There are two main types of spectrum analyzers: sweep tuning analyzers and real-time analyzers. Modern spectrum analyzers use digital signal processing to provide more measurement capabilities, making it easier for you to interpret your measurements. Whether it's a swept-tuning analyzer or a real-time spectrum analyzer, they both display the change in amplitude with frequency. But how exactly does each analyzer process and display this information? A real-time spectrum analyzer displays the energy of all frequency components simultaneously. A swept-tuned spectrum analyzer displays measurements sequentially, in other words, it does not measure in "real time". This is because a swept-tuned analyzer uses a narrow filter that is tuned over a range of frequencies to produce the spectrum display.
An oscilloscope uses a probe to connect to a test point in a circuit and amplify or attenuate the voltage at that point. The subsequent signal path depends on the oscilloscope, but in general, analog circuits condition the signal and analog-to-digital converters digitize it for further evaluation, processing, and analysis. ,
View Full VersionIts advantages include: Ultra-low jitterTrueform function/arbitrary waveform generators have jitter as low as 1 ps and excellent edge stability. You can even use them as system clocks for timing and triggering other instruments. Thanks to better jitter performance, you can locate edges more accurately, which helps reduce timing errors in circuit design. Ultra-low...
View Full VersionDigital multimeters are used, and this article will detail their advantages and disadvantages. ■ SUMMARY Electronic devices are powered by electricity. However, because electricity is invisible, it is necessary to use measuring instruments such as digital multimeters to check their safety and quality and to find out why malfunctions occur. Digital multimeters have so many buttons and ports that many people find them difficult to manipulate at first...
