Note that if you are in External Mixing, the maximum Span will be equal to the

Maximum Stop Frequency – Minimum Start Frequency for the currently selected

mixer.

CF Step

Changes the step size for the center frequency and start and stop frequency

functions. Once a step size has been selected and the center frequency function is

active, the step keys (and the UP|DOWN parameters for Center Frequency from

remote commands) change the 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 instrument.

Note that the start and stop frequencies also step by the CF Step value.

Remote Command
