Ten-Tec RX-400

(0.0/5) Add a review / View all reviews

Desktop Shortwave receiver

The RX-400 is a HF/VHF/UHF DSP Receiver. Tuning from 2 MHz to 3 GHz, the 1 ms synthesizer lock time provides realistic scan rates of 100 channels/sec or faster. One outstanding benefit of the DSP architecture is more than 50 built-in filter bandwidths from 100 Hz to 300 kHz, most useable in any detection mode. Strong signal handling is assured with a typical in-band 3rd order intercept of -3 dBm. In addition to conventional AGC presets, RX-400 includes a programmable mode. This allows the customer to build their own unique AGC characteristics specifically for a mission. A 21.4 MHz wideband IF output is provided with 6 MHz of bandwidth. The RX-400 includes both an RS-232 interface and TCP/IP. Receiver is modestly sized for ½ rack installation. Options will include: a Digital Data output, Narrowband IF output and a POTS interface to allow customer to remote unit anywhere with access to nothing but a phone line (no PC required).
