1 OPERAT IN G INST R UCTIONS

1 Oper a ting Instr u ctions

1.1 Front Panel Controls and Ind icators

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 t he noise squelch t hreshold.

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.

Turn the N.SQ.

screw clockwise until the

until the noise in the speaker is muted.

WARNING

Changes or modificat ions not expressly approved by RF

Technology could void your authority to operate this equipment. Specifications may vary from those given in this document in accordance with requirements of local authorities. RF Techno logy equipment is subject to continual improvement and RF Technology reserves the right to change performance and specification without further

notice.

Page 2 RF Technology R50

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 t he 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.

until the LED just comes ON.

1.1.5 LINE

The LINE trimpot is used to set t he 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 F ront Panel Ind ica tor 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 t he 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.

Table 1: Interpretations of LED flash cadence

2 R eceiver O p t ions

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 descript ion of these global parameters

2.1 Serial I/O Par a meters

There are two serial ports. There is t he 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 R eceiver Low Bat t ery 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 LO OP 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 receiver s, the user can select to reverse the application of 12V,

ie 12V

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 CO S Source/Sink Select

The COS output can have four possible states:

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,

open: COS+ and

COS- are not shorted together, but both are electrically

isolated

In states (a) and (b), t he 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.

Page 4 RF Technology R50

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 C OS Pola rity

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 o pens (state (c) above), or open them when the squelch closes. The user can reverse this as well.

2.6 Noise Blan ker

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 Advan ced Slot Selectable Parameters

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 “priorit y”. 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 t uned to t he 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 t o inhibit the assertio n 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

RF Technology R50 Page 5

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 Standa r d Chann el Para meters

Each channel can set the following standard parameters:

a) frequency, b) one CTCSS tone, or DCS code.

program channel information. See the

WinTekHelp

users manual for further

information.

5 Circuit Descr ipt ion

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 R 50 Ma ster Sch emat ic (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 M icrop rocessor (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 o scillator 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.

Page 8 RF Technology R50

FPSW1, FPSW2 and FPSW3 are t hree 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 t hat t he COS can be selected as +12VDC source or a free

switch.

COS_POLARITY is CPU o utput that when low t urns

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.

RF Technology R50 Page 9

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 t he 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 insufficie nt volts (< 4.65V) on pin 2 o f the MC33064D (U203), it

will keep its RES o utput 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 t he 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.

Page 10 RF Technology R50

U303A, U303D are buffers that isolat e t he 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 w ith 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 t he schematic as RF_AMP. It is up-

converted by mixer MX401 to create the 1

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, w ithout

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 t o 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 1st 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 2nd 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

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

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 o f 40dB attenuation at the adjacent

channel frequencies (25kHz channel spacing). C448, C477, L423 and

RF Technology R50 Page 11

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 t he 2nd IF to the 3rd 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 t hat becomes the 3

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

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 Volta ge Controlled O scilla t or (Sheet 5)

There are two similar VCO circuit s 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 o f the

oscillator is decided by t he tuning voltage of varactor D501. The capacit ance

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 filt er of the 1st PLL. Q503 forms a

gyrator circuit which reduces no ise 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

Page 12 RF Technology R50

the possibility of rep lacing MX401 with a mixer that requires a higher level of LO drive (but an improved IP3 figure).

5.6 Au dio Processing Section (Sheet 6)

The discriminator output from t he 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 t hen 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 5th 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 to nes, 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 a mplified 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 t he 600 ohm line output. U609D is the amplifier for the

direct audio output (DIR_AUD). The output level o f 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

RF Technology R50 Page 13

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 Generation 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 off-

board 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 off-

board 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 t he -

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 Align ment (Calibra t ion) P rocedure

6.1 Standa rd 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 I n vokin g the Calibr a t ion Proced u re Man ua lly

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

WinT ekHelp 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 t he Prompt Window” o ption from the main menu, t hey

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.

The reference oscillators are adjusted and calibrated

6.3 T h e "Miscellaneous" Calibr a tion Procedure

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 init ial calibration, at the factory, the service personnel will be prompted to enter these values).

RF Technology R50 Page 15

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

5.7).

Measure the voltage, a t 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 corr ect 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 t he 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 t han default is required. Note the user

should use the "Y" key if the default value needs to be changed.

6.4 L ine C alibr at ion Pr ocedur e

R50> cal line

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

(deviation) reading. Also t his procedure is used to set the 600 Ohm audio line output level, Noise squelch level and Carrier squelch level. Simply follow t he

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

Page 16 RF Technology R50

is 388mV.(eqvt to 0dBm into 600 ohms) Enter <RET> when done. Set the RF signal gener ator's output to -60dBm Enter <RET> when done. rssi_scale is 0.417dBm/dac step, and rssi offset is -137.500dBm) Adjust the Modulation to only 1KHz max dev iation Enter <RET> when done. 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 F ast Noise Threshold(in dBm): Enter the Carrier Alar m 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 T he "Reference" Calibr at ion Proced ur 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 Enter <RET> when done.

SPECI F IC AT IO NS

7.1 O vera ll Descr ip t ion

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 Cha n nel Capa city

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 s ite up to select which of the 256 channels is appropriate, any receiver can be plugged

RF Technology R50 Page 17

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 t uned signal o r 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 CTC SS

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 Cha nnel Pr ogra mm ing

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 Ch an nel 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. T his ca n be

supplied by pre-wiring the rack connector so that each rack position is dedicated to a fixed channel. Alternat ively, thumb-wheel switch panels are available.

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

7.1.6 Micr oprocessor

A microprocessor is used to control the synt hesizer, tone squelch, calibration, fault

monitoring and reporting, RSSI reading, deviation measuring, option setting

and facilitate channel frequency programming.

Page 18 RF Technology R50

7.2 P h ysical Configura t ion

The receiver is designed to fit in a 19 inch rack mounted sub-frame. The installed

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 t he

600 Ohm line for use over a single pair.

Ic = 10 mA Maximum Vc = 30 Volts Max

7.4.23 CT C SS

The CTCSS decoding is provided by U602. This provides programmable decoding o f

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 DC S

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 t he 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, t he 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, t he 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 na l Squelch Inp ut

An external input is provided to squelch or mute the receiver audio o utput. This may

be used in conjunction with an e xternal decoder or to mute t he receiver during transmissions.
