Wagner Ground Connection: Wagner Ground Connection - When performing measurements at high frequency, stray capacitances between the various bridge elements and ground, and between the bridge arms themselves, become significant.…
Hays Bridge Circuit: Hays Bridge Circuit, shown in Fig. 11.23, differs from Maxwell's bridge by having a resistance R1 in series with a standard capacitor C1 instead of a parallel.…
Wheatstone Bridge Diagram: A Wheatstone Bridge diagram in its simplest form consists of a network of four resistance arms forming a closed circuit, with a dc source of current applied…
Transistor Tester and its characteristics: The term Transistor Tester (or analyser) used in this text is for instruments giving quantative measurements of transistor parameters. The tester should be able to…
Automatic Bridge Circuit: The bridges discussed so far require that the controls be adjusted for balance after each capacitor (or other devices being tested) is connected to the bridge. In…
LCR Bridge: Basic LCR Bridge (Skeleton Type) : A simple bridge for the measurement of resistance, capacitance and inductance may be constructed with four resistance decades in one arm, and…
Q Meter: The overall efficiency of coils and capacitors intended for RF applications is best evaluated using the Q value. The Q Meter is used to measure some electrical properties…
Vector Impedance Meter (Direct Reading): If some knowledge of the reactive and resistive factors is needed, in addition to obtaining a direct reading of the magnitude of the impedance (Z),…
