Period (Period)
Calculates the period of the waveform that has been assigned to Source.
Math Source Waveforms (Source)
The options are the same as were described for basic arithmetic. However, you can select an input channel of
a logic module (select the channel, and then select the bit). You cannot select the input channel of a frequency
module.
Upper and Lower Thresholds (Upper/Lower)
Set the upper and lower threshold values.
The upper and lower limits are the same as
.
Moving Average (MEAN)
Calculates the moving average according to the specified average count of the sampling data of the waveform
that has been assigned to Source.
From the start of sampling to the specified average count, average is taken up to the most recent point.
Math Source Waveforms (Source)
The options are the same as were described for basic arithmetic. However, you cannot select input channels of
frequency modules.
Average Count (Count)
Set the average count to 2, 4, 8, or 10.
RMS Value (RMS)
Calculates the RMS value of the waveform that has been assigned to Source.

s: Sampling data
N: Number of samples
Math Source Waveforms (Source)
The options are the same as were described for basic arithmetic. However, you cannot select input channels of
frequency modules.
Upper and Lower Limits (Upper/Lower)
Set the upper and lower signal limits for separating calculation periods.
The upper and lower limits are the same as
.
Unit (Unit)
You can assign a unit of up to four characters in length to the math results. The specified unit is reflected in the
scale values.
Label (Label)
You can create a label of up to eight characters in length. The labels that you create are displayed on the screen.
