ZVA/ZVB/ZVT Trace Menu
1145.1084.12 4.115 E-6
The dialog assigns common properties to all limit line segments generated by the imported trace.
• Offsets contains two input fields to define constant offset values for all imported segments. The
Response offset shifts all segments in vertical direction, the Stimulus offset shifts them in
horizontal direction. The offsets are added to the start and stop values of all segments.
• Type defines whether the imported segments belong to the Upper or Lower limit line. A third
option is to import the segments but disable the limit check (Off).
Remote
control:
CALCulate<Ch/Tr>:LIMit:LOWer:FEED
<stimulus_offset>,<response_offset>[,<trace_name>]
CALCulate<Ch/Tr>:LIMit:UPPer:FEED
<stimulus_offset>,<response_offset>[,<trace_name>]
File Format for Limit Lines
The analyzer uses a simple ASCII format to export limit line data. By default, the limit line file has the
extension *.limit and is stored in the directory shown in the Export Limit Line and Import Limit Line
dialogs. The file starts with a preamble containing the channel and trace name and the header of the
segment list. The following lines contain the entries of all editable columns of the list.
Example of a limit line file
