How To Facilitate The Observation Of Small Signals?

图片
How to set up the high sensitivity of the  Spectrum Analyzers  to facilitate the observation of small signals? A: first, set the corresponding center frequency sweep width (span) and reference level according to the size of the small signal under test;Then, the attenuation value is gradually reduced in the absence of any overload warning in the spectrum analyzer.If the SNR of the measured small signal is less than 15db, RBW will be gradually reduced. The smaller RBW is, the lower the base noise of the spectrum analyzer will be, and the higher the sensitivity will be. If the spectrum analyzer from  Spectrum Analyzer Supplier  has pre-amplifier, opening pre-amplifier and pre-release can improve the noise coefficient of the spectrum analyzer, thus improving the sensitivity. For small signals with low signal-to-noise ratio, it can reduce VBW or adopt trajectory average to smooth the noise and reduce fluctuation. It should be noted that the measurement result o...

Development of signal generator

图片
Signal generator , also known as waveform generator, is a common signal source, and is widely used in radio communication, automatic measurement and automatic control systems. The signal generator is developing towards high performance and multi breed, and the development of signal generator is embodied in the following aspects: 1, CPU function enhancement mainly displays in the computation speed and the precision enhancement aspect. 2, pin multifunction. 3, in many applications, the signal generator not only has a small size, but also requires a lower working voltage and minimal power consumption. We can also supply the  spectrum analyzer ,  universal frequency counter  etc. If you need, welcome to contact us.

How Much Do You Know About the Signal Generator?

图片
A  Arbitrary Function Generator  is an instrument that produces an electrical test signal of a desired parameter.   According to the signal waveform, it can be divided into four categories: sinusoidal signal, function (waveform) signal, pulse signal and random signal generator.   Signal generators, also known as signal sources or oscillators, have a wide range of applications in production practice and technology. Various waveform curves can be represented by trigonometric equations.   A circuit capable of generating a variety of waveforms such as a triangular wave, a sawtooth wave, a rectangular wave (including a square wave), and a sine wave is called a function signal generator. We supply  Class S Power Quality Analyzer  and Arbitrary Function Generator. If you have demand about our roducts, welcome to contact us.
