Oscilloscope as a curve tracer

Electronic components are characterized by their unique characteristics. We developed a device that makes visible, in conjunction with a simple oscilloscope such characteristics.

This device allows the characteristics of electronic components to 60 V and 3.6 W are shown on the oscilloscope. This area includes almost all modern electronic components a (transistors, thyristors. Triacs, diacs. FETs, resistors, diodes. Zener diodes, VDR, NTC and PTC resistors, photo diodes, photo resistors, etc.). This plant is not suitable for tubing, but which are found only in very specific applications.

The characteristic of a component is a graphical representation from which one can refer to each voltage value associated with the current value. Thus the behavior of an electronic component is defined.


The curve is the "fingerprint" of a component

The measurement is done by the tension gradually increased and readings for each voltage value associated power value and enters the measuring point in a current-voltage diagram. Finally, one connects the individual measuring points, giving it the characteristic of the electronic object that can be so clearly characterized and evaluated.

These measurement procedures are realized in this simple circuit construction. Shown are the curves on an oscilloscope, which is on the X and Y inputs connected to the circuit.

Again all the circuit specifications on prototyping board with copper lacquer wire to connect the components themselves. The rest were connected with insulated wire circuit.
