The simple circuit shown is often called an Octopus (I don't know why), and it's been around for... Transistor Curve Tracer: 7 Steps (with Pictures) The curve tracer only sends data to the PC after it has received a command as sending data slows down the scan. It also no longer tests for the presence absence of a component. The only way to turn off the curve tracer is to send an 'O' command (or to remove the battery). A SIMPLE MANUAL CURVE TRACER Cappels A SIMPLE MANUAL CURVE TRACER Measure current vs voltage or voltage vs current over limited range with good accuracy. This was built on a phenolic board which was mounted on a plastic box. The box serves two purposes: It holds the circuit off the workbench, and it makes a nice, stable mount for the potentiometer. ... Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on . Jeff Tranter's Blog: The Octopus Curve Tracer It is a simple curve tracer, sometimes called a V I curve tracer or an Octopus curve tracer (because it has eight wires coming out of it). It is used for testing electronic components and circuitry, and works in conjunction with an oscilloscope in X Y mode (where the X and Y axes indicate the voltages on each channel and no time base is involved). Curve Tracer Schematic GroupDIY Although they do show a V I curve, the term "curve tracer" is usually reserved for a more sophisticated device that provides stepped base gate grid drive among other features. Here's somebody's marked up copy of the Heathkit IT 3121 schematic Somewhere, I have the manual for this as well as a curve tracer made by BK. Activity: A BJT Curve Tracer [Analog Devices Wiki] Build the simple curve tracer circuit shown in Figure 1. The green boxes indicate where to connect the ADALM2000.

I'm just interested in basic BJT traces but would consider anything extra. VI Curve Tracer Seattle Robotics An octopus which is another curve tracing circuit is a close relative to the V I curve tracer but is a simpler animal. It does not allow for different currents and adjustment to the voltage but it is certainly in the same family. The V I Curve Tracer is a useful tool for trouble shooting circuits down to the component level. Arduino BiCMOS Curve Tracer | Make: Make: Projects Arduino BiCMOS Curve Tracer . Make a BiCMOS curve tracer which can measure NPN, PNP, NMOS, and PMOS transistors using an Arduino, a dual Op Amp, and some resistors and capacitors. The Valve Wizard A curve tracer is like the ultimate valve tester, displaying the anode characteristic curves in real time on an oscilloscope with X Y capability (most two channel scopes have this). My first design was understandably naive in its implementation and would only test small triodes, but it worked OK (and still does).
