What Is A Bulk Current Injection: High current injection is a testing technique in automotive electronics used to verify whether a product will experience functional degradation or exceed tolerance limits when subjected to electromagnetic interference of different frequency ranges. This test is commonly encountered in EMC testing for automotive electronics, as in actual vehicle scenarios, the connecting cables for different onboard components are often bundled together. This leads to the coupling of electromagnetic interference signals of different frequencies, which in extreme cases, can result in failure of the affected components, posing a risk to the safety of the vehicle. Hence, the purpose of high current injection testing is to simulate the injection of RF signals onto the power or signal lines of the product being tested in order to verify whether its function will degrade or its performance indicators will remain within tolerance limits. High current injection testing is a com...

The spectrophotometer uses the grating spectrophotometer principle for color measurement. A grating is an optical element that is engraved with a set of parallel periodic lines or grooves (often inclined) on a plane. When a beam of compound light is incident on the grating plane, its periodic structure will undergo diffraction, and the transmitted or reflected diffraction light will also interfere. The energy of the light will be redistributed, and different wavelengths of light will travel in different directions, forming a specific wavelength superposition extremum at a certain position, thereby achieving light splitting. Spectroscopic colorimeters can produce spectral curves, which are equivalent to a color’s ID card and are unique. Therefore, the color data read by the spectrophotometer is absolutely accurate. The role of spectrophotometer in colorimetry: The chemical industries such as textiles, printing and dyeing, petroleum, and batteries often generate a lot of industrial waste...

A spectrophotometer is an instrument used to measure the reflected spectral power and light characteristics of objects to determine their standard color values. However, measurement results can vary due to differences in color difference calculation methods and light source selection. Therefore, it is crucial to carefully select appropriate color difference formulas and light sources when using a spectrophotometer. A spectrophotometer is typically used to measure color characteristics and reflectance of objects, providing various numerical values to describe the color and color difference of objects. Here are the values that a spectrophotometer can generally measure: • Tristimulus Values: Measures the reflected light intensity of objects at different wavelengths, calculating the RGB tristimulus values perceived by the human eye. • Chromaticity Coordinates: Computes chromaticity coordinates based on measured tristimulus values, often represented as xyY or Lab coordinates. These coordi...
