BLUES30/50NV
ELETTRONICA
The RF power section uses one MOSFET module able to deliver 30/50W.
The working frequency is assured by a thermally-compensated, reference oscillator
working within a phase-locked loop (PLL). The
BLUES30/50NV
reaches frequency
lock within a maximum of 30 seconds.
The
BLUES30/50NV
is able to work in all range frequency without calibration and
setting operation.
The microprocessor system includes an LCD display and push-button panel for
interaction with the user, and implements the following functions:
• Setting of output power
• Setting of working frequency
• Setting of Mono or Stereo operation
• Setting of preemphasis
• Setting of impedance on Left&Right and MPX channels.
• Activation and deactivation of power delivery
• Activation and deactivation of clipper operation
• Measurement and display of the working parameters of the exciter
• Communications with external devices
Four LEDs indicate the machine status and are found on the front panel:
ON
,
LOCK
,
FOLDBACK
,
RF OFF
.
The exciter’s management software is based on a menu system. The user can
navigate between the various submenus by using the knob (encoder) placed on
front panel.
On rear panel there are Mains connector, audio input and RF output connectors,
telemetry connector, protection fuse, two inputs for modulated signals on subcarriers
from special external encoders normally used in Europe for RDS (Radio Data
Systems) transmission.
