Software

The SPEED Software runs with Windows operating system (W95, W98, W2000, XP etc.) One has the possibility of monochannel measurements with one SpeedMec or bichannel measurements with two SpeedMecs.

During the intake of data, real-time graphs are created of the quantities which interest the user. It's not only possible to ___ these quantities (s and v), but also to calculate at will using their values. This is especially important in the analysis phase, in which functions and curves can be fit to the graph of the data at the user's whim. In this way, hypotheses can proven or disproven by means of estimation and examination.

Example: Monochannel measurements of the Leybold Spinning Pendulum

gedämpfte Drehschwingung

In the screenshot of the program window, one can see the graphs above. Red shows the oscillation of the pendulum as a function of time. Green and blue are exponential functions, visibly lending to proof of the hypothesis:
Amplitude decays exponentially
In the bottom left one can see the control panel for channels one and two.
To the right of this is the analysis window (empty in the screenshot), in which values from the graph appear at a simple click of the mouse.
Further right is the graphing window, in which the curves to appear on the graph are displayed along with other comments.

Example: Bichannel Measurements of the Leybold Pendulum

The two pictures following are no longer screenshots, but rather graphs exported from the program. The spinning pendulum assists the more precise search of forced oscillations.

Red is the graph of the stimulus, green the oscillation. The scale is in both cases chosen equally, as one can see by the initially maximum red curve. The higher end control of the resonance and the delayed phase from about 90° is clearly recognized. resonance
no resonance
In the event that these methods of analysis aren't enough, the ability to export the measured data into a spreadsheet is also possible.

The German version of the program includes an integrated, context-dependant Help file. A full explanation of an experiment (Air-Cushion Road) is discussed, including measured data. A demo version is available (click here). The only restriction of it is the need of a new program start at every new measure.

The English version (click for demo version here) of the program is in the moment only available wirh the german help file. This will change soon.
