WR-G65DDCe Excalibur Sigma description :

The WR-G65DDC EXCALIBUR Sigma is a top performance, direct-sampling, software defined two-in-one HF/VHF receiver. Two independent and mutually exclusive inputs are provided, one for each range. Range A from 1 kHz to 88 MHz and range B from 118 to 190 MHz. A real time 88/72 MHz wide spectrum analyzer is included with a 64 MHz wide instantaneous bandwidth available for recording, demodulation and further digital processing. The receiver's superior performance results from its innovative, direct-sampling, digital down-conversion architecture along with the use of leading-edge components and design concepts. These all result in excellent sensitivity and dynamic range, highly accurate and stable tuning, and perfect demodulation. These key features create a receiver with wide application potential, including many operational and instrumentation features not usually found on receivers of any price category. More, for the main range from 1 kHz to 88 MHz eighteen preselection filters are available, in automatic or manual mode, as follow.

High-pass: 850 kHz, 2.4 MHz, 5.4 MHz, 11.8 MHz
Low-pass: 3.1 MHz, 5.4 MHz, 11.8 MHz, 23.3 MHz
Bandpass: 10 filters
Filter OFF: bypass

On the EXCALIBUR Sigma the entire 64 MHz DDC, digitally down-converted, bandwidth is available for recording and demodulation. And ideal tool for hopping frequencies analysis and full-band time-shifted monitoring. Three demodulators allow the simultaneous reception and decoding of radio signals within the entire band. The WR-G65DDCe also its ready for phase-coherent system configurations such as in high performance interferometer direction finding applications. The receiver interfaces to a Windows-compatible PC via USB3.0, or 1 Gb Ethernet LAN port with PoE (Power over Ethernet functionality). The receiver is very well shielded against interference, making it possible to operate in a noisy computer environment. Its modest power requirements are less than 12 watts. While connected via a LAN interface, thanks to PoE built-in functionality, the receiver can be operated and powered via a long Ethernet cable connection.

WR-G65DDCe Excalibur Sigma options :

The following two factory-fitted hardware options are available. G65DDCe/XR, includes an additional SMA connector which can be used to connect an external 10 MHz reference oscillator for the highest possible frequency accuracy. The reference oscillator can be either sine or square wave between -5 to +10 dBm. G65DDCe/RO, includes an additional SMA connector, which can be used to output the 10 MHz reference frequency. This is useful for situations where the receiver's internal oscillator is to be used as a reference for other equipment.
