Simple Curve Tracer Circuit for Resistor, Diode, and Transistor

The output of the curve tracer can be read o of two test points and an oscilloscope in X-Y mode can be used to display the curves generated. This allows for the easy export of the characteristic curves through the oscilloscope's USB port. 2 Project Overview Our project's circuit can be split into three main parts - the device identi cation.

[VERTICAL DEFL.] The 3rd transformer is used to generate an impulse to trigger the counter (74HC191) which counts from 0 to 7. The output of this counter forms with an R2R-network a staircase which is amplified to 7 Vpp. (adjusted with R20). This staircase is inverted with IC6a and another relais switches between the polarity (NPN or PNP).

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.

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.

The curve tracer testing is a diagnostic tool used to measure the electrical performance of an electrical system. It measures inductance, resistance, and capacitance by measuring voltage and current in response to a range of test inputs. The curve tracer is a testing device that measures the performance of cables and wires about the three.

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.

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.

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.

A Simple Curve Tracer

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.

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.


Curve Tracer Schematic

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.
