The receiver's robust front-end is equipped with an ultra-high-linearity amplifier which results in exceptional strong-signal performance while at the same time offering excellent sensitivity.
The WR-G65DDCi also features optional external reference clock inputs and outputs, coherence clock input, 1PPS pulse input as well as an FPGA interface, ready for phase-coherent system configurations such as in high performance interferometer direction finding applications. In addition, stereo analog output is also possible, as well as wide audio (10 Hz-150 kHz).
Yet again, this is the first time a receiver of such advanced specification and unique combination of features is being offered to the general marketplace.
The receiver is intended for government, military, security, surveillance, broadcast monitoring, industrial and demanding consumer applications.
Easily installed to any modern computer using a PCIe slot, the Excalibur Sigma receiver represents an excellent multi-purpose mobile and stationary solution for advanced HF/VHF monitoring and surveillance.
