µ-Lab and µ-Graph
DATA ACQUSITION AND ANALYSIS WITH 32-BIT-POWER
For the first time is able to present a software packet specially designed for comfortable data acquisition and analysis under Windows 95/98 and Windows NT - µ-Edition. The program modules µ-Lab and µ-Graph make full use of the 32-bit qualities of these operating systems and thus combine a performance previously unknown on a PC extreme ease of use.

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.

µ-Graph is a flexible, graphical analysis program for all kinds of measured data. It combines the following functions: quick-look, interactive processing, data management, presentation graphic, statistic, formula generator and, optionally, frequency analysis and bin analysis in a user interface which is particularly intuitive and easy to use. The analysis is carried out simply by dragging ( Drag & Drop ) the marked datasets onto the corresponding button in a toolbar ( e.g. print or FFT ). µ-Graph is, of course, fully compatible to the REMUS-data format.
A special highlight is the incredibly fast quick-look function, which enables the largest datasets to be displayed in a fraction of a second: simply click on the dataset name and even several megabytes of measured data appear at once on the screen without any noticable delay together with the most important statistical parameters. The quick-look has even more to offer: with the help of the mouse, any particular dataset can be marked and either printed or displayed in the interactive cursor mode. Here a wide range of functions are available, e.g. line, crosshair and difference cursor, zooming, scrolling, marking and labelling. While scrolling through long sequences of data, bookmarks can be set so that points of particular interest can easily be found again. Each dataset can be displayed in an xt-diagram, xy-diagram, bar diagram or table with manual or automatic scaling. The flexible presentation graphic in µ-Graph enables records and reports to be freely defined. Together with standard functions for drawing and labelling, the OLE interface makes it possible to include objects from other Windows programs (e.g. Excel or Word ).A report that has been designed once can be stored as a template and used again when required simply by clicking a button.
