Electronic Four Institute successfully developed a special oscilloscope calibrator

[China Instrument Network Instrument R&D] Recently, the China Institute of Electronic Technology Standardization successfully developed the CS4801 type semiconductor tube characteristic graph meter calibrator.

The semiconductor tube characteristic plotter is a special oscilloscope that can directly observe various transistor characteristic curves and curvature clusters. Transistor characteristic plotter can be used to determine the common-collector, common-base, common-emitter input characteristics, output characteristics, conversion characteristics, α, β parameters of the transistor; various reverse saturation currents ICBO, ICEO, IEB0 can be measured And a variety of breakdown voltage BVCBO, BVCEO, BVEBO, etc.; can also determine the characteristics of diodes, regulators, SCR, tunnel diodes, field effect transistors and digital integrated circuits, a wide range of uses.

CS4801 type semiconductor tube characteristic graph calibrator (hereinafter abbreviated as CS4801) is mainly used for measuring and calibrating the main indicators of various general purpose and power type semiconductor tube characteristic plotters. It can also be used as a DC signal source. Output standard DC voltage signal from 0.1V to 1000V (1, 2, and 5 step steps) to measure X-axis voltage test system for metering characteristics of semiconductor tube; output 10μA to 10A (1, 2, 5 step) Standard DC current signal, to measure the characteristics of the semiconductor tube characteristics of the Y-axis current display system; can measure the characteristics of the semiconductor tube display instrument 1μA ~ 1A / step (10 steps) and 10mV ~ 2V / step (10 steps) step signal.

CS4801 is an intelligent graphic instrument calibrator. It realizes the computer-controlled gear selection on the basis of the original machine (formerly BJ4801A~BJ4801D), and can calculate the error and store it in the corresponding position. After the measurement of each file can be completed Measured error values ​​of each file are automatically filled in the corresponding form and can be printed and saved.

(Original Title:CS4801 Type Semiconductor Tube Characteristic Indicator Calibrator was successfully developed by our center)
