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 ESCI 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.
Note: 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 rollkey, 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).
2nd press: The line is switched off (softkey with gray background).
Initial situation: The line is on (softkey with green background)
1st press: The data input function is activated (softkey with red background). The
position of the display line can be selected by means of the rollkey, 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).
2nd press: The line is switched off (softkey with gray background).
