™

a versatile receiver

with world-proven

performance

The RF-590A is a high performance LF/MF/HF receiver ideally
suited for a wide range of fixed site, transportable and
shipboard communications or surveillance applications.

The low noise synthesizer and high-intercept front end provide
high instantaneous dynamic range and result in excellent
performance in the face of severe spectral congestion in the
LF/MF/HF bands. Addition of the optional internal digitally­tuned preselector further enhances this performance for severe
collocation environments.

The receiver covers 10 kHz to 30 MHz in 1-Hz increments and
provides memory storage for up to 100 channels of frequency,
mode, bandwidth, and AGC time constant settings. Modes
of operation include USB, LSB, ISB (optional), CW, AM, and FM
and are supported by a range of six IF bandwidths and four
AGC speeds, including a LINK 11-compliant DATA selection.
Optional filters are available which are fully compliant with
LINK 11 and suitable for other high speed HF modems to
9600 bits per second.

The RF-590A is fully remote controllable for applications such
as large multi-channel systems and split-site configurations.
Essentially all parameters may be controlled and signal strength
and BIT results monitored via the MIL-STD-188, RS-232, and
RS-422 interfaces pr

ovided.

Built-in test features diagnose and isolate malfunctions to the
module level allowing for rapid troubleshooting and module
replacement, minimizing time to repair.
