HThe gate width, of the input data, affects the resolution bandwidth
(RBW). Gate width has units of seconds. The resolution bandwidth
directly controls the gate width, but the numerical value is entered in
units of Hz. Therefore, the time domain gate markers move as you adjust
the RBW control.
RBW =Window Bin Width
Gate Width
Where the Window Bin Width is the resolution bandwidth in units of bins. It
depends on what window function is used. The gate width is in units of
seconds.
Figure 3--47 demonstrate the effects of adjusting center frequency and span.
Center frequency is a horizontal position control for the spectrum. Span is a
horizontal scale control. Resolution bandwidth usually adjusts the bandwidth of
the analyzer filters without affecting the span and center frequency.
