DIN 44402-6 Measurement of Electrical Properties of Electronic Tubes and Valves - Methods for Measuring Noise Factor

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of DIN 44402-6 test. Of course, noise factor measurement is the process of determining the negative impact of an electronic device (for example, an amplifier) ​​on the signal. This measurement is usually expressed using the noise factor in dB or its equivalent, noise temperature.

Noise factor measurement usually involves these steps:

Noise Source: A noise source with a known noise level is used. This noise source usually has a certain noise temperature.

Input Signal: Apply a signal to the input of the device whose noise factor you want to measure. This generally includes the signal levels used under normal operating conditions of the device.

Output Signal: Measure the signal at the output of the device. This is a measure of any noise on the input signal and the noise added by the device.

Noise Factor Calculation: Noise factor refers to the change in signal-to-noise ratio between the output signal and the input signal. Using this ratio, you can determine the noise factor. The noise factor is usually expressed in dB.

Noise Temperature: Alternatively, you can use noise temperature instead of noise factor. In this case, you can calculate the noise factor by measuring the noise temperature and using this value.
