2.7.4 CF Step
Changes the step size for the center frequency and start/stop frequency functions. Once a
step size has been selected and the center frequency function is activated, the step keys
(and the UP|DOWN parameters for Center Frequency from remote commands) change
center frequency by the step-size value. The step size function is useful for finding
harmonics and sidebands beyond the current frequency span of the analyzer. When
auto-coupled in a non-zero span, the center frequency step size is set to 10% of the span.

Range:
if Span = 0 Hz increment = RBW/20
if Span > 0 Hz increment = Span/200
if CF Step = auto, Span = 0 Hz step = RBW
if CF Step = auto, Span > 0 Hz step = Span/10
if CF Step = manual step = 1, 2, 5 sequence
