DATA Entry
Example
Surveillance of a wide frequency span sometimes requires high resolution. One fast way to achieve this is to take
the span in sequential pieces using a tailored center frequency step. This example looks from 0 Hz to 2.5 GHz in
50 MHz spans.
First set the span and center frequency: For a span of

Changes the step size in display unit increments.
Changes the step size in steps equal to one-tenth of the frequency span.
Selects a specific step size to a resolution equal to the current center fre-
quency readout.
