Hi -
You can read about limit lines by obtaining the on line PXA users and Programmer’s Guide at:
http://cp.literature.agilent.com/litweb/pdf/N9060-90027.pdf
The limit line information starts around page 366.
You can also use the built in Help text . An example of creating a simple limit line would be to press Meas Setup, Limits, and Edit. A table can be filled in with frequency and amplitude entries. To learn about the different buttons and to see the SCPI commands, at any time press Help, then the button you want to learn about and the help text will appear.
Press Cancel (esc) to exit the help screens.
