Answer 1

LCR meter

An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component.
The series combination of L, C, and R is known as the impedance.
It is used in radio and communication engineering and it can also be used to select a certain narrow range of frequencies from the total spectrum of ambient radio waves.
The LCR meter measures current, voltage, and phase angle and calculates the corresponding LCR values which can be represented in a number of forms.

Additional Information Cathode Ray Oscilloscope (CRO)

CRO is a device that is used for the measurement of parameters of electrical quantities like frequency, amplitude, time period, and phase difference.

Digital storage oscilloscope (DSO)

A digital storage oscilloscope (DSO) is an electronic instrument that measures and records electrical signals.
It converts the analog signal into a digital format and stores it in its digital memory.

Function generator

A function generator is a specific form of signal generator that is able to generate waveforms typically sine and square waves.
