1 Introduction

3B NETlab™ is a data collection and evaluation

program for the 3B NETlog

(U11300) equipment

that can be incorporated into a network. Since it is

based on ActiveX technology, all its control ele-

ments can be integrated into web pages which can

be displayed and operated using Microsoft’s Inter-

net Explorer browser.

The main function of the 3B NETlab

program is to

facilitate computer-aided experimentation for

educational purposes. To this end, instructions for

numerous experiments from the various areas of

physics are available in web-page form. A user can

navigate between pages just as on the internet and

can use controls connected to on-site equipment to

conduct all aspects of the procedures.

display ActiveX controls on web pages. This is mostly used for integrating multimedia content (e.g. animations using Adobe's Flash Player). Since ActiveX controls can provide any kind of functionality within programs regardless of the container, this technology offers users far greater possibilities (e.g. on Microsoft’s Windows Update website, where updates can be installed into the operating system via an ActiveX control).

Windows 2000: • System control panel -> System -> Hardware -> open Device manager. • Double-click USB controller. • Double-click “ULICE USB Product”. • Click Driver -> Update driver. (The wizard for updating the device driver will start.) • Select “Show all known drivers from list and search for the suitable/appropriate driver”. • Select “Drive” and then “Search” to establish the path to the driver. • Click “Yes” to confirm that the file should be overwritten. 4.

9. A window appears in which you can select the experiments that are to be installed. These experiments have been categorised according to language and subject area. It is possible to select either individual experiments or whole categories. Select the required experiments/categories and click “OK” to confirm. 10. The experiments will now be installed. 11. After completion of the installation, a message box appears stating “Installation completed successfully. Click OK to launch program”.

• 5.1.2 Measurement functions: 5.1.2.1 Establishing and testing a connection: In the first row of the upper left hand control panel (Input control panel) in the measurement lab window, it is possible to enter the name of the connection by which the 3B NETlog™ is linked to the computer by using the “…” button. This setting need only be modified in exceptional cases. Normally, it is set to “USB”. By clicking the “Test” button, the connection can be tested and the result is displayed after a brief pause.

lected, the formula can be edited or deleted by means of the corresponding buttons. or more digital inputs (A, B), (A, B, C), (A, B, C, D) or either of the analog inputs. If the analog inputs are selected, an additional check box appears for setting a comparator threshold (see below). • Input range: Digital inputs: assigns logical states to physical input signals. “Uninterrupted = 1” means that high voltage (>3.8 V) at the input corresponds to a logical 1 and low voltage at the input (<0.

• • • Data”. If you click the latter, the measurements most recently recorded (128 samples) remain displayed in the display mode selected at the top, just as in standard mode, and are available for evaluation. Activate the inputs which are to be triggered at the left of the box. In the middle of the box you can select whether the trigger should occur when the signal crosses the threshold rising or falling.

generator can be set in the corresponding input box of the “Sampling” panel. Next to this is the check box “Generator enabled” that enables the function generator. The type of signal can be defined separately for Channel A and Channel B by selecting the corresponding output. Clicking “Predefined” opens a dialog box in which one of the following predefined signal waveforms can be selected: “Sine”, “Rectangle”, “Triangle” and “Flat”. The parameters are also modified according to the selected type of signal.

function with the specified parameters in the preview. • In addition to the input fields for the initial values, activating the check box can cause the parameter values to remain constant during the fitting of the function. • Click “Try to fit”. The result is displayed in the preview. The correlation coefficient R2 is output above the control panel labelled “Parameters”. • After clicking “OK” and exiting the window for fitting the function, the fit function is also plotted on the graph.

• ment at their own computer while students observe at their terminals. Communication is conducted entirely via Windows file sharing. No additional TCP connections need to be set up. The supervisor can regularly access and read a data file shared by the computer where the experiment is being conducted. The data is thus accessible from the supervisors’ controls after only a very brief delay.

• • • Go to “Administration”. Select “Administrate the teachers' list” and click “Continue”. Select “Create a new teacher entry” and click “Continue”. Enter a user name and password, click “OK” to confirm. 6.3.2 Changing your own password: Any teacher can only change his/her own password. • Go to “Administration”. Select “Administrate the teachers' list” and click “Continue”. • Select “Edit current teacher entry” and click “Continue”. • Activate the “Change” check box in the field labelled “Password”.
