Alternating current

Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction.

Bridge circuit

A bridge circuit is a topology of electrical circuitry in which two circuit branches (usually in parallel with each other) are "bridged" by a third branch connected between the first two branches at some intermediate point along them.

Capacitance

Capacitance is the ratio of the change in an electric charge in a system to the corresponding change in its electric potential.

Device under test

A device under test (DUT), also known as equipment under test (EUT) and unit under test (UUT), is a manufactured product undergoing testing, either at first manufacture or later during its life cycle as part of ongoing functional testing and calibration checks.

Electrical resistance and conductance

The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor.

Electronic component

An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields.

Electronic test equipment

Electronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs).

Equivalent series resistance

Practical capacitors and inductors as used in electric circuits are not ideal components with only capacitance or inductance.

ESR meter

An ESR meter is a two-terminal electronic measuring instrument designed and used primarily to measure the equivalent series resistance (ESR) of real capacitors; usually without the need to disconnect the capacitor from the circuit it is connected to.

General Radio

General Radio Company (later, GenRad) was a broad-line manufacturer of electronic test equipment.

Inductance

In electromagnetism and electronics, inductance is the property of an electrical conductor by which a change in electric current through it induces an electromotive force (voltage) in the conductor.

Phase angle

In the context of phasors, phase angle refers to the angular component of the complex number representation of the function.

Q factor

In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is, and characterizes a resonator's bandwidth relative to its centre frequency.

Q meter

A Q meter is a piece of equipment used in the testing of radio frequency circuits.

Voltage

Voltage, electric potential difference, electric pressure or electric tension (formally denoted or, but more often simply as V or U, for instance in the context of Ohm's or Kirchhoff's circuit laws) is the difference in electric potential between two points.

Voltage source

A voltage source is a two-terminal device which can maintain a fixed voltage.
