Vytek PTX-150 Doc Ref : 7M393-1 Version C1 Page : 1  VYTEK - 2000 1. INTRODUCTION INTRODUCTION 1.1 GENERAL The VYTEK PTX-150 Paging transmitter is a state of the art DSP/DDS (Digital Signal Processor/Direct Digital Synthesis) based device capable of generating all paging modulation formats, and is designed as a general purpose transmitter for all speed paging systems. Construction of the transmitter is fully modular. Internally, the case is divided into compartments with PCB’s arranged in modules, all interconnected by plug/sockets. All modules can be replaced without the use of a soldering iron. Replacement modules do not require alignment or tuning. The VYTEK PTX-150 transmitter incorporates a universal AC supply and can also operate from a single DC supply for battery back up operation. Software permits the option of ”Hot standby” with auto changeover initiated by software selectable fault conditions. The VYTEK PTX-150 transmitter is designed for 100% duty cycle at up to 55°C ambient conditions and utilizes advanced cooling technology to maintain very low power transistor junction temperatures. This approach means assures ultra reliable power amplifier performance. The power amplifier temperature is monitored and if the temperature rises above a preset amount (35°C), the diagnostics system is alerted and the fan and cooling system is activated. The transmitter is protected by over temperature feedback control to the PA drive input and also incorporates auto fold back for high VSWR conditions. An external frequency reference input is designed to handle standard reference sources and will lock the transmitter to the external reference. An internal ±1 PPM TCXO (Temperature Compensated Crystal Oscillator) is provided as standard if no external reference is available. In POCSAG wide area systems, the carrier can be ”dithered” by what is known as a ”Black noise” algorithm, to minimize cancellation of equal amplitude carriers from adjacent transmitters. This technique has been used for at least 12 years and is superior to the Carrier offset method. High stability carriers are unnecessary for the carrier dithering technique. For high-speed ERMES and FLEX systems, the carrier can be offset in 1Hz steps.

On the exciter printed circuit board, the DDS/DSP circuitry generates a 10.7 MHz modulated signal, referenced to the internal TCXO or an external reference frequency source. (The reference source is selected in a software option). The external reference is only required when stability of the carrier better than ±1PPM is required. (Parameters such as rise time, absolute deviation, mode etc are all selectable in software). The 10.7 MHz modulated signal is processed through a filter before being applied to the first mixer. The LO input to the first mixer is a high quality 235 MHz un-modulated signal with very low phase noise. The mixing products are filtered and buffered with two stages of SAW filtering, and the low side product of 224.3 MHz is then applied to the second mixer. The Second mixer LO frequency is equal to final frequency + 224.3 MHz. Channel change is effected by the VCO supplying the second mixer. External Freq. standard. (optional) DSP/DDS circuits, microprocessor, modulator and TCXO Frequency converter and mixer VCO and channel synthesizer RF filter and preamp.Nominal 300 mW/50 ohms 20 Watt Driver Amplifier. AC Power supply (optional) 37 pin DIN Auto Diagnostics Circuits Power Splitter 75 Watt Power Amplifier 75 Watt Power Amplifier Combiner Filter RF OUT
Vytek PTX-150 Doc Ref : 7M393-1 Version C1 Page : 5  VYTEK - 2000 The final frequency output from the second mixer is filtered, buffered and amplified to 300 mW at 50 ohms, suitable for presentation to the Power amplifier modules. Note that the TCXO of 9.6 MHz supplies the DSP, first LO and second LO to provide the accuracy required for final frequency. The DSP circuitry actually uses 38.4 MHz, which is derived from, a crystal at that frequency phase locked to the 9.6 MHz TCXO. Note also that for high stability options, the 9.6 MHz TCXO is replaced when an external reference signal is applied to the BNC connector at the rear of the Transmitter. Selection of this function is via software. Automatic level control (ALC) of the exciter is affected by the on board Microprocessor in the Exciter module. The Exciter output is coupled via coaxial cable to the 20W driver amplifier in a separate compartment in the chassis. The driver comprises 2 RF amplifier stages, a Harmonic filter and directional coupler for generation of forward and reverse power voltage analogs. The output of the 20W driver amplifier goes into a power splitter, and the two 90 degree out of phase output signals from the power splitter are feed into two 75W power amplifiers. The outputs of the two 75W power amplifiers are then combined to produce 100W continuous RF output power. The forward and reverse power output is also monitored using a directional coupler. The exciter microprocessor computes VSWR from the directional coupler outputs. ALC is also affected in the PA to ensure stable output for all environmental and external conditions. The transmitter is designed to operate from a single +24VDC power source with the internal AC power supply generating the required voltage. A 37 Pin DIN female socket provides the connection for Data, Clock, mode, channel change, and PTT control from an external Line interface unit. (Refer to ‘Installation Instructions’ for details regarding pin connections). If no external PTT control exists, provision is made for PTT control by the detection of incoming data on the TX DATA (Lbit) pin of the 37 way connector. (Hang time for this automatic PTT control is selectable in software). A DB9 female socket provides access for either a PSTN dial modem or a PC. The transmitter can be monitored by a central or local computer for automatic diagnostics or polling. The PC and RDK software can be used on site to reprogram parameters of the transmitter.

Vytek PTX-150 Doc Ref : 7M393-1 Version C1 Page : 7  VYTEK - 2000 3. INITIAL INSTALLATION INSTALLATION The following equipment will be required to test the transmitter: - 1. A good quality 50Ω dummy load or 30 dB high power attenuator suitable for 150W continuous operation at 174 MHz and with a VSWR of better than 1.15:1. 2. A 486 or better PC with at least 8 Mbyte of RAM and one serial port, installed with RDK software. 3. A suitable cable to connect the serial port of the PC to the dial Modem port of the transmitter. Details of the required cable wiring are to be found in ‘CONNECTION TO THE NETWORK’ section of the manual. 4. A suitable AC lead to suit the country where the transmitter is to be tested. 5. A ”Thruline” wattmeter fitted with the appropriate insert. 6. Suitable low loss RF cables and connectors. Remove the VYTEK PTX-150 transmitter from its packing case and on a clean flat surface, carefully examine the transmitter for physical damage. Pay particular attention to the rear plugs and sockets. Verify that the rear cooling fan is free to rotate and does not have packing material in it, which may prevent the blades from rotating. Connect a good quality 50Ω dummy load rated for at least 150W continuous power at the frequency of operation of the transmitter; to the transmitter RF output ”N” connector on the rear panel. WARNING: ATTEMPTING TO OPERATE THE TRANSMITTER WITHOUT A PROPER LOAD CONNECTED TO THE RF OUTPUT PORT WILL VOID THE WARRANTY. The SONIK PTX-150 series Transmitters have a detailed and comprehensive test sequence programmed in and this program activates immediately power is applied to the unit. • If the beeps and light sequencing occurs as specified, then all is well. • If a dial Modem is connected, the start up sequence differs from that which would occur if a dial Modem was not connected. • With the transmitter located free of nearby objects which may block airflow through the unit, switch on the transmitter by connecting the AC power cord to the AC supply and operating the AC ON/OFF switch on the rear panel of the transmitter.
Vytek PTX-150 Doc Ref : 7M393-1 Version C1 Page : 8  VYTEK - 2000 • Connect a PC (fitted with RDK software) to either the front panel console or rear panel modem ports of the transmitter, activate the RDK program and verify correct connection by selecting the READ field on the Transmitter Configuration window. The screen then prompts by asking, ”ARE YOU SURE”? If the PC connection and the transmitter system are operational, respond ”YES” and the transmitter parameters are read into the PC screen. NOTE: Alarm trip points and operating parameters are preset in the factory and normally there will be no need to change these. For instructions on how to change the alarm settings and status parameters, use the PC mouse to revert to the TransmitterConfiguration window. Select the Alarm Settings field and note the presets. If Auto dial out functions are required (PSTN dial modem connected), use the mouse to select which alarms will initiate a dial back (Enable). A copy of all factory defaults can be saved onto hard disk by selecting the SAVE field and typing in an appropriate file name. The power up sequence is as follows 1. A tone is heard after power is applied and all front panel lights should be ON. 2. After approximately 5 seconds the LEDs on the front panel will go off in sequence starting with the FAULT and the only remaining LED left ON is POWER. 3. The tone then stops for half a second while the SONIK PTX-150 transmitter checks for a dial modem connected to the dial modem port. If no dial modem is detected then a brief tone is heard. If a dial modem is detected then a series of tones will be made by the SONIK PTX-150 transmitter to indicate that a dial modem was detected. For connections into a remote RDK network this test must pass if a dial modem is connected. 4. After an additional 5 seconds the SONIK PTX-150 transmitter will be ready for normal operation. NOTES: WHEN USING EXTERNAL TELEPHONE DIAL MODEM 1. When an incoming call is detected the buzzer will ring as an indication. 2. When a SONIK PTX-150 transmitter is connected the POWER LED blinks to indicate that the unit is on-line to the host RDK software.

CONNECTION TO NETWORK CONNECTION Once the transmitter has been configured for the network, it is now necessary to install the unit into the station and interface to the LIU (Line Interface Unit). • Verify that the antenna lead is connected to the station antenna. Install a Thruline Wattmeter in series with the transmitter and antenna lead. • If a PSTN connection and dial Modem are available, install the dial modem and connect it to the dial Modem port (on the rear of the transmitter). Use a standard DCE to DTE RS232 interface cable (usually supplied with the dial modem). • If an external frequency reference is used, select that option in software and connect the source via a 50Ω coaxial cable and BNC male plug to the BNC socket at the rear of the transmitter. • Identify the appropriate data, clock and mode control connections from the LIU and connect them to the appropriate pins on the DB37 connector at the rear of the transmitter. The correct connections will vary depending upon the LIU used and the mode of operation. Refer to Table 4.0.1 of pin outs for the DB37 connector.
