TVS 3004 Pro Channel Generator

The TVS-3004 PRO channel generator is a high quality digitally synthesized subcarrier system. The TVS-3004 can be used for voice or data communication. PRO channel service is 3kHz deviated carrier at 102.271kHz (6.5 times Fh). PRO channel can be used for data transmission back to the station or as an IFB signal to remote vehicles or points. The PRO channel can be used with most stereo ready transmitters. Your station does not have to broadcast in stereo to use the PRO channel.

Full Audio Processing

The superior performance of the TVS-3004 starts with a low distortion dual band limiter and clipping audio low-pass filter. Our processing gives your voice applications clear, consistent modulation levels, ensuring maximum service range. Optional low frequency roll-off and voice boost jumpers allow you to tailor audio presence easily.

Direct Data Connections

The TVS-3004 offers two direct data input ports via rear mounted RS-232 and BNC connectors. The data input levels are adjusted separately by a front panel mounted mounted control. Both data inputs are DC coupled for compatibilityu with slow speed data schemes.

Rock Stable Subcarrier

The heart of the TVS-3004 is its digitally synthesized subcarrier generator. This time and frequency stable design can handle any type of audio or data transmission used with the PRO channel today. A patented overshoot-corrected low-pass filter provides excellent audio peak control and crosstalk prevention into the SAP channel. Subcarrier deviation level is controlled by a front panel mounted control and is monitored by a Peak Modulation LED indicator. The subcarrier injection level is adjusted via a front panel mounted control.

Flexible Control Options

The TVS-3004 has three modes of operation. The unit may be set for subcarrier "ON" operation. In this mode there is always a subcarrier output. The second mode is the auto setting which allows automatic "turn-on" operation of the unit when program material is supplied to the unit. After program material is removed, the subcarrier will mute after a preset time. The delay time and mute level functions are adjusted on the unit's front panel. The third mode of operation allows subcarrier on and off remote control via rear panel contact closures. This carrier on/off control is smooth and "squelch-belch" free due to a unique carrier muting design.
