[Specification]  [Leaflet]  [CE / COTS]

The TEN-TEC RX-331 is a multi-mode HF receiver operating from 5 kHz to 30 MHz, fully synthesized and utilizing state-of-the-art Digital Signal Processing. DSP technology brings the performance and repeatability of expensive military grade communications receivers into the more economic range of commercial receivers.

The design flexibility of DSP provides 57 standard selectivity choices from 100 Hz to 16 KHz. It is also practical to customize filter bandwidths, shape factors and time delays to match unique customer requirements.

The RX-331 is designed specifically for remote controlled applications. Multi-drop RS-232 interface permits simultaneous operation of multiple receivers on a single network at baud rates from 300 to 19,200. Receiver may be controlled by either internal or external frequency reference and an optional high stability internal reference is available.

This receiver is a compact, rack mount unit only 1 3/4" high - ideal when available rack space is at a premium. Power consumption is a nominal 30 watts which can provide a measured advantage when comparing recurring system costs. All connections are arranged on rear panel. Front panel provides ON/OFF switch, headphone jacks with independent volume controls, serial port status indicators and power supply indicators.

Built-in Test (BITE) allows quick field verification of major subsystems. Built-in software provides a "field test" mode to allow complete receiver operation from a simple terminal without need of customer's complete control system.

CE / COTS

Due to the relatively small numbers of units sold in the UK, it has not been cost effective to submit the RX-331 for CE testing.  However, as its design is based on the RX-340 (which easily passed CE) it is not assumed to be a problem.  The two sister receivers were originally based on a USA DOD (Department Of Defence) 'TEMPEST' specification for commercial usage.  At this time, it is only possible to supply the RX-331 in the UK to government / commercial users on a COTS basis (Commercial Off The Shelf).  The RX-331 is a special order, delivery is usually about four weeks (subject to stock availability from TenTec USA, price on application.
