EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of DIN 44402-20 testing. In the case of AM-AM transmission, cross-modulation refers to the distortion or interference that can occur when more than one amplitude modulated (AM) signal is present in a system. This phenomenon can affect the performance of electronic tubes such as vacuum tubes or electron tubes.
To measure cross-modulation in the context of AM-AM transmission, you typically evaluate the effect of one AM signal on another. This involves generating two or more AM signals and examining the output for unwanted intermodulation products.
The measurement process may include the following steps:
Signal Generation: Generate multiple AM signals using appropriate signal generators.
Device Under Test (DUT): Connect the electronic tube under test to signal sources.
Output Analysis: Analyze the output of the electronic tube to identify any intermodulation artifacts or cross-modulation. This analysis may involve the use of spectrum analyzers or other measurement equipment.
Quantization: Quantify cross-modulation effects by measuring the amplitude and frequency characteristics of unwanted intermodulation products.
It is important to refer to specific standards such as DIN 44402-20 for detailed procedures and requirements for measuring cross-modulation in electronic tubes. Standards often provide specific guidelines and methodologies to ensure consistency and accuracy in measurements.
