FM Transmitters

They are the models that have led BSI to success on the world market for solid-state transmitters. BSI has shown, many years ago, the ability to integrate the modulator and power amplifier in devices of very small size without giving up any of highest quality performances that more refined customers demand.

They are used as driver for amplifiers power up to 30 kW, but can also be conveniently used directly “in antenna” to realize transmitting stations at low-cost and very small footprint.
They are distinguished by reliability and unmatched feature.

Exciter ETB100 offers the high ETB series performance with 100 W output power.
Exciter in 3 rack units, switching power supply, equipped with telemetry.
Suitable both to drive medium power devices and to direct connection in antenna, to cover urban or mountainous areas.
Available with internal stereo board.

EASY USE

Interface LCD allows ease reading and setting operations of parameters. Final user can password-protect its chosen configurations.

audio quality

3 bars indicate frequency deviation (one for composite signal and two for left and right channels), with peak memory. A histogram on frequency and time axis allows precise monitoring of audio chain performances. An extremely wide and flat audio pass-band, without phase rotation, ensures that the MPX signal is transmitted at high quality without stereo degradation. A programmable ALC (Automatic Level Control) circuit acts on variations of the composite MPX signal, maintaining its level within the range defined by the user.

high performance

The RF amplifier is behind by a ROS meter, that in case of mismatch, gradually decreases the output power up to a safe value, the ETB exciters series might remain in this condition for an indefinite time without damage.

IPF (Intelligent Proportional Foldback)

IPF is an intelligent system that allows the transmitter to stay "ON AIR" into mismatched loads.

Telemetry

It allows remote monitoring and adjustment of the unit's operating parameters. Just an additional standard or GSM modem and HyperTerminal software (© Microsoft Windows) are required.

Modularity

Inside ETB exciters an expansion slot has been designed to place a Stereo Input and Stereo coder board (stereo filter, clipper and pre-emphasis).

PFC CIRCUIT

It allows the first 40 current harmonics emission reduction below the limits imposed by European standards (EN61000-3-2), better functioning of electronic equipment connected to the network, waveform of the current very close than sinusoidal.

REGULATORY COMPLIANCE

All ETB exciters meet the essential requirements of Directive 1999/5/EC.

CUSTOMIZATIONS

On request we can personalize the ETB display with the broadcaster's logo
