Select channel
Pulses pr. cycle
Phase averaging bins width
The property Select channel is used when measurements are performed in
2- or 3-D, with the velocity channels in separate coincidence groups. In this
case 2 or 3 LDA-channels are connected yielding not only several velocity
samples, but also several arrival times.
The property Select channel determine which samples are to be phase sorted.
If you want to phase sort all the samples, you must either create a separate
cyclic object for each of them, or perform coincidence filtering first to get
samples that share common arrival times.

Reset Encoder inputs active
The property Pulses pr. cycle is relevant only when Encoder count is used
(i.e. when phase sorting is done on the basis of encoder pulses rather than
arrival time). The property indicates the length of a full cycle measured in
pulses (i.e. the number of pulses per revolution of the shaft encoder).
When a burst arrives, an encoder pulse counter in the processor is read. This
may not necessarily happen for all possible values of the encoder count.
Therefore, the software must be informed about the number of Encoder
pulses between two Reset Encoder pulses.
