R&S FSH Using Limit Lines
1309.6275.12 4.33 E-2
Operating sequence:
Press the LINES key.
The softkey menu for the control of limit lines is
displayed on the screen.
The R&S FSH makes a distinction between upper limit lines (UPPER LIMIT) and lower limit lines
(LOWER LIMIT). It checks whether a measured value is above the upper limit line or below the lower
limit line. The limit lines stored in the R&S FSH can be used to mark both upper and lower limit values.
Depending on the application, press the UPPER
LIMIT or LOWER LIMIT softkey.
The R&S FSH displays a list of available limit lines. If
no limit line is switched on, the first value in the list is
marked. If no limit lines are stored in the R&S FSH, the
cursor will be placed on folder '\Public\.'.
The unit of the limit line and the unit currently set on
the x axis must be identical. In order to determine
which lines are compatible to the current settings, the
compatible lines can be displayed:
Press softkey SORT/SHOW.
Select the item SHOW COMPATIBLE using the
rotary knob or the cursor keys and confirm the
selection with ENTER.
The R&S FSH will display only the limit lines which are
compatible to the current instrument settings.
In order to display all lines again
Press softkey SORT/SHOW.
Select the item SHOW ALL using the rotary knob or
the cursor keys and confirm the selection with
ENTER.
The file name extension indicates whether the limit lines are assigned to absolute frequency, time or
distance values (.abslim) or whether they are specified relative the center of the x axis (.rellim).
Switching on a limit line:
Select the desired limit line from the list by means of the cursor keys or the rotary knob.
Press SELECT to switch on the chosen limit line.
