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
Transistor testers have the necessary controls and switches for making the proper voltage, current and signal settings. A meter with a calibrated "good" and "bad" scale is on the front. In addition, these transistor testers are designed to check the solid-state diodes. There are also testers for checking high transistor and rectifiers.
This is a list of the English-language television channels in Pakistan. This list contains the channels that are stationed in Pakistan by PEMRA [ 1 ] and broadcast by almost all the cable operators. List by category
India take on Pakistan in the most highly anticipated match of the ICC Cricket World Cup round-robin group stage on Saturday 8 October at the 134,000-seater Narendra Modi Stadium in Ahmedabad.
In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker ) across the chosen path.
Analog multimeter Digital multimeter. A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [2] [3] A typical multimeter can measure voltage, resistance, and current, [4] in which case can be used as a voltmeter, ohmmeter, and ammeter.
The Type 575 Transistor-Curve Tracer displays the dynamic characteristic curves of both NPN and PNP transistors on the screen of a 5-inch cathode-ray tube. Several different transistor characteristic curves may be displayed, including the collector family in the common-base and common emitter configuration. In addition to the transistor ...
A spectrum analyser – typically used as the measuring instrument in two-tone testing. Two-tone testing is a means of testing electronic components and systems, particularly radio systems, for intermodulation distortion. It consists of simultaneously injecting two sinusoidal signals of different frequencies (tones) into the component or system.
