NEXT MIN
RIGHT
The NEXT MIN RIGHT softkey sets the active marker/delta marker to the next
higher minimum value to the right of the current marker position on the correspond-
ing trace.
Remote command: CALC:MARK:MIN:RIGH
CALC:DELT:MIN:RIGH
NEXT MIN
LEFT
The NEXT MIN LEFT softkey sets the active marker/delta marker to the next higher
minimum value to the left of the current marker positionon the corresponding trace.
Remote command: CALC:MARK:MIN:LEFT
CALC:DELT:MIN:LEFT
SETTINGS
COUPLED
The SETTINGS COUPLED softkey couples the receiver frequency settings from the
corresponding subscans to the marker frequency for functions TUNE TO MARKER
and MARKER TRACK.
Remote command: :CALC:MARK:SCO ON
SEARCH
LIMITS
The SEARCH LIMITS softkey limits the search range for maximum or minimum
search. The softkey switches to a submenu in which the search range limits can be
set in the x and y direction.
LEFT LIMIT
RIGHT LIMIT
The LEFT LIMIT and RIGHT LIMIT softkeys define the two vertical lines F1 and F2
in the frequency domain (span > 0) and T1 / T2 in the time domain (span = 0). The
search is performed between these lines in the frequency and time domain.
If only LEFT LIMIT is enabled, line F1/T1 is the lower limit and the upper limit corre-
sponds to the stop frequency. If RIGHT LIMIT is also enabled, it determines the
upper limit.
Remote command: CALC:MARK:X:SLIM:LEFT 1MHZ
CALC:MARK:X:SLIM:RIGH 10MHZ
CALC:MARK:X:SLIM ON
THRESHOLD The THRESHOLD softkey defines the threshold line.
The threshold line represents a limit for the level range of the max. search at the
lower end and that of the min. search at the upper end.
Remote command: CALC:THR -20dBm
CALC:THR ON
SEARCH LIMIT
OFF
The SEARCH LIMIT OFF softkey disables all limits of the search range.
