10.6 Numerical Calculation Type and Description
Numerical Calculation
Type
Description
Average
Obtains the average value of waveform data.
RMS
(Root-Mean-Square)
value
(Rms)
Obtains the RMS value of waveform data. If Scaling is enabled, calculations are applied
to the waveform after scaling.
Peak-to-Peak value
(Peak-Peak)
Obtains the value of the difference (peak-to-
peak value) between maximum and mini-
mum values of waveform data.
Maximum Value
(Maximum)
Obtains the maximum value of waveform
data.
Time to Maximum
Value (Max-Time)
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
(Minimum)
Obtains the minimum value of waveform
data.
Time to Minimum
Value (Min-Time)
Obtains the time (s) from the trigger point to
the minimum value.
When there are two or more minimum val-
ue points, the first point of the first wave-
form for which calculation was carried out is
taken as the minimum value.
Period/Frequency
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.
