Activates the center frequency function, and accesses the menu of
frequency functions. The center frequency, or start and stop frequency
values appear below the graticule on the display.
Although the analyzer allows entry of frequencies greater than the
specified frequency range, using frequencies greater than the frequency
range of the analyzer is not recommended
When changing both the center frequency and the span, change the

frequency first since the span can be limited by the frequency value.
When operating in dc coupled mode, take care to protect the input

will not necessarily represent the horizontal center of the display.
Key Access:
Sets the frequency at the left side of the graticule. The left and right
Start Freq
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.
Key Access:
Sets the frequency at the right side of the graticule. The left and right
Stop Freq
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.
Key Access:
Changes the step size for the center frequency function. Once a step

the step keys 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, the center
frequency step size is set to one division (10 percent of the span).
