Safety digital communication system

To test run time analog and digital communication systems, modulated signals are required in some applications. Similarly if we talk about analog and digital signal analysis then time domain analysis, frequency domain analysis, phase analysis, jitter analysis, logic analysis and protocol analysis are required in various applications. Frequency measurement of clock pulse and data recording with time are also required in some applications to record data between two acquisitions with minimum, average and maximum level provision. Scientech DesignLab3 is an ideal and compact USB powered high speed multi utility solution used in various applications. Along with analog, digital, protocols generation and analysis this USB based platform has capabilities to store, edit, personalize color of signal and screen, edit signal names, markers to analyze signal, print and many more features in its interactive and user friendly software.
