WebThe resolution bandwidth control selects which RBW filter is used. The shape of a spectrum displayed on the analyser screen is a combination of the shape of the RBW filter and the shape of the true signal spectrum. The figure-1 depicts filters used for RBW and VBW … Webstep is 1 / k of RBW, to ensure the accuracy of amplitude measurement. The second factor means that each selection The time required depends on the smaller value between RBW …
Emulating Video Bandwidth and Detectors in an FFT-based Vector Signal
WebSWEEP-TIME is proportional to SPAN and inversely proportional to both RBW and VBW. The VBW is, by default, equal to RBW and cannot exceed it. Figure 5 shows the effect of reducing the RBW on the displayed graphs (RBW = VBW). Figure 5 Smoothing displays: (for Swept-LO SA) [3, Chapter 2] Smoothing is accomplished in two ways: a. Reduce the VBW ... WebMay 8, 2013 · The sweep time, RBW and VBW are auto in this measurement. It seems that VBW and RBW is 3 kHz. Only the options: RBW:Span and VBW:RBW are off. Are you saying to tyrn on VBW:RBW and set it like 0.01. What does it mean? As the measuremnt given is SSB, I dont understand why there is also spectrum in the left side of the peak. garnet street saltburn by the sea

Hi, I'm a using a N9000A CXA spectrum analyzer, which has the capability of producing spectral … WebA wider RBW makes two signals appear as one signal and difficult to distinguish them. VBW is the low pass filter, which helps smooth out the signal. It is also possible to do video averaging on our spectrum analyzer to improve resolution of weak signals in … black sabbath iced earth
