Enables or disables the currently active limit line alarm. Setting the value to ON or 1 turns on the limit alarm. Setting the value to OFF or 0 turns off the limit alarm. The query version of the command returns a 1 if the currently selected limit line alarm is set to ON and returns 0 if OFF. Use :CALCulate:LIMit:TYPe to set the currently active limit line.

Shift‑6 (Limit), Limit Envelope, Lower Offset (If Limit is toggled to Lower)

Sets the number of inflection point for the currently active limit envelope. Use :CALCulate:LIMit:TYPe to set the currently active limit line. If the active limit shape is square, the number of inflection points must be even; attempting to set an odd value will result in that value being rounded down to the nearest even number.
