Integral Systems, Inc. (NASDAQ: ISYS) announced that its wholly-owned subsidiary, RT Logic, has more than doubled the bandwidth of its real-time T400CS Channel Simulator from 40 MHz to 85 MHz. The T400CS Channel Simulator generates precise and realistic signals for research and development (R&D) and test activities on communications equipment for satellites, ground stations, UAVs, aircraft, missiles, targets, and test range applications, to name several.
RT Logic also announced substantial price reductions on its 40 MHz bandwidth T400CS systems, which will continue to be available from the company. The T400CS Channel Simulator creates real-world test signals with absolute attention to the physics of Doppler shift, delay, attenuation, noise, interference and other perturbations, resulting in instrument output that is indiscernible from real-world signals. Fully phase-continuous operation of the T400CS is maintained as a broad range of signal impairments are applied, meaning that the instrument adds precise realism to test signals without introducing data errors. The Channel Simulator does this dynamically, based on the complex and often high-velocity relative motion of communications systems nodes.
RT Logic’s Channel Simulator allows an inter-satellite link, for example, be accurately tested in the lab with relevant portions of both satellite’s communications systems on a bench, and with uplink and downlink paths routed via cable or at RF through the Channel Simulator. Here, the communications system components may be separated by only a few feet, and are not in motion. Introducing the Channel Simulator between the systems, signals received by each are identical to those that would be received if the satellites were actually on orbit. This test methodology is the same for UAV system test and verification, aircraft systems, missiles, targets — basically any situation where receivers and transmitters are moving.
The Channel Simulator can be seamlessly controlled from Analytical Graphics, Inc.’s STK software with access to all the modeling power, visualization, and scenario development capacity of STK, along with integrated RT Logic Signal Generator and Spectrum Analyzer control. The Channel Simulator can also be commanded by user programs via TCP/IP socket communications over Ethernet connections, from supplied user interface software, and from user-created spreadsheets. RT Logic’s new 85 MHz T400CS Channel Simulator is available now at 266 MHz IF, L-band and/or S-band with 120-day delivery.
