General Description

SigDigIII™ is a high-resolution, high-speed data acquisition system specifically tailored for digitizing radio IF signals - a complete stand-alone system with a network interface.

The SigDigIII™ incorporates all the features that have made the SigDig line popular, such as deep memory, built in sampling clocks, combined wide band and narrow band capability, signal playback, and network connectivity. This newest generation provides 105MHz of bandwidth, 12-bit A/D resolution and a high speed USB 2.0 serial interface.

The compact size and ruggedness of the SigDigIII™ make it ideal for tactical and mobile surveillance applications. SigDigIII™ is housed in a compact, rugged, extruded-metal case, and is powered by DC or any worldwide AC source. Since it can be remotely accessed over any TCP/IP network, the digitizer can be deployed in a "leave-behind" scenario. As a companion to a laptop computer, it is the ultimate portable signal collection and analysis station.

Ease of use is a hallmark of Signami Digitizers. Whether using the universal cross platform software, the premier SignalWorks™ analysis software, or writing custom software to the open network interface, nothing beats the simplicity of the SigDigIII™.
