is preferred, then that value can be typed in.

For example:

The Exciter's Low Battery Alarm is 24V

If this is correct enter < RET> ,

else enter the new value: 26

In this example, the low Battery Alarm level is changed to 26V.

Then the user will be prompted for serial port baud rates, etc. Please leave these parameters unchanged unless you are familiar with how to change such parameters on your PC. The WinTekHelp software will expect 57600 BPS, and No Parity. Note well, that if you do change any of these, the change will not take effect until you power down the receiver and then power it up again.

(As an alternative to power cycling the receiver, and if the cover is off the receiver, you may simply press switch momentary push-button S200 (see 5.2).

Then the following questions are:

Is Flat frequency response on by default (Y/N)?

Is COS purely a sink of current (Y/N)?

Is COS Asserted when the Squelch is closed (Y/N)?

Is COS UnAsserted when the Squelch is open (Y/N)?

Is LOOP Asserted when the Squelch is closed (Y/N)?

Is LOOP UnAsserted when the Squelch is open (Y/N)?

Always hit "Enter key" unless the value other than default is required. Note the user should use the "Y" key if the default value needs to be changed.

6.4 Line Calibr ation Pr ocedur e

R50> cal line

This procedure is used for calibrating the RF RSSI level reading, FM modulation

(deviation) reading. Also this procedure is used to set the 600 Ohm audio line output level, Noise squelch level and Carrier squelch level. Simply follow the instruction of the software as bellow:

Attach an RF signal generator to the input.

Set the RF output to 37.5MHz, and an input level of -110dBm with a 1kHz tone and 3kHz deviation.

Adjust the Volume Pot until the DIR AUD output


is 388mV.(eqvt to 0dBm into 600 ohms)

Enter < RET> when done.

Set the RF signal generator's output to -60dBm


rssi_scale is 0.417dBm/dac step, and rssi offset is -137.500dBm)

Adjust the Modulation to only 1KHz max deviation


deviation_scale is 1.000dBm/dac step, and deviation offset is .000dBm

Adjust the Carrier Squelch to the desired level

Enter < RET> when set.

-99.5

--- for example

Enter the Fast Noise Threshold(in dBm):

Enter the Carrier Alarm Threshold(in dBm):

Set the RF generator output to the desired level ( < -105dBm ), and adjust the N.SQ adjustment counter clockwise until the squelch opens, thence turn it clockwise until the noise is muted.

Enter < RET> when done

6.5 The " Refer ence" Calibr ation Pr ocedur e

R50> cal ref

To compensate for crystal ageing and other parameters that drift, the following procedure should be performed approximately once per year.

Open the cover of the receiver, find out the test point TP209 on receiver PCB, using a frequency counter to measure the frequency and follow the instruction as bellow:

Measure the ECLK frequency, accurate to 0.5Hz

and enter the result(in MHz, eg 7.3727965)

Measure the E clock frequency again, and enter yes(y/Y) if less than 1Hz from prev. freq, or re-enter the frequency

Connect an RF generator to the input and with output freq of 37.5MHz and output level of -100dBm


7 SPECIFICATIONS

7.1 Over all Descr iption

The receiver is a frequency synthesized, narrow band, HF/VHF, FM unit which can be used in conjunction with transmitter and power supply modules as a base station, or it can operate as a stand alone receiver. All necessary control and

600 ohm line interface circuitry is included.

7.1.1 Channel Capacity

Although most applications are single channel, the R50 can be programmed for up to

256 channels, numbered 0-255. This allows a network administrator to program every receiver, in every site, the same way. By setting each site up to select which of the 256 channels is appropriate, any receiver can be plugged


into any position, in any site, without the need to perform on-site reprogramming. This can be convenient in maintenance situations.

The parameters that can be defined on a per channel basis are:

•

The frequency, or if scanning is enabled, the list of frequencies to be scanned.

•

If scanning is enabled, the selection of a priority frequency (if there is one), and how often it is checked.

•

The CTCSS tone, or tones, expected on each frequency, or, DCS code expected on each frequency.

•

The delay from the opening of the squelch till the assertion of the COS output, or LOOP output.

•

The delay from the closing of the squelch to the negation of the COS or LOOP output.

•

Whether or not LOOP and/or COS should be asserted when the squelch opens, depending on which frequency, and/or CTCSS tone, is detected.

•

Whether de-emphasis should be applied to the tuned signal or not depending on which frequency the receiver is tuned to.

•

Offsets for carrier strength or SINAD: the user can allow individual frequencies to have higher or lower thresholds for SINAD or carrier strength.

7.1.2 CTCSS

Full EIA subtone Capability is built into the modules. The CTCSS tone can be programmed for each channel. This means that each channel number can represent a unique RF and tone frequency combination.

7.1.3 DCS

From Rev. 4 hardware and Rev. 4 firmware, support for DCS codes is supported.

DCS code generation can be enabled on a per channel basis. If enabled, the receiver will not open the squelch unless it is receiving the nominated DCS code, or one of its valid transformations. If it stops receiving these DCS codes, the squelch will close.

7.1.4 Channel Pr ogr amming

The channel information is stored in non-volatile memory and can be programmed via the front panel connector using a PC, and/or RF Technology software.

7.1.5 Channel Selection

Channel selection is by eight channel select lines connected to the rear panel that mounts on the rear DB25 female connector.

A BCD active high code applied to the lines selects the required channel. This can be supplied by pre-wiring the rack connector so that each rack position is dedicated to a fixed channel. Alternatively, thumb-wheel switch panels are available.

By redefining “illegal” BCD codes, users can also encode channels from 100 – 255.

7.1.6 Micr opr ocessor

A microprocessor is used to control the synthesizer, tone squelch, calibration, fault monitoring and reporting, RSSI reading, deviation measuring, option setting and facilitate channel frequency programming.


7.2 Physical Configur ation

The receiver is designed to fit in a 19 inch rack mounted sub-frame. The installed height is 4 RU (178 mm) and the depth is 350 mm. The receiver is 63.5 mm or two Eclipse modules wide.

IF filter whose bandwidth is suitable for 20kHz or

If the MSN is less than 9, but the LSN is greater than 9, then the channel number is defined by the formula:

10*LSN+MSN;

Logic Input Levels - High for <1.5V, Low for >3.5V

Internal pull up resistors select channel 00 when all inputs are O/C.


7.4.21 Car r ier Oper ated Switch (COS) Output

The carrier operated switch output is via an Opto-coupler. Collector and emitter connections are available to allow connection for source or sink.

The Opto-coupler can be linked inside the receiver to be on when a carrier is detected or to be on in the absence of carrier.

Internal connections are provided by a relay so that 12VDC can be connected to the

600 Ohm line for use over a single pair.

7.4.22 COS Output Cur r ent Sour ce/Sink, Collector Voltage

Ic = 10 mA Maximum

Vc = 30 Volts Max

7.4.23 CTCSS

The CTCSS decoding is provided by U602. This provides programmable decoding of all 38 EIA and 12 other common tones. See Appendix C for the full list of tone squelch frequencies.

U602 is accurate to within +/- 0.2Hz. The firmware will accept as valid any received tone that is within

±

1.5 % of the nominated tone.

7.4.24 DCS

From Rev. 4 hardware and Rev. 4 firmware, support for DCS codes is supported. If

DCS is enabled, the receiver will set the CTCSS chip (U602) into a mode whereby it expects NRZ data at 134.4 bps. On the reception of each bit of data, that bit and the previous 22 bits of data, are parsed to check if they are a valid

Golay code with 3 or less bit errors. If these 23 bits are valid, then the code is extracted and compared with the code defined for that channel, or one of the transformations of that code. If the squelch is closed, and a period of 120 milliseconds occurs during which all valid codes tested match , then the squelch will open. If the squelch is open, and no valid match is found for a period of 120 millseconds, then the squelch is closed. When the carrier level is below the fast noise threshold, the firmware increases the delay used to close the squelch to 300 milliseconds.

DCS codes are received inverted by U602, ie “0” to “1” transitions are received as decreases in carrier frequency. To compensate, the firmware inverts all NRZ data received by U602.

Most DCS codes have more than one transformation, for example code 023 can be detected as 340 and 766. If any of these codes are defined to be the code for a channel, then the receiver will accept the others as being equivalent.

Some receivers will allow the inverted codes to also be equivalents. For example the inverted codes for the previous example are 754, 437, and 011. The R50 does not treat them as equivalents. If the transmitter being tuned to inverts the code, then the user should program the receiver with one of the inverted codes

7.4.25 Exter nal Squelch Input

An external input is provided to squelch or mute the receiver audio output. This may be used in conjunction with an external decoder or to mute the receiver during transmissions.


The External Squelch Input can be connected to the T/R Relay pin on Eclipse transmitters mute the receiver during transmission.
