Transformers are passive devices that are primarily used to convert or "transform" alternating current (AC) from one voltage level to another. One very common application of transformers is in AC to DC power supplies, in which mains voltage is stepped down before being rectified and filtered to produce DC. There are numerous other applications for transformers, such as providing electrical isolation or for impedance matching.This educational note provides a brief technical introduction to measurements made on the types of transformers used in electronics. These transformers are typically physically small, work on relatively low voltages or powers, and are used for “indoor” applications. Although many of the testing concepts described below also apply to the larger, higher-power "outdoor" transformers used for electrical power distribution, the specific tests and test procedures for these types of transformers are often specified by standards bodies such as the IEEE and may differ substantially from the types of measurements described here.Read this educational note and dive into the discussion about the six most important transformer measurements: turns ratio, mutual inductance, phase angle, primary and secondary inductance, leakage inductance, and interwinding capacitance.

Noise sources used for noise figure and gain measurements are typically controlled by the spectrum analyzer or noise figure meter instruments and are calibrated with their ENR value (Excess noise ratio). While this external control and the use of ENR values is common in noise figure test, it may be difficult in system applications where the noise source control is not available, and the use of ENR values is replaced with the values for the noise output power of the noise source. The calculation of the output power for the noise source requires to know the P_hot value (hot power) which is not a common specification for noise sources used in test and measurement applications.This application note describes a technique to perform a calibrated noise power measurement (P_hot) with spectrum analyzers and noise sources. The next sections will give further details.
