SAVE LIMIT
LINE
Basic Settings
In this manner, a new limit line can be easily generated based upon an existing limit
line which has been shifted vertically and stored (SAVE LIMIT LINE softkey) under a
new name (NAME softkey).
Remote command: CALC:LIM3:CONT:UPP:SHIF 20dB
CALC:LIM3:CONT:LOW:SHIF 20dB
The SAVE LIMIT LINE softkey stores the currently edited limit line. The name can be
entered in an input window (max. 8 characters)
Remote command: --
4.6.1.3 Display Lines
Display lines help to evaluate a trace – as do markers. The function of a display line
is comparable to that of a ruler that can be shifted on the trace in order to mark
absolute values.
The R&S FSQ provides two different types of display lines:
• two horizontal level lines for marking levels – Display Line 1/2,
• two vertical frequency or time lines for marking frequencies or points in time –
Frequency/Time Line 1/2.
Each line is identified by one of the following abbreviations:
D1 Display Line 1
D2 Display Line 2
F1 Frequency Line 1
F2 Frequency Line 2
T1 Time Line 1
T2 Time Line 2
The level lines are continuous horizontal lines across the entire width of a diagram
and can be shifted in y direction.
The frequency or time lines are continuous vertical lines across the entire height of
the diagram and can be shifted in x direction.
The DISPLAY LINES submenu for activating and setting the display lines appears
different depending on the display mode set in the active measurement window (frequency
or time domain).
If the spectrum is shown (span ≠ 0) the TIME LINE 1 and TIME LINE 2 softkeys are
disabled, whereas in the time domain (span = 0) the FREQUENCY LINE 1 and
FREQUENCY LINE 2 softkeys are not available.
Working with display lines
The softkeys for setting and switching the display lines on/off work like triple
switches:
Initial situation: The line is off (softkey with gray background)
1st press: The line is switched on (softkey with red background) and the data input
function is activated. The position of the display line can be selected by means of
the rotary knob, the step keys or a numerical entry in the appropriate field. The data
input function is disabled if another function is activated. The line, however, remains
switched on (softkey with green background).
