BROADBAND POWER

PJ 2500 MC

Features

1. Exceptionally high gain P.A. with relatively low input

2. Automatic gain control providing fixed output power even in case fluctuating drive power

3. High reliability, easy handling and consistent performance standard achieved among the various units due to total absence of tuning requirements

4. Very high efficiency of P.A., typically capable of more than 2 5 00W, output power with about 25 W of drive input power or only 5 W with the "/LD" (Low driving power option)

5. Composed of eight parallel 3 5 0 W R.F. power amplifier modules for highest reliability

6. These modules ere coupled through a Wilkinson Splitter and Combiner realized with

'Strip-Line Technology"

7. On the PJ 2500 MC front panel, by means a user-friendly graphic interface, all the amplifier's diagnostic and control parameters are displayed.

8. Protection for internal and antenna VSWR, excessive temperature and excessive drive power, with indicator light, which will put the transmitter driver in stand-by position in the event of failure

9. It's present a protection that in case of overcurrent on one 3 5 0 W P.A. Module reduces the voltage on the drain of the pair of 3 5 0 W modules interesting in faulty; then, this protection card cheek the status of each single R.F. Power Amplifier module's protection fuse

10. Compact size dimensions with built in power supply

11. Easily replaceable standard components

12. Advanced recycling overload and protection system that provides automatic re-start after about 10 seconds of stand-by in case of fault. This procedure is repeated four times and in case of persisting fault, the cycle restarts again after 90 seconds, for four more times. if fault still persists, the stop becomes permanent. If instead, during one of the re-starts the fault disappears the counting circuit system is resetted after a regular working period of 90 seconds

13. If one or more power amplifier modules fails (totally or partially) the amplifier automatically reduces output power to a safe value but continues transmitting

14. Terminals Strip for telemetry and remote control

90 dB signal/noise, 60 dB stereo separation.

Transparency and clearness with CD-quality FM.

RVR's PTX LCD exciter is the result of 25 years of experience in addition to the highest technology. PTXLCD has broken the barrier between CD sound quality and FM sound quality.

Tests comparing the audio performance of a CD-

Player/PTXLCD/Tuner combination and the CD-Player itself have demonstrated the “TRANSPARENCY” that can be achieved with

PTXLCD exciters.

The response from several groups of listeners in sound trials was always the same: NO DISCERNIBLE DIFFERENCE.

The best sold FM transmitter in the World! PTXLCD is a complete family of transmitters with several options to meet all the requirements of the professional broadcast operators everywhere in the world.

Designed at State of the Art to obtain the best audio quality and a superior transparency and clearness.

RS232 connector

Serial RS232 interface can be used to connect the PTXLCD exciter to the service PC of the local manteinance operator or, via modem, to the remote Technical Assistance Centre.

Different configurations can be made for Telecontrol and

Telemetry purpose.

exciters

Telemetry connector

8 analog input sockets, 2 relays output terminals and a I2C bus interface are the telemetry connectors available which data are displayed either on the LCD or on the PC monitor.

Remote connector

Two signal input sockets for the control of “foldback” output power are present on this connector: Direct and Reflected

Power Signal.

By adjusting the RFL trimmer, the Reflected Power Threshold level (Reflected Fold-Back) can be regulated: the exciter supplies the maximum possible Direct Power so that the

Reflected Power never exceeds the pre-set level. In this way, the transmission signal continues to be present, albeit more weakly, even in the event of very high VSWR levels (a typical example is the presence of ice on the antenna).

By adjusting the FWD trimmer, the Direct Power Threshold level (Forward Fold-Back) can be regulated: the modulator stabilises the Forward Output Power within 1dB in AGC.

This function is especially useful when the system includes tube amplifiers which are subject to output power variations in the event of fluctuations of the main voltage.The remote connector has 6 analogue input sockets and 2 relay output terminals.These signals are used to read measurements and to perform the on/off functions of the RF Power

Amplifier.There is also a I2C line for data transfer with other equipment (RVR’s TLC300, SCM4, TLC2000, etc.).

Personal computer link-up

It is possible to read and adjust through RVR's Supervisory

Software all the exciter's settings by linking the exciter to a

PC (either directly or by means of a telephone/radio modem). The System Manager can select the settings to be accessed by the user. Different properties, such as visibleyes/no, modifiable-yes/no, name, maximum level, unit of measurement, etc., for each setting can be adjusted. RVR's

Supervisory Software allows to use customized configurations for Type and Format of the data to be displayed. A telephone directory with name, number and automatic dialling of all stations makes it possible to set up a control and Supervisory System for a specific geographical area.

exciters

On the PTX LCD’s front panel, by means of a user-friendly graphic interface, are displayed all the exciter’s diagnostic and control capabilities, depending on the customized software and the installed options (DIGITAL-IN, DIGITAL-IN/DSP). The settings that can be monitored and adjusted with a standard SW-Version are the following:

Main menu

Display and Setting of the Working Frequency, Output Power, Reflected Power,

Audio Levels and Modulation.

From this menu, by selecting ADMIN, the user can move on to other Menus like:

RF Amplifier/Power Supply menu

Display of the characteristics of the RF operational power supply, power supply voltage, VCO voltage, RF power amplifier temperature, etc.

External Power/External Status menu

Display of Direct and Reflected RF power, Alarms, operating Voltages and Currents of the RF Power Amplifier.

Telemetry menu

Display of Telemetry Board readings, setting of Output Relays.

SCA/RDS menu

Display of the three SCA/RDS subcarrier levels, independently of audio modulation, thus enabling “on air” level readings.

General set menu

Display of communication settings, node number in case of networking and baudrate. Display of “jumper” operating mode settings.

Audio set/board set menu

On/off settings for the following functions: channels, clipper, input impedance, pre-emphasis, etc.

IAMLC menu

Intelligent Automatic Modulation Level Control settings. This system keeps the signal modulation constant even in the presence of significant variations in the input signal level (from -13 to +14dbm). By intervening in the final stage of transmission, by means of the digital input attenuator, it is possible to correct variations caused at other stages of the transmission chain (studio, STL, etc.).

Hardware Highlights

RVR's PTXLCD exciter was carefully designed to have superior parameters and operating stability. Several details permit to reach the state of the art. The audio inputs are equipped with RF filters and protection circuits all housed in a metal box. The connections between the box and the audio input board are by means of through-pass capacitors, ensuring that RF or any other kind of interference on the cables are discharged onto the Exciter casing. The total shielding of audio signal and RF circuits guarantee the quality of the radio-electric characteristics S/N, Spurious, etc. as well as full electromagnetic compatibility with other equipment.
