Model LPV-3000 Video/Data Transmitter, Digital Service (Analog Compatible) The new EMCEE LPV SeriesTM represents the highest evolution in a low power VHF triple conversion design transmitter or translator using LDMOS technology. Inherently low distortion minimizes the need for extensive corrective circuitry and provides for excellent performance in lower power digital and analog applications.
Broadband circuitry complemented by modular packaging enables simplified maintenance with reduced spare requirements and at the same time provides a path for channel flexibility. A new generation, EMCEE designed, low phase-noise synthesizer/local oscillator chain provides built-in channel agility together with GPS/NAVSTAR or LORAN synchronizing capability for high precision frequency control and co-channel interference reduction. The Class AB amplifier design incorporates soft-fail technology, so one failed amplifier does not constitute a service outage. Hot-swappable plug-in power supplies provide for simple change out and optional N+1 or N+2 redundancy.
Front panel monitoring of all internal voltages and forward and reflected power is provided in an easy to read LCD display. A front panel color LED matrix provides an “at a glance” determination of the transmitter status and alarm modes. Web based remote control interfacing for critical transmitter functions and monitoring is available via the rear chassis connections. A standard browser is all of the software that is needed to remotely monitor and control the transmitter. The LPV Series is the perfect choice for transition into digital service and for lower power analog.
