This page contains links to the screenshots that illustrates various features of Data Master 2003 software. See also DM2003 applications page.
|This picture demonstrates real data acquisition process: field dependence of the magnetoresistance of the carbyne sample measured at constant temperature, stabilized by temperature controller unit. Several curves recorded at slightly different temperatures are plotted on the same data window (right pane).
|Complete set of R(H) dependencies for abovementioned sample plotted in so-called "linearizing" coordinates. In this example, all curves transformed by applying X axis expression (read more about plot axis properties).
Another experiment on the same carbyne sample: temperature dependencies of DC conductivity. HTML-based data acquisition application is loaded into Browser window which is docked into main application window (left pane);
|This project contains conductivity and TEMF data for a series of quenched under high pressure carbyne samples. Sigma(T) and TEMF(T) curves may be decomposed into several contributions with the specific nonlinear fitting procedure.
Just another example of non-linear regression analysis. Magnetoresistance R(H) fitted with following expression:
All fits for R(H) series for different temperatures created by special script that uses Levenberg-Marquardt fitter exposed by DM2003 object model.
|Powerful scripting languages implemented in DM2003 allows you easily perform sophisticated numerical mathematics tasks. This screenshot demonstrates famous Lorenz attractor curve - a solution of coupled nonlinear differential equations obtained using fourth order Runge-Kutta method.
|Chaotization in the discrete nonlinear system - so-called "strange attractor". Special script creates sequence
Advanced features of DM2003 graphic engine such as axes expressions and plot label objects, allows you emulate custom plot types (polar coordinates, Smith charts, vector fields, stem plots etc) programmatically. At this screenshot you can see two curves:
|OPC stands for OLE for Process Control - a popular standard of application interface for industrial automation and SCADA software. On this screenshot, DM2003 (in the foreground) records and displays data stream provided by free Matrikon OPC Server for Simulation (see background window).
|MODBUS is an application layer messaging protocol, primarily used for communication between industrial PLCs, computers and other factory hardware. Both RS-232 and Ethernet may be used as a physical network media. In this example DM2003 is connected to the PLC simulator through TCP/IP socket.
