How to calculate
Signal1
Plus
Signal2
(The same as signals, APS
type. Only signals with the
same EU can be calculated)
[EURMS^2+EURMS^2] =
EURMS^2
Signal1
Minus
Signal2
(The same as signals, APS
type. Only signals with the
same EU can be calculated)
Abs(EURMS^2-EURMS^2) =
EURMS^2
Signal1
Multiply
Signal2
(The same as signals, APS
type. Only signals with the
same EU can be calculated)
[EURMS^2*EURMS^2] =
(EURMS^2)
Signal1
Divided
by
Signal2
(N/A. Treat as CPS if both
signals are APS.)
[EURMS^2*EURMS^2] =
N/A
Signal
Plus
Constant
(The same as signals, APS
type)
[EURMS^2 + const^2]
Signal
Minus
Constant
(The same as signals, APS
type)
[EURMS^2 - const ^2]
Signal
Multiply
Constant
(The same as signals, APS
type)
Apply the constant to the
original data (EURMS^2)
Signal
Divided
