R6201 is an Ultra-Low SWAP (Size, Weight and Power) multi-channel receiver that, depending on the software configuration, can be used as a C-ESM sensor, a C-ESM sensor with COMINT capability, and a COMINT receiver. The size of R6201 makes it the perfect solution for tactical SIGINT and COMINT operations. R6201 operates over the frequency range 20-6000 MHz with an instantaneous bandwidth of up to 20 MHz. The Software Defined Radio Architecture enables the implementation of future capabilities via virtually software-only updates. R6201 has a ruggedised built to be installed and operated in harsh environments, including EW Tactical vehicles and ships. R6201 can be powered using multiple sources, including BB-2590 NATO standard batteries. The Spectrum Monitoring Suite (SMS) software application runs on all LOG.IN C-ESM and COMINT systems, including R6201.
