Description
RMS Deviation
Subtraction of 1
cycle RMS from
adjacent cycles.
Used for cyclic
waveshape
transient trigger
system.
Maximum magnitude
value of Crest.
Largest Absolute
magnitude of
samples in a ½
cycle. Used for cyclic
waveshape transient
trigger system.
Phase of
fundamental on
individual cycle.
Derived from DFT
output based on sync
channel.
Phase of
fundamental
averaged over
200ms.
Derived from DFT sine
expansion output.
