WebMar 2, 2015 · Normally I use a VBW at least with a 2:1 VBW/RBW ratio unless i am measuring continuous signals. But, just to experiment i lowered the VBW below RBW and -as expected- the transient peaks vanished slowly. So, looking at the above pictures, the "peaks" at the burst edges are exactly what is meant by the "transient effects".

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. how to do a cover letter uk
