The tester has all these features and can check solid-state devices in and out of circuit. Transistor h fe varies fairly widely with Ic, so measurements with the service type tester give readings that can differ quite a bit from the h fe in the transistor's real life application.
In addition to the transistor characteristic curves, the Type 575 is used to display dynamic characteristics of a wide range of semiconductor devices." (Tektronix, Catalog, 1967) A curve tracer is a specialised piece of electronic test equipment used to analyze the characteristics of discrete electronic components , such as diodes , transistors ...
Creates constant-amplitude variable frequency sine waves to test frequency response Transistor tester: Tests transistors Tube tester: Tests vacuum tubes (triode, tetrode etc.) Wattmeter: Measures power in a circuit Vectorscope: Displays the phase of the colors in color TV Video signal generator: Generates video signal for testing purposes Voltmeter
On-state V CA drops to around 2 V, which is compatible with Transistor–transistor logic (TTL) and CMOS logic gates with 5 V power supply. [40] Low-voltage CMOS (e.g. 3.3 V or 1.8 V logic) requires level conversion with a resistive voltage divider , [ 40 ] or replacing the TL431 with a low-voltage alternative like the TLV431.

While not a replacement for a proper transistor tester, and most certainly not for a swept curve tracer type, this facilitates testing diodes and a variety of transistor types. [26] A graphic representation of the quantity under test, as a bar graph. This makes go/no-go testing easy, and also allows spotting of fast-moving trends.
