19.2.2 Maths Equations Processes
The Maths Equation builder supports a number of processes which act on the full array of samples.

Transfers the samples to the output channel.
Integrates the samples with respect to time.
Differentiates the samples with respect to time.
X:n – Filters the samples X using Filter n. n can be a constant or an expression. Use Set Filter
n to set the Filter n characteristic.
Derives the instantaneous frequency. Uses a Gabor filter active over 1024 samples to
determine the mean frequency at the current sample point. Will not work if there is not at
least a partial waveform transition within the 1024 samples. If you are using full buffer
maths, a low frequency signal will not work because there are >> 1024 samples per period.
Returns 1 if any samples are >0, otherwise returns 0.
Returns DC value of the samples.
Returns Average value of the samples.
Returns Standard Deviation of the samples.
RMS
Pk-Pk
Minimum
Maximum
Freq (Amax)
Amax (Fo)
Phase (Fo)
Returns RMS value of the samples.
Returns Peak to Peak value of the samples.
Returns Minimum value of the samples.
Returns Maximum value of the samples.
Returns the Frequency of the highest amplitude frequency component (Fo)
Returns the RMS amplitude of the frequency component Fo.
Returns the starting phase of frequency component Fo.
Period
Duty Cycle
Pulse Width
Undershoot
Overshoot
Slew Rate
X:Y Pwr Factor
X:Y Phase
Returns the period of the signal in samples. You need at least one cycle.
Returns the duty cycle of the signal in samples. You need at least one cycle.
Returns the hi pulse width of the signal in samples. You need at least one cycle.
Returns the undershoot of the signal in samples. You need at least one cycle.
Returns the overshoot of the signal in samples. You need at least one cycle.
Returns the slew rate of the signal in samples. You need at least one cycle.
Returns the ratio of the real power/apparent power (VA) assuming X is current and Y is
voltage.
Returns the Phase, in degrees, between X and Y. If +ve, X leads Y.
