1 OPERATING INSTRUCTIONS

WARNING

Changes or modifications 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 Technology equipment is subject to

continual improvement and RF Technology reserves the

right to change performance and specification without

further notice.

1Operating Instructions

1.1 Front Panel Controls and Indicators

1.1.1 PTT

A front-panel push-to-talk (PTT) button is provided to facilitate bench and field tests and

adjustments. The button is a momentary action type. When keyed, audio from the line input

is disabled so that a carrier with sub-tone is transmitted. The front-panel microphone input is

not enabled in this mode, but it is enabled when the PTT line on that socket is pulled to

ground.

1.1.2 Line

The LINE trimpot is accessible by means of a small screwdriver from the front panel of the

module. It is used to set the correct sensitivity of the line and direct audio inputs. It is

factory preset to give 60% of rated deviation with an input of 0dBm (1mW on 600

Ω

equivalent to 775mV RMS or about 2.2V peak-to-peak) at 1kHz. The nominal 60% deviation

level may be adjusted by measuring between pins 6 and 1 on the test socket, and adjusting the

pot. By this means an input sensitivity from approximately -30dBm to +10dBm may be

established.

An internal jumper provides a coarse adjustment step of 20dB. Between the jumper and the

trimpot, a wide range of input levels may be accommodated.

1.1.3 POWER LED

The PWR LED shows that the dc supply is connected to the receiver.

1.1.4 TX LED

The TX LED illuminates when the transmitter is keyed. It will not illuminate (and an Alarm

cadence will be shown) if the synthesizer becomes unlocked, or the output amplifier supply is

interrupted by the microprocessor.

2.8 JP9/10/11: dc Loop Configuration

Dc loop current on the audio pair is normally sourced externally. The Eclipse exciters loop

the current through an opto-isolator. When the current flows the exciter keys up.

An alternative arrangement is possible. The exciters can source the current and an external

device can provide the dc loop.

These three jumpers select the appropriate mode.

2.9 JP16: Direct Digital Input (Rev 4 or Higher)

Some trunking controllers have digital encoding schemes which operate to very low

frequencies. The elliptical filter, used as a 250Hz low pass filter in the tone section, can

___________________________________________________________________________

2 TRANSMITTER INTERNAL JUMPER OPTIONS 2.10 JP17: Bypass Low Pass Filter

cause excessive pulse edge distortion of the trunking controller’s digital signals. In such

circumstances, JP16 allows a user to bypass the low and high pass filters in the

tone input

section. See also 2.12 - JP22: If direct tone input is selected, then JP22 should be removed

(open)

Condition Position

Normal Tone Input 1-2*

Direct Tone Input 2-3

2.10 JP17: Bypass Low Pass Filter (Rev 4 or higher)

Some trunking controllers have digital encoding schemes that require the low pass filter in the

tone input section to be bypassed. JP17 allows this. Normally JP17 is open circuit. Placing

a link across it will bypass the low pass filter.

In conjunction with this change, it sometimes may be necessary, depending on the type of

trunking controller used, to add a 100K resistor in the place reserved for R157.

2.11 JP19: Alarm Output (Rev 4 or higher)

The main audio transformer (T1), is connected to the Line IP1 and Line IP4 pins on P3.

These two pins constitute the main audio input for the exciter. The centre taps of the audio

transformer, though, are brought out on Line IP2, and Line IP3. These can be used as

alternate audio pins for larger signals, or to directly access the dc loop sense circuitry. JP19

allows an alternate use for Line IP2 (pin 7 of P3). In the alternate position for JP19, the

ALARM signal (the signal that drives the ALARM LED itself) is connected to pin 7 of P3.

The ALARM signal when asserted is low active; when unasserted, it pulls high to +9.4V

through an LED and a 680 ohm resistor.

Condition Position

P3, pin 7 connects to center tap of transformer T1 1-2*

P3, pin 7 connects to ALARM signal 2-3

2.12 JP22: Use Tone- as a Direct Digital Input (Rev 4 or higher)

JP22 is normally shunted with a jumper, which connects Tone- on P3 (pin 18), as the negative leg of the

Tone input pair. Removing this jumper disconnects Tone- from this path and allows the use of the

Tone- pin to be used as a direct digital input. See also 2.9 - JP16: If this jumper is removed, then JP16

should be in the alternative position (Direct Tone Input).

2.13 JP23: Connection of DMTX Board (Rev 4 or higher)

When a DMTX board is connected to an exciter, there is provision for digital or audio modulation of the

reference osciallator and the VCO. The digital signal is input via the DB9 rear connector and the audio

input signal is via the Line inputs on the standard DB25 rear panel connector.

Channel and Tone Frequency Programming

Channel and tone frequency programming is most easily accomplished with RF Technology

TecHelp software or the Service Monitor 2000 software. This software can be run on an IBM

compatible PC and provides a number of additional useful facilities. DOS and 32-bit versions

are available.

TecHelp allows setting of the adaptive noise squelch threshold, provides a simple means of

calibrating the forward and reverse power detectors, setting the power alarm preset levels, and

enabling transmitter hang time and timeout time limits. TecHelp can be supplied by your

dealer, distributor or by contacting RF Technology directly.

5 CIRCUIT DESCRIPTION 5.1 VCO Section

5Circuit Description

The following descriptions should be read as an aid to understanding the block and schematic

diagrams given in the appendix of this manual.

5.1 VCO Section

The Voltage Controlled Oscillator uses a bipolar junction FET Q19

which oscillates at the

required transmitter output frequency. Varactor diodes D25 and D26 are used by the PLL

circuit to keep the oscillator on the desired frequency. A second varactor diode D3 is used to

frequency

modulate the VCO. Transistor Q20 is used as an active filter to reduce the noise

on the oscillator supply voltage.

The VCO is keyed ON by the microcontroller through Q10. It is keyed ON when any of the

PTT inputs are active and OFF at all other times.

The VCO output is amplified and buffered by monolithic amplifiers MA2 and MA3 before

being fed to the PLL IC U6.

Amplifiers MA1, MA4 and MA5 increase the VCO output to approximately 10 mW to drive

the power amplifier. MA1 is not switched on until the PLL has locked and had time to settle.

This prevents any momentary off channel transmission when the transmitter is keyed.

5.2 PLL Section

The frequency reference for the synthesiser is a crystal oscillator using transistors Q26 and

Q27 and crystal Y3. The temperature stability is better than 5 ppm and it can be synchronised

to an external reference for improved stability. External reference option board 11/9119 is

required when using an external reference.

A positive temperature coefficient thermistor, XH1, is used in versions intended for operation

down to -30 degrees Celsius. The thermistor heats the crystal's case to maintain its

temperature above -10 degrees thus extending the oscillator stability of 5 ppm down to -30

degrees ambient.

Varactor diodes D27-30

are used to frequency modulate the oscillator. The processed transmit

audio signal from U7b varies the diodes bias voltage to modulate the reference frequency.

This extends the modulation capability down to a few Hz for sub-audible tones and digital

squelch codes. A

two point modulation scheme is used with the audio also being fed to the

VCO to modulate the higher audio frequencies.

The 12.8 MHz output of Q27 is amplified by Q28 and Q29 to drive the reference input of the

PLL synthesiser IC U6. This IC is a single chip synthesiser which includes a 1.1 GHz pre-

scaler, programmable divider, reference divider and phase/frequency detector. The frequency

data for U6 is supplied via a serial data link by the microcontroller.

___________________________________________________________________________

RF Technology T800 Page 14

5.3 Power Amplifier 5 CIRCUIT DESCRIPTION

The phase detector output signals of U6 are used to control two switched current sources. The

output of the positive and negative sources Q3 and Q6, produce the tuning voltage which is

smoothed by the loop filter components to bias the V.C.O. varactor diode D3.

5.3 Power Amplifier

The 10 mW output from the main board connects to the power amplifier board through a short

miniature 50Ω coaxial cable.

Q2 on the power amplifier board increases the signal to approximately200mW.

The bias of

Q2 is controlled by Q1 and the power leveling circuitry to adjust the drive to the output

module U2.

U2 increases the power from the driver to 30 watts before it is fed to the directional coupler,

low pass filter and output connector. The directional coupler detects the forward and reverse

power components and provides proportional dc voltages which are amplified by U1a and

U1b.

The forward power voltage from U1a and U1b are compared to the present DC reference

voltage from RV1.

The difference is amplified by U1c, Q3 and Q4. The resulting control

voltage supplies Q2 through R10, R12 and completes the power levelling control loop.

5.4 Temperature Protection

Thermistor RT1 on the power amplifier board is used to sense the case temperature of the

output module U2. If the case temperature rises above 90 degrees C, the voltage across RT1

will increase and transistor Q5 will be turned on. This reduces the dc reference voltage to the

power regulator which inturn reduces the outpower by 6-10dB.

5.5 600Ω Line Input

The 600Ω balanced line input connects to line isolation transformer T1. T1 has two 150Ω

primary windings which are normally connected in series for 600Ω

lines. The dual primary

windings can be used to provide DC loop PTT signaling or a 2/4 wire hybrid connection. All

four leads are available at the rear panel system connector.

The secondary of T1 can be terminated with an internal 600Ω

load through JP5 or left un-

terminated in high impedance applications.

5.6 Direct Coupled Audio Input

A high impedance (10k

Ω) direct AC coupled input is available at the system connector. The

direct coupled input connects to U9a which is configured as a unity gain bridge amplifier.

The bridge configuration allows audio signal inversion by interchanging the positive and

negative inputs and minimizes ground loop problems. Both inputs should be connected, with

one lead going to the source output pin and the other connected to the source audio ground.

___________________________________________________________________________

RF Technology T800 Page 15

5 CIRCUIT DESCRIPTION 5.7 Local Microphone Input

5.7 Local Microphone Input

The local microphone input is provided for use with a

standard low impedance dynamic

microphone. The microphone output is amplified by U9a before connecting to analogue

switch U10a. U10b inverts the local microphone PTT input to switch U10a ON when the

microphone PTT button is pressed. U10a is OFF at all other times.

The local microphone audio has priority over the other inputs. Activation of the local

microphone PTT input switches OFF the audio from the line or direct inputs through D16 and

U10c

5.8 CTCSS and Tone Filter

The CTCSS encoder module H1, under control of the main microprocessor U13, can encode

all 38 EIA tones and (on some models) additional commonly-used tones.

The tone output of H1 connects to jumper JP8

which is used to select either H1 or an external

tone source. The selected source is coupled to U9c which is a balanced input unity gain

amplifier. The buffered tone from U9c is fed to 300 Hz low pass filter U7c.

On Rev 4 or later revisions, the low pass filter can be by passed by inserting a jumper onto

JP17.

RV3, the tone deviation trimmer, is used to adjust the level of the tone from U7c before it is

combined with the voice audio signal in the summing amplifier U7a.

Back to back diodes D4 and D5 limit the maximum tone signal amplitude to prevent

excessive tone deviation when external tone sources are used.

The subtone amplifier, filter and limiter can be bypassed on Rev 4 or later exciters by

removing the link from JP22 and moving the link in JP16 to the alternate position.

5.9 Audio Signal Processing

Jumper JP4 selects either the line or direct input source. The selected source is then

connected to JP6. JP6 can be removed to provide 20 dB attenuation when the input level is

above 10 dBm to expand the useful range of the line level trimmer RV4. The wiper of RV4 is

coupled to the input of the input amplifier U9d. U9d provides a voltage gain of ten before

connecting to the input of analogue switch U10c.

The outputs of U10a and U10c are connected to the frequency response shaping networks

C52, R133 (for 750

µs pre-emphasis) and C61, R55 (for flat response). JP7 selects the pre-

emphasized or flat response.

The audio signal is further amplified 100 times by U7d. U7d also provides the symmetrical

clipping required

to limit the maximum deviation. The output level from U7d is adjusted by

RV1, the deviation adjustment, before being combined with the tone audio signal in the

summing amplifier U7a.

___________________________________________________________________________

RF Technology T800 Page 16

5.10 PTT and DC Remote Control 5 CIRCUIT DESCRIPTION

The composite audio from U7a is fed through the 3Khz low pass filter U7b. When the links

on JP23 are in their default state, the filtered audio is coupled to the TCXO voltage tuning

input and the modulation balance trimmer RV2. RV2, R99 and R98 attenuate the modulation

signal before applying it to the VCO via varactor D3.

When DMTX board option is required, Jumper JP23 allows the audio paths to be re-routed.

The DMTX board provides for an external digital modulation input signal.

When the two

links on JP23 are positioned in the middle of the 6 pin header, the audio from the exciter is

passed to the DMTX board via pin 5 of JP15, where the signal is conditioned and then

returned from the DMTX board via pin 2 of JP15, and passed to the two modulation points.

RV2 adjusts level of the audio used to modulate the VCO. This primarily effects the deviation

of audio frequencies above 500 Hz. RV2 is used to balance the high and low frequency

deviation to obtain a flat frequency response relative to the desired characteristic.

5.10 PTT and DC Remote Control

Two main PTT inputs are provided. The first, a direct logic level input, is connected to pin 3

of the system connector. The transmitter can be keyed by applying

a logic low or ground on

pin 3. Pin 3 connects to the PTT logic and microprocessor through D10.

DC current loop control can be used for remote PTT operation.

The current loop can be

configured by JP9, JP10 and JP11 for use with either a remote free switch or a remote

switched source.

Opto-isolator ISO1 is used to isolate the loop current signal from the transmitter PTT logic.

The loop current passes through the input of ISO1 and the output of ISO1 connects to the PTT

logic.

A bridge consisting of diodes D6, D8, D9 and D14 ensures correct operation regardless of the

current polarity. Q17 limits the current and D7 limits the voltage input of ISO1. Any low

voltage current source capable of providing 2mA at 4V or switching circuit with less than

4.8k¿ loop resistance can be used to switch the DC loop.

The test PTT button on the front panel and the local microphone PTT button will also key the

transmitter. Both of these also mute the line audio input. The microphone line also enables

that audio input.

A DMTX board can also cause the exciter to key up. When TX (or TTL_TX) signal is

received by the DMTX board, it pulls pin 6 of JP15 low, which in turn asserts the

PTT_WIRE-OR signal, causing the microprocessor (U13) to key the exciter up.

5.11 Microprocessor Controller

The microprocessor controller circuit uses a single-chip eight bit processor and several

support chips. The processor U13 includes non-volatile EE memory for channel frequencies,

tones, and other information. It also has an asynchronous serial port, a synchronous serial

port and an eight bit analogue to digital converter.

___________________________________________________________________________

RF Technology T800 Page 17

5 CIRCUIT DESCRIPTION 5.12 Voltage Regulator

The program is stored in U5, a CMOS EPROM. U4 is an address latch for the low order

address bits. U2 is used to read the channel select lines onto the data bus. U11 is an address

decoder for U5 and U2. U3 is a supervisory chip which keeps the processor reset unless the

+5 Volt supply is within operating limits. U1 translates the asynchronous serial port data to

standard RS232 levels.

The analogue to digital converter is used to measure the forward and reverse power, tuning

voltage and dc supply voltage.

If the processor detects that the PTT_WIRE_OR signal is asserted low, it will

attempts to key

the exciter up. If will first attempt to key the VCO through Q10, and if the LD pin goes high,

it will switch the 9.2 Volt transmit line through Q14 and Q16.

asserting Q16 has the effect of

also asserting the yellow Tx LED (D12) on the front panel, enabling the local 25W power

amplifier, and causing the T/R Relay output to be pulled low. D24 is

30 volt zener which

protects Q25 from both excessive voltages or reverse voltages.

Should there be a problem with either the tuning volts, or the battery voltage, the VCO

locking, the forward power, or the reverse power, the microprocessor will assert the ALARM

LED, through Q1. Depending on the setting of Jumper JP19, the ALARM signal can be

brought out on pin 7 of P3.

5.12 Voltage Regulator

The

dc input voltage is regulated down to 9.4 Vdc by a discrete regulator circuit. The series

pass transistor Q23 is driven by error amplifiers Q8 and Q18. Q9 is used to start up the

regulator and once the circuit turns on, it plays no further part in the operation.

The +5 Volt supply for the logic circuits is provided by an integrated circuit regulator U14

which is run from the regulated 9.4 Volt supply.

Jumper JP18 is not normally fitted to the board, and is bridged with a 12mil track on the

component side of the board. It is provided so that the 9.4V load can be isolated from the

supply by the service department to aid in fault finding.

Jumpers JP20 and JP21 are also not normally fitted on the board, and are usually bridged with

a 12mil track on the component side. They allow U14 to be isolated from its input, or its

output or both.

6Field Alignment Procedure

The procedures given below may be used to align the transmitter in the field. Normally,

alignment is only required when changing operating frequencies, or after component

replacement.

The procedures below do not constitute an exhaustive test or a complete alignment of the

module, but if successfully carried out are adequate in most circumstances.

7SPECIFICATIONS 7.1 Overall Description

7SPECIFICATIONS

7.1 Overall Description

The transmitter is a frequency synthesized, narrow band FM unit, normally used to drive a

50

watt amplifier. It can also be used alone in lower power applications.

Various models allow 2-25W of output power to be set across a number of UHF frequency

bands. All necessary control and 600Ω line interface circuitry is included.

7.1.1 Channel Capacity

Although most applications are single channel, it can be programmed for up to 100 channels,

numbered 0 - 99. This is to provide the capability of programming all channels into all of the

transmitters used at a given site. Where this facility is used in conjunction with

channel-

setting in the rack, exciter modules may be “hot-jockeyed” or used interchangeably. This can

be convenient in maintenance situations.

7.1.2 CTCSS

Full EIA sub-tone 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 Channel Programming

The channel information is stored in non-volatile memory and can be programmed via the

front panel test connector using a PC and RF Technology software.

7.1.4 Channel Selection

Channel selection is by eight

channel select lines. These are available through the rear panel

connector. Internal presetting is also possible. The default (open-circuit) state is to select

channel 00.

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.

7.1.5. Microprocessor

A microprocessor is used to control the synthesizer, tone squelch,

PTT function and facilitate

channel frequency programming. With the standard software, RF Technology modules also

provide fault monitoring and reporting.

An opto-coupler input is provided to enable dc loop keying over balanced lines or local

connections. The circuit can be connected to operate through the 600Ω

line or through a

separate isolated pair.

7.4.22 Programmable No-Tone Period

A No-Tone period can be appended to the end of each transmission to aid in eliminating

squelch tail noise which may be heard in mobiles with slow turn off decoders. The No-Tone

period can be set from 0--5 seconds in 0.1 second increments. The No Tone period operates

in addition to the reverse phase burst at the end of each transmission.3

7.4.23 Firmware Timers

The controller firmware includes some programmable timer functions.

Repeater Hang Time - A short delay or ``Hang Time''

can be programmed to be added to the

end of transmissions. This is usually used in talk through repeater applications to prevent the

repeater from dropping out between mobile transmissions. The Hang Time can be

individually set on each channel for 0 - 15 seconds.

Time Out Timer - A time-out or transmission time limit can be programmed to automatically

turn the transmitter off. The time limit can be set from 0-254 minutes in increments of one

minute. The timer is automatically reset when the PTT input is released.

7.4.24 CTCSS

CTCSS tones can be provided by an internal encoder or by an external source connected to

the external tone input. The internal CTCSS encoding is provided by a subassembly PCB

module. This provides programmable encoding of all EIA tones.

Some models encode certain extra tones.

Tone frequencies are given in table 4.
