The Limit Test feature of the E5071C allows you to create up to 100 upper/lower limit lines on each trace and then determine the pass/fail status of the measured data.
When you manually configure limit lines, you must add each segment (limit line) to the limit table and define various conditions that apply to the specific segment. On the other hand, when you use an external controller to configure limit lines, you can use the following command to define all of the segment conditions (all limit lines) in the active table trace at once.
:CALC{1-36}:LIM:DATA
Alternatively, you can configure limit lines based on the data contained in a CSV file by issuing the following command:
:MMEM:LOAD:LIMAlso, you can save the contents of the current limit table to a file by issuing the following command:
:MMEM:STOR:LIM
To turn ON or OFF limit lines, use the following command:
:CALC{1-36}:LIM:DISP
Even when limit lines are hidden, the system performs a limit test if the Limit Test feature is on.
To turn ON or OFF the Limit Test feature, use the following command:
:CALC{1-36}:LIM
To turn ON or OFF the "Fail" indicator that is displayed at the center of the window when the test result for the channel is "fail," use the following command:
:DISP:FSIG
