HBM QuantumX - Peak Value and RMS Calculations

Real-time functions and outputs
158 A03031_24_E00_01 HBM: public QuantumX
S The peak value units do not accept other peak value units or RMS as input.
Only the 4 analog inputs are allowed.
Peak value function
Each peak value detection unit can monitor either the Min peak or the Max
peak of one of the module's 4 analog input channels. A peak value unit may
operate in different modes:
S EXPORT: peak values will be continuously updated
S HOLD: last peak value will be "frozen"
S PEAK VALUE: peak value detection enabled
S FOLLOW: peak value detection disabled, i.e. the channel returns the origi
nal signal of the input channel
The following combinations are possible:
RUN MAX PEAK VALUE
HOLD MAX PEAK VALUE
FOLLOW HOLD MAX
This also applies to minima.

Function for Root Mean Square (RMS) calculation
RMS is computed from one of the module’s 4 analog input channels according
to the formula:
