Pentek, Inc. (Upper Saddle River, NJ) has announced the SystemFlow Simulator for its Talon(R) analog and digital recording systems. The SystemFlow Simulator includes a virtual recorder server application that simulates disk and I/O transactions for a complete and realistic recording environment. Using either the standard SystemFlow graphical user interface (GUI) or the SystemFlow application programming interface (API), the virtual server provides live, interactive operation for training or development. The common user interface (UI) and API provides a simple transition from one Talon recorder to another. The SystemFlow Simulator demonstrates actual Configuration, Record, Playback and Status screens of the standard GUI, each with intuitive controls and indicators. The SystemFlow Signal Viewer includes a virtual oscilloscope and spectrum analyzer for signal monitoring in both time and frequency domains.
