Using this concept the spectrum analyzer offers the functions and characteristics provided by desktop units but implements them on the small footprint of a handheld unit. For instance it offers resolution bandwidths from 1 kHz to 1 MHz in a 1-3-10 sequence. These bandwidths are designed for optimum settling in the frequency sweep with Gaussian filter characteristics. The common method of using a four-pole analog filter with decoupled contacts also yields a virtually Gaussian filter characteristic in the passband but at the expense of selectivity. Here, the shape factor of the 60 dB bandwidth to the 3 dB bandwidth would typically be
