WebMay 25, 2015 · Selecting lower RBW directly reduces the noise floor, and makes CW signals easier to see; unfortunately, many cellular communication signals are also noise-like and do not benefit from reduced RBW. Selecting lower VBW smoothes both the noise and noise-like signals, and can make it easier to see signals near the noise. WebConnect a 28V DC supply voltage to the noise head. We can monitor the output noise density on a spectrum analyzer. By Turning off then turning on the DC power supply, the noise density increased from -90dBm/Hz to -87dBm/Hz. So Y = 3dB. Again to get a stable and accurate reading of the noise density, RBW/VBW is set to 0.3.
