What Is a Curve Tracer?
A curve tracer is a device used to measure semiconductors and electronic devices' current vs. voltage characteristics.
The measurement targets include resistors, diodes, transistors, and FETs. The characteristics are measured by applying a voltage to the measurement target and measuring the current flowing through the target at that time.
Measuring the current vs. voltage characteristics of semiconductors and electronic devices requires time and effort, such as continuously varying various voltages and graphing them. However, using a curve tracer makes it relatively easy to measure the current withstand voltage characteristics.
Uses of Curve Tracers
Curve tracers are used in the development of semiconductors and electronic devices, in manufacturing inspections, and in operational checks of equipment that use semiconductors and electronic devices.
If the current or voltage handled by the curve tracer is dangerous, such as when measuring at high voltages, care must be taken to use a curve tracer designed for high voltages or to apply the correct voltage setting. Also, care should be taken not to touch the part where the current is flowing directly, as there is a risk of burns or electric shock.
Principle of Curve Tracers
A curve tracer consists of a collector supply, step generator, horizontal axis circuit, vertical axis circuit, and CRT. The following is an explanation of the principle of operation, including a description of these components.
First, a step generator creates a step voltage and applies the voltage to the semiconductor or electronic device to be measured. The voltage to be measured is amplified by the horizontal axis circuit, and the horizontal axis polarizer of the CTR, a display device using a cathode-ray tube, is driven according to the amount of voltage. For the current, a collector supply rectifies the current value obtained from the measurement target into a step-like time distribution. The rectified current is amplified by the horizontal axis circuit, which drives the polarizer of the CTR according to the amount of the current, and the current is displayed on the CTR.
In addition to being output by the CTR, many curve tracers with digital specifications are also available so that the voltage vs. current characteristic values can be output to a PC or other device.
