1.6 Numerical Value Calculation Expressions
Numerical Calculation Type Description
Average
Obtains the average value of waveform data.
RMS (Root-Mean-Square)
value
Obtains the RMS value of waveform data. If Scaling is enabled, calculations are applied
to the waveform after scaling.
Peak-to-Peak (P-P) value
Obtains the value of the difference (peak-to-
peak value) between maximum and minimum
values of waveform data.
Maximum Value
Obtains the maximum value of waveform da-
ta.
Time to Maximum Value
(Time to Max)
Obtains the time (in seconds) from the last
trigger point to the maximum value.
If the maximum value occurs in two or more
instances, the first instance is treated as the
maximum value.
Minimum Value
Obtains the minimum value of waveform da-
ta.
Time to Minimum Value
(Time to Min)
Obtains the time (in seconds) from the last
trigger point to the minimum value.
If the minimum value occurs in two or more
instances, the first instance is treated as the
minimum value.
Period and Frequency
Displays the period (in seconds) and fre-
quency (Hz) of the signal waveform.
The calculation is based on the interval be-
tween two sequential points where the wave-
form crosses the same level (amplitude) in
the same direction (slope).
