Display and Limit Lines - Analyzer
ESIB
Trace - Selecting the trace to which the limit line is assigned.
The trace is selected in an entry window. An integer entries 1, 2, 3 or 4
indicating the trace is entered. The default setting is trace 1. If the selected
limit line is not compatible with the assigned trace, the limit line is disabled.
(display and limit check).
IEC/IEEE-bus command
:CALCulate:LIMit:TRACe 1|2|3|4
Margin - Setting a margin.
The margin is defined as the level difference between the limit line and the
signal . When the limit line is defined as an upper limit, the margin means
that the level is below the limit line. When the limit line is defined as a lower
limit, the margin means that the level is above the limit line. The default
setting is 0 dB (i.e., no margin).
IEC/IEEE-bus commands
:CALCulate:LIMit:UPPer:MARGin 10DB
:CALCulate:LIMit:LOWer:MARGin 10DB
COPY
LIMIT LINE
The COPY LIMIT LINE softkey copies the data set of the marked limit line
and saves it under a new name. In this way, a new limit line can be easily
generated by parallel translation or editing of an existing limit line. The name
can be arbitrarily chosen and input via an entry window (max. of 8
characters).
IEC/IEEE-bus command
:CALCulate:LIMit:COPY 1..8|
DELETE
LIMIT LINE
The DELETE LIMIT LINE softkey erases the selected limit line. Before
deletion, a message appears requesting confirmation.
IEC/IEEE-bus command :CALCulate:LIMit:DELete
X OFFSET
The X OFFSET softkey horizontally shift a limit lines which has been
specified for relative frequencies or times (X-axis). The softkey opens an
entry window, where the value for shifting may be entered numerically or via
the roll-key.
Note: When changing the start or the stop frequency, the line on the
display only remains unchanged, if SPAN FIXED is set.
IEC/IEEE-bus command
:CALCulate:LIMit:CONT:OFFSet 100us
Y OFFSET
The Y OFFSET softkey vertically shifts a limit line, which has relative values
for the Y-axis (levels or linear units such as volt). The softkey opens an entry
window where the value for shifting may be entered numerically or via the rollkey.
IEC/IEEE-bus commands
:CALCulate:LIMit:UPP:OFFSet 3dB
:CALCulate:LIMit:LOW:OFFSet 3dB
