Figure 201. Edit limit for a spectrum signal
Limit configurations can be saved as data files. Press Export to save the current
limit to a data file. Press Import to load a data file to use as a limit. The
Import/Export function can save a great deal of time when similar units will be
used for different tests. The exported file will be in LIM format. The imported file
can be in format of LIM, CSV, and TXT.
Press the Scale By button to scale the limit by a factor or by the dB value defined
by users. The shape of the limit will remain the same.
The example above shows applying limit to the block signal and APS signal,
however the limit can also be applied to octave signal and FRF signal with the
same configuration.
The software allows users entering an exceeding percentage to trigger the warning
message as defined in event strings which will be displayed in the run log.
