* '''Accepted speed variation''': Percentage of variation of the tach speed accepted during one revolution. The default value is 100%. It means that this parameter is not taken account.

*  '''Sampling pulse''': Select an Ext. Synch input declared as "Sampling". When this setting differ from "none", the angular sampling of the SOA plug-in is based on the actual sampling pulse phase.

The angular sampling allows getting the exact angle (or phase) of the events in the machine cycle. The results are event better using the time domain averaging (i.e. angular). In order to use the angular sampling function it is necessary to have at least:

* A pulses train signal with a known number of pulses/rev
[[NVGate_Torsional#Angular_sampling_for_SOA_analysis|Please read the sampling page for more info.]]
*  phase reference (usually a 1 pulse/rev signal)

The sampling signal comes from an ext. synch input. The mode must be set to ''Sampling'' or any of the ''Sampling <nowiki>+</nowiki> xxx''
It is necessary to associate a phase reference (the 0°) to the sampling pulse. It can be any tachometer or the sampling input itself. In this last case the 0° will be the first detected pulse or the missing pulse if there are some.

Then the ''Tachometer'' and the ''Sampling'' are assigned to a SOA plug-in.

The ''Sampling pulse'' setting defines if the angular sampling is activated or not:
* If set to ''None'', the SOA will works on the regular way: Interpolation of the sampling dates from the RPM information).
* If set to a sampling input, the SOA will use it for sampling the channels signals
