limit lines will be displayed, and will affect the pass/fail status, but the trace will not
turn red if it crosses a secondary limit line.
Remote
Command
:CALCulate:DDEMod:LLINe[1]|2|…|6:WINDow <int>
:CALCulate:DDEMod:LLINe[1]|2|…|6:WINDow?
Example
:CALC:DDEMod:LLIN:WIND 1
Selects the 1
st
window as the target window that the limit line 1 will be displayed
Preset 1
State Saved Saved in instrument state
Min 1
Max 6
Margin
Selects a margin for this limit, which will cause a trace to Fail Margin when the trace
is between the limit line and the margin line. Portions of the traces which pass the
limit but fail the margin will be displayed in an amber color.
Remote
Command
:CALCulate:DDEMod:LLINe[1]|2|…|6:MARGin <real>
:CALCulate:DDEMod:LLINe[1]|2|…|6:MARGin?
:CALCulate:DDEMod:LLINe[1]|2|…|6:MARGin:STATe OFF | ON | 0 | 1
:CALCulate:DDEMod:LLINe[1]|2|…|6:MARGin:STATe?
Example
:CALC:DDEM:LLIN1:MARG 2
Sets limit line 1’s margin to 2 dB when the limit line 1’s Y axis unit is dBm or dB
:CALC:DDEM:LLIN2:MARG:STAT OFF
turns off the margin for limit line 2 and removes any tests associated with that margin line
Notes The queries “Limit Line Pass/Fail?” (:CALCulate:DDEMod:LLINe[1]|2|3|4|5|6:FAIL?)
return 1 if the margin fails
Couplings The unit of the margin depends on the limit’s Y Axis Unit. Changing the Y Axis Unit of the limit changes
its Margin’s unit, but doesn’t change its value
Preset Not affected by Mode Preset, set to 0.0 for all Limits by Restore Mode Defaults
