changes the FFT stop frequency to whatever the current value of the FFT marker frequency is, within the limitations of the available sweep times. This puts the marker on the right side of the graticule.

Front-Panel Key Access (jj)

changes the frequency at the middle of the FFT display to whatever the current value of the FFT marker frequency is, within the limitations of the available sweep times. This puts the marker in the middle of the graticule.

When using the FFT function the MARKER+ MID SCRN

softkey replaces the MARKER -+ CF softkey in the ( P E A K S E A R C H ) and @iZG] menus .

Front-Panel Key Access (j-1, (?XiGj, or

[PEAK S E A R C H )

moves the active marker to the minimum detected amplitude value.

Front-Panel Key Access (jj)

Ends and displays the frequency and amplitude differences between the highest and lowest trace points. Pressing MARKER -+PK-PK performs the routine similar to pressing

the following keys: [PEAK SEARCH), MARKER A , and

MARKER-, MIWIMUM .

Front-Panel Key Access (-1

changes the analyzer settings so that the amplitude at the active marker becomes the reference level.
