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.
Mono/Stereo/MPX
Tests comparing the audio performance of a CDPlayer/PTXLCD/Tuner combination and the CD-Player itself have
demonstrated the “TRANSPARENCY” that can be achieved with
PTXLCD exciters.
Professional FM Exciter
The response from several groups of listeners in sound trials was
always the same: NO DISCERNIBLE DIFFERENCE.
87.5 - 108 MHz

exciters
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.
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.

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.
