单音的情况下CW,Video Signal 都是DC成分,所以Video Bandwidth并不会影响输出结果,但Two Tone讯号如同前面的提到的脉冲讯号,如果视频频宽VBW设定很小的时候,扫描时间够久就会剩变成一个没有变化的直流讯号,看不到双音讯号的调变行为,这直流读值也就是平均电压或平均功率Average Power。 Spectrum Analyzer实际量测Two ...

Figure 2-1 is a simplified block diagram of a superheterodyne spectrum analyzer. Heterodyne means to mix; that is, to translate frequency. And super refers to superaudio frequencies, or frequencies above the audio range. In the Figure 2-1 block diagram, we see that an input signal passes th...
Figure 1 is a simplified block diagram of the swept frequency spectrum analyzer architecture. The local voltage-controlled oscillator continuously sweeps through a range of frequencies that are combined in a mixer stage with the input signal (a process known as heterodyning)...

Learn about real-time spectrum analyzers for sound and vibration measurements also known as vibration analyzers. See how they work and how they are used.
A spectrum analyzer provided with a sync signal input terminal (27A) and a sweep control signal generator (32) inserted between the terminal (27A) and a ramp/address generator (23). When the frequency of a burst wave input signal Sx is analyzed, an external sync signal SY in synchronism ...
GW Instek's spectrum analyzer product line has three categories: application, basic and educational spectrum analyzers. These three categories are suitable for a wide range of test applications, ranging from R&D, service, maintenance, manufacturing, education and other RF-related fields. The entire ...
A spectrum analyzer which generates a frequency spectrum signal for each of a plurality of frequency bands in an input signal and displays all generated frequency spectrum signals simultaneously is disclosed. Specifically, the spectrum analyzer disclosed utilizes a mixer to heterodyne an input signal wit...
