LEFT
LIMIT
RIGHT
LIMIT
The LEFT LIMIT und 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 corresponds to the stop frequency. If RIGHT
LIMIT is also enabled, it determines the upper limit.
IEC/IEEE-bus commands: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.
IEC/IEEE-bus commands:CALC:THR -20dBm
CALC:THR ON
SEARCH
LIMIT OFF
The SEARCH LIMIT OFF softkey disables all limits of the
search range.
IEC/IEEE-bus commands:CALC:MARK:X:SLIM OFF
CALC:THR OFF
MKR TRACE
The MKR
→
TRACE softkey sets the active marker to a new trace. If only one
trace is available on the screen, the softkey does not appear. If several traces
are available on the screen, only these are offered.
IEC/IEEE-bus command: CALC:MARK:TRAC 2
Example:
Three traces are displayed on the screen. The marker is always on Trace 1
after switching on.
[MKR ->TRACE ] "2" <ENTER> The marker jumps to Trace 2 but remains
at the previous frequency or time.
[MKR ->TRACE] "3" <ENTER> The marker jumps to Trace 3.
