Measurement & Analysis Instruments
Spectrum analyzer is a more suitable instrument for measuring EMI. Spectrum analyzer is the instrument displaying voltage amplitude change with the frequency and its waveform called spectrum. Spectrum analyzer overcomes the shortcomings of oscilloscope in measuring EMI and it can accurately measure the EMI at each frequency and directly display the signal spectrum components.
Nearby probe includes: EMI electric field probe and EMI magnetic field probe.

Set spectrum analyzer's sweep range and analyzing bandwidth according to the interference frequency.
The corresponding relationship between sweep range and analyzing bandwidth are as follows:
To set the Spectrum analyzer's sweep range, you need press【FREQ】firstly and then set Starting frequency and Stop frequency.
To set the analyzing bandwidth, you need to press【BW】firstly, and then input the needed bandwidth which should be within the range of this instrument.

yro sensors are an essential component in many electronic devices, including smartphones, gaming controllers, and drones. However, like all electronic components, gyro sensors require calibration and maintenance to ensure optimal performance and longevity. In this article, we will explore some tips and best practices for calibrating and maintaining gyro sensors in your devices.
Lenses are a vital component of optics and are widely used in various fields, including astronomy, medicine, photography, and microscopy. A biconcave lens, also known as a concave lens or a diverging lens, is one of the most common types of lenses used in scientific and industrial applications. In this article, we will explore the properties, uses, and applications of the biconcave lens.
Meniscus lenses are a type of optical lens that has a convex surface on one side and a concave surface on the other. They are commonly used in a wide range of applications, from cameras and microscopes to lasers and telescopes. In this article, we will explore the applications and advantages of meniscus lenses.
The Micro Motion Coriolis Meter is a flow metering device that has become increasingly popular in various industrial applications. It operates on the principle of the Coriolis effect, which is a physical phenomenon where an object in motion experiences a force perpendicular to its direction of movement when observed from a rotating frame of reference.
Fused silica is a highly pure, synthetic amorphous silicon dioxide (SiO2) material that is made by melting high-purity silica sand. It is an extremely hard and chemically resistant material that is used in a variety of applications, including the production of laboratory equipment, optical fibers, and semiconductor wafers.
