Meas Setup
When the Margin is selected, it may be turned off by pressing the Margin key until Off is
underlined. This may also be done by performing a preset. Margin is the default active function
whenever the margin is on, and it is not the active function whenever the margin is off.
The margin lines are displayed in the same color as limit lines, but paler. . If the limited trace is
blanked then the limit line and the margin line will be blanked as well.
Key Path Meas Setup, Limits
Remote Command :CALCulate:LLINe[1]|2|...6:MARGin <rel_ampl>
:CALCulate:LLINe[1]|2|...6:MARGin?
:CALCulate:LLINe[1]|2|...6:MARGin:STATe OFF|ON|0|1
:CALCulate:LLINe[1]|2|...6:MARGin:STATe?
Example :CALC:LLIN1:MARG –2dB sets limit line 1’s margin to –2 dB (Limit Line 1 is by default an upper
limit).
:CALC:LLIN2:MARG 1dB sets limit line 2’s margin to 1 dB (Limit Line 2 is by default a lower limit).
:CALC: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 Fail?” (:CALCulate:LLINe[1]|2|3|4|5|6:FAIL?) and “Trace Fail?”
(:CALCulate:TRACe[1]|2|3|4|5|6:FAIL?) will return 1 if the margin fails.
Couplings This will affect :CALC:LLIN3:FAIL or :CALC:TRAC2:FAIL?
Preset Not affected by Mode Preset, set to 0 dB for all Limits by Restore Mode Defaults.
State Saved Saved in instrument state.
Min –40 dB (Upper); 0 dB (Lower)
Max 0 dB (Upper); 40 dB (Lower);
Default Unit dB
Initial S/W Revision A.02.00
Edit
Opens the Table Editor for the selected limit line.
When entering the menu, the editor window (with the limit table) turns on, the selected Limit is
turned On and the amplitude scale is set to Log. The display of the trace to which the selected
limit applies is turned on (thus, traces in Blank are set to View and traces in Background are set
to On). Turning on the Limit means it’s display will be on, and it’s testing mode will be on as
well. You should turn off any other limits that are on if they interfere with the editing of the
selected limit.
