Graphic
LCD Panel. Revolutionary new generation FM transmitter or exciter
with graphic LCD front panel full control and measurements. Front panel
instant frequency programmability, RF power settings, audio settings,
deviation controls, alarms status are only the main facilities available
in the graphic display.
Suitable for digital audio. FM exciter of latest generation
fully compatible with digital audio. In fact the amplitude and group delay
linearity extended to the sub-sonic frequencies band to avoid the low-frequencies
overmodulation and phase distortion exalts the musical quality of digital
audio. Even the musical quality of traditional analog audio is emphasized.
0 ÷ 30 W maximum output power continuously adjustable
from front panel graphic menu selector. Ideal as stand-alone transmitter
or versatile exciter for power amplifiers.
87.5 ÷ 108 MHz. Instant frequency programmability using
the front panel graphic display menu. No tuning or adjustments required.
Stereo coder. High performances digital built-in stereo
coder (/S option) with stereo separation (> 65 dB) and signal/noise
ratio ( > 80 dB) for a top sound quality.
Remote control. Full remote control capability thanks
to the microprocessor on the front panel control board: power output adjustment,
deviation adjustment, general on/off, alarm reset, forward and reverse
power measure, frequency deviation measure and alarm status are the main
possibilities of remote control function.
Top quality sound. The modulated signal is characterized
by an excellent signal/noise ratio and by negligible residual AM: all
this for the best quality of the broadcast signal.
High frequency stability in short and long terms is assured
by Digital Phase Locked Loop circuit with low drift oscillator. For more
frequency stability the /HS option is available.
Deviation limiter. A CCIR standard deviation limiter
limits the maximum frequency deviation meeting the international requirement
in order to avoid adjacent channels invasion in case of accidental overmodulation:
all this without affecting the audio modulation quality.
Electronic protections automatically protect the equipment
in case of load mismatching (VSWR) or transmitting frequency error (LOCK)
or overtemperature (TEMP). Every alarm event is displayed by a front panel
general ALARM led and more details are available using the front panel
display menu (type of alarm, date and time of the alarm, etc…).
Output low pass filter. It assures a pure RF spectrum,
according to the international requirements.
Power supply. High efficiency switching mode power supply
gives greater reliability and reduces the power consumption. Battery operation
is also available as (/VDC) option.
Meets or exceeds the international standards for safety
and electrical specifications. |
