Curve tracing is essentially a means of making a graph of current (I) versus voltage (V) called an I-V curve, to display the basic characteristics of an electronic device. I-V curves of the components are helpful in understanding their limitations and nonlinear operation.
Simple Curve Tracer Circuit for Resistor, Diode, and Transistor
In January 2021, I blew-up (through my own haste and stupid fault, I connected an incorrect external transformer) my Curve Tracer (CT) and damaged so many parts that it is difficult to get it back to where it once was. There are a number of reasons why I have decided to build a new one. Curve tracers are measurement instruments used to characterize devices such as transistors and diodes. New ones cost thousands of dollars. Even old Tektronix 575 transistor curve tracers, implemented with electron tubes and found on the surplus market, cost $75 or more. Step 1: How to Use It When you switch on the curve tracer, the main menu screen is displayed. Select the kind of device by touching one of "PNP NPN", "MOSFET" or "JFET". You can test diodes in the "PNP NPN" mode. Put the Device Under Test (DUT) into the ZIF socket. The menu screen shows you which pins to use. Building a Curve Tracer - Version 3. Mark is using Altium Designer to generate the schematics and layouts, and I had been using DipTrace, that I used for several years, to import the Altium files. This was a very cumbersome process that needed a lot of tweaks and changes. With the recent version of KiCad 6, there is now an import.
Tefa's electronics IV curve tracer
Simple but effective Transistor Curve Tracer circuit. This curve-tracer uses only 6 transistors and produces a beautiful curve display on an oscilloscope in X-Y mode. And it doesn't even matter which transistors you use to build it with!! I build it up on a bread-board first and it works very well! Simple Curve Tracer Circuit Most of electronics deals with Tracing Curves, be it the characteristic transfer curve for a feedback loop, a resistor's straight VI line or a transistor's collector voltage versus current curve. These curves give us an intuitive understanding of how a device behaves in a circuit. Sometimes called a VI curve tracer, an IV curve tracer, or an oscilloscope Octopus, this general-purpose instrument is invaluable in troubleshooting (Figure 1). The Octopus generates AC excitation across its two leads and then displays a voltage vs. current plot in real time. Attach your diode to the input connections, as described in the blinking box at the top of the screen, and press the Get Characteristic Data button. The diode characteristic will be plotted twice: on log/lin axis in the upper plot and lin/lin axis in the lower plot. The Curve Tracer will acquire and plot the diode charac-teristic.

Running the Curve Tracer. After setting up hardware and making any necessary adjustments in the calculations, press Run All at the bottom of the Wavegen 1 window, then Scan at the top of the Scope 1 window. The popped-out window, labeled "XY 1", is the I-V trace for the transistor. Note that this workspace was configured using a 2N3904 BJT. 1 7 7 Team ( 1 ) Donna LaRocco Join this project's team Video about the curve tracer completed project hardware octopus curve tracer This project was created on 01/05/2023 and last updated a year ago. Description While I have an octopus I purchased on Ebay, I really wanted to make my own with a couple bells and whistles.

Stars. 7 stars Watchers. 3 watching Forks. 5 forks Inspired by Stoneslice's tutorial, Paul Gallagher ( tardate) has developed further on the Curve Tracer by using a simple DC Powered oscillator to drive a test signal across the device under test, instead of relying on an AC power supply. Paul also added a DPDT switch to toggle and compare two devices under test.
DIY Generic Curve Tracer
The main benefit to those types of curve tracers is the fact they can make the classic stacked I_C vs. V_CE graphs that you see with all BJT (Bipolar Junction Transistor) datasheets You can also do it with this one, but you'd need to combine different scope images at various Volt/Amperage settings. 0:00 / 47:45 How To Build a Transistor Curve Tracer using the eBay CH-012 kit NFM 17.9K subscribers Subscribe Subscribed 690 Share 33K views 4 years ago Ever wanted to build your own transistor.
