WebApr 25, 2016 · My fancy Advantest SA can go to a RBW of 1 KHz. The DSA815 is much better, with a low-end setting of 100 Hz. Pretty slick! “k” in the above formula is an SA-dependent constant. I found that with a 1 MHz span, and RBW = VBW = 1 KHz, the sweep took 3.3 seconds, compared with one second for the much more expensive Advantest. WebFeb 1, 2024 · Resolution Bandwidth (RBW) The resolution bandwidth (RBW) determines the FFT bin size or the smallest frequency that can be resolved. For a traditional swept-tuned (non-digital) spectrum analyzer, the resolution bandwidth is the bandwidth of the IF filter which determines the selectivity.
