The following are used for stimulus of the circuit under test: Power supplies; Signal generator; Digital pattern generator; Pulse generator; Voltcraft M-3850 portable multimeter. The following analyze the response of the circuit under test: Oscilloscope (Displays voltage as it changes over time) Frequency counter (Measures frequency)
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
An inrush current limiter is a device or devices combination used to limit inrush current. Passive resistive components such as resistors (with power dissipation drawback), or negative temperature coefficient (NTC) thermistors are simple options while the positive one (PTC) is used to limit max current afterward as the circuit has been operating (with cool-down time drawback on both).
It can precisely force voltage or current and simultaneously measure precise voltage and/or current. An SMU instrument can source and sink power in all four quadrants. SMUs are used for test applications requiring high accuracy, high resolution and measurement flexibility.
