The SIGNALWORKS® 4 package of signal processing tools features highly specialized algorithms that are fully implemented and integrated for advanced signals analysis. SIGNALWORKS requires no programming or scripting. Coupled with input digitizing, the SIGNALWORKS package offers signal analysts a friendly alternative to the digital oscilloscope, spectrum analyzer, demodulators, and other specialized signal analysis hardware.

New with SIGNALWORKS is the ability to analyze randomized signals for overhead removal, justification and control bits, with demultiplexing capability along with interleaving and tributary definition. SIGNALWORKS® processing is compatible with the 7500TR real time TDM communications demodulator, and facilitates integrated analysis and processing of non-standard bit framing with overhead, justification, and control bit identification and removal.

SignalWorks 4 now has comprehensive Forward Error Correction (FEC) encoding/decoding capabilities including Reed Solomon and Viterbi convolutional codes. Reed Solomon block coding is fully programmable using any size block codes. Viterbi convolutional encoding and decoding is also fully configurable including the code generating polynomial, punctured codes; and includes all standard rates such as 1/3, 2/3, 3/4, and 7/8.

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™.

FSK, VFT, Modem and Fax Demodulation Software

WinDemod is a standalone software package that performs demodulation, demultiplexing, bit stream synchronization and back-end processing for commercially available voice grade modem (PSK/QAM) and voice frequency telegraphy (FSK/VFT) signals, as well as, complete Group 3 FAX processing.

This application is a powerful tool for processing and analyzing voice grade channel signals. Signals can automatically be processed or an operator can control individual signal parameters including modem type, rate, multiplexing format and coding. WinDemod is also capable of displaying real-time and collected constellation, text, and fax data.

WinDemod is utilized in several of our system offerings for the purpose of processing and analyzing collected input signals.
