CENTER FREQ
This field is the value for the frequency located at the mid-point (center screen) of
the selected span. This frequency value may be changed by entering the digits,
decimal point, followed by the ENTER or MHz key, or the
Í and Î keys can
select a digit to increment or decrement using the SPINNER.
The range of valid entries is 0.010MHz to 1000.000MHz. Setting the Center
Frequency may change the Span field if the span must be lowered to include the
desired frequency. For example, if the Span is set to 100MHz/div and the Center
Frequency is changed to 50MHz, the span will change from 100 MHz/div to 10
MHz/div.
