I have a program that uses GPIB to set limit lines on an MXA, but it does not seem to work on an EXA.
Here is a link to the X-Series Programming Guide
This guide provides Programming instructions for all X-Series Analyzers (including EXA and MXA).
Limits are documented on pages 753 to 772.
Both of the commands you listed above were found in the Programming Guide.
:CALCulate:LLINe|2|...|6:TYPE UPPer|LOWer ---> On Page 755
:CALCulate:LLINe|2|...|6:FREQuency:CMODe:RELative ON | OFF | 1 |
0 ---> On Page 758
Please review the commands you are using against the documented behavior for the commands.
If you still have trouble please send any error messages you get when sending SCPI commands to your instrument.
