Software:

µ-Lab enables data from an unlimited number of digital and analog channels to be acquired, processed online, displayed and output again. As far as the hardware is concerned, data acquisition and output cards from a large range of well known manufacturers and, of course, the MOPS and PCM-Systems are supported. Sample rates from under 1 Hz to more than 100 kHz ( continuous ) or 500 kHz ( Burst ) are possible, depending on the hardware used. The acquired data can be distributed among an unlimited number of files. Even the basic µ-Lab version contains a wide range of trigger functions and action modules for limit surveillance, time control, data reduction and various smoothing algorithms. Each channel can be calibrated either linearly or non-linearly. By means of the online-graphic, an unlimited number of graphical objects can be displayed simultaneously: e.g. xt-digram ( incl. scroll and scope mode), xy-digram, bar diagram, numerical display or text switch. The properties - e.g. axis scaling, color, text fonts - can be defined separately for each individual object. The functionality of the basic version can be extended, if desired, with the help of additional modules, e.g. for online computation, DIN and Rainflow classification ( bin analysis ), frequency analysis and signal generation.
