What is the hitchhiking of the curve?
The tracer curve is a piece of high -voltage testing equipment, which is mainly used in the laboratory to check the quality of production equipment. It exposes an electronic component either a continuous or level range of power inputs to determine the performance, efficiency or tolerance of the components. The resulting output data from the component is usually brought into the graph as a curve that gives the tool its name.
The principles and operation of the hitchhiking curve are quite simple. A test target such as a diode, transistor or switched thyristor is inserted into the machine. This step can be delicate because modern electronic components are microscopic semiconductor circuits in solid state. The machine is able to introduce accurate power, mixture of voltages and amplifiers, into the input terminal of the circuit. The output terminal of the circuit is transferred by an oscilloscope to measure the change of performance as shown in the waves of voltages and amplitude.
and Targkomponenta etned is called test devices (dut). The earliest hitchhikers toThe sequences tested the electrical circuits built in sterile vacuum tubes and displayed their output on the oscilloscope to analyze and record the operator. Modern stoppers are still displaying this, but are also equipped with computers to automate the test process and compile results.
The basic measurement of the stopper of the curve is the input voltage against the output current or V-I. The X Graph axis is the power supply of the device; The y axis is the output signatures of the dut. The conclusions that can be easily drawn from the curve include voltage leakage, measurement of the perimeter efficiency. For diodes for alternating current (DIAC) threshold values X-Y Curve clearly verify the exact voltage that triggers the status of the on-version-off diode. The hitchhiker of the curve can also reverse +/- polarity to identify defective Circuits and locate interference sources.
Components with resistor gates and components requiring the third input current can be tested similarly with all modern testme with devices. They can also display the curve in the X-Y-Z grille, but are diagnosed manually intense and require stepped voltage input control. Testable electronic components include triodes with AC switches (TriAC) and Tyristors with defended switches. Most devices can also test two circuits simultaneously, useful for performance assessment by comparing.
The different models of the test device differ depending on the maximum voltage that are capable of generating and the channel on their very small terminals. Some units are rated to 2,000 volts. High voltage and the resulting heat are safety hazards to the operators of the curves trackers. Incorporating computer interfaces into the testing device has automated processes and allows some Models operators to safely control it remotely.
