DIN 44402-17 Measurement of Electrical Properties of Electronic Tubes - Measurement Methods for Television Picture Tubes

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of DIN 44402-17 test. Television picture tubes, also known as cathode ray tubes (CRTs), are vacuum tubes used to display images in older television sets. Measurement of electrical properties is crucial to ensuring proper functionality and image quality.

Measurement of the emission properties of the cathode, which is responsible for emitting electrons when heated; This involves evaluating the cathode current and emission uniformity.

Evaluation of performance parameters of the electron gun, including focusing, convergence and astigmatism; These parameters are critical to obtain a sharp and properly aligned image on the screen.

Measurement of brightness (luminance) of the screen and evaluation of colorimetric properties; This involves ensuring that the colors displayed on the screen meet established standards.

It allows examining the geometric and linear properties of the displayed image, such as scaling the image proportionally and ensuring that it is not distorted.

It is important to note that standards such as DIN 44402-17 will provide detailed and standardized procedures for these measurements. These standards were developed to ensure that television picture tubes meet certain performance criteria and provide guidelines for manufacturers and testing facilities.
