Note: Default values "TTL1 Pass" / "TTL2 Pass" for new traces can be set in the
"Advanced" tab of the "System Config" dialog (see "TTL Pass Default Values"
on page 707).
Remote command:
CALCulate<Chn>:LIMit:TTLout<Pt>[:STATe]
Shift Lines
By setting the "Stimulus" and "Response" values it is possible to shift a previously
defined limit line in x and y direction, respectively, without having to redefine the con-
stituent line segments.
Remote command:
CALCulate<Chn>:LIMit:CONTrol:SHIFt
CALCulate<Chn>:LIMit:UPPer:SHIFt
CALCulate<Chn>:LIMit:LOWer:SHIFt
6.6.1.2 Define Limit Lines Dialog
The "Define Limit Lines" dialog defines the limit lines for the active trace on a segment-
by-segment basis. For each segment, the limit is defined as a line connecting two
points (with linear or logarithmic "Interpolation"), or as a user-defined formula.
Access: TRACE – [LINE] > "Limit Test" > "Define Limit Line..."
Background information
Refer to Chapter 5.4.1, "Limit Check", on page 133.
When you switch to a different sweep type, existing limit lines are preserved. With a
different sweep variable, however, the limit lines cannot be displayed and the corre-
sponding limit check cannot be executed.
If you want to define limit lines for the new sweep variable, you first have to delete all
existing limit lines for the old sweep variable.
Controls on the Define Limit Lines Dialog
The "Define Limit Lines" dialog contains a table to edit the individual segments of the
limit lines. The buttons below the table extend or shorten the segment list.
