6.2.2 Long time-wave measurement (option)
The following tables indicate the maximum number of samples and time wave duration according to:
Number of simultaneous channels
Analysis frequency
There are two cases to consider:
Each point has only 1 time wave in the measurement list (1)
There is also an overall level measurement in the list (2)
Depending of the configuration, if the time wave is displayed during the acquisition, the limit can be
extended to the one of the previous case.
(1) Only one time wave measurement per channel
