Start Frequency
Key access: [FREQ] > {Start Freq}
Sets the frequency at the left side of the graticule.
The left and right sides of the graticule correspond
to the start and stop frequencies. When these
frequencies are activated, their values are
displayed below the graticule in place of center
frequency and span.
Stop Frequency
Key access: [FREQ] > {Stop Freq}
Sets the frequency at the right side of the
graticule. The left and right sides of the graticule
correspond to the start and stop frequencies. When
these frequencies are activated, their values are

CF Step
Key access: [FREQ] > {CF Step}
Changes the step size for the center frequency
function. Once a step size has been selected and
the center frequency function is activated, the
arrow keys 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 analyzer. When
auto- coupled, the center size is set to one division
(10 percent of the span).
