Description
Average value
Calculates an average value of waveform data.
AVE : Average value
n
: Number of data points
di : i th data point acquired across the channel

RMS
Calculates an RMS value of waveform data. When the scaling is enabled, the instrument
scales waveform data before calculation.
RMS
: Root-mean-square value
n
: Number of data points
di : i th data point acquired across the channel

P-P
Calculates a difference (peak-to-peak
value) between the maximum and
minimum values of waveform data.

Maximum
Calculates the maximum value of
waveform data.
Maximum
Time to
maximum
Calculates a period of time (unit: s) from a
trigger point to the maximum value.
When waveform has two or more points
of the maximum value, the instrument
determines the first of them in the
waveform used for a calculation to be the
maximum value.
Maximum
Time to maximum
Minimum
Calculates the minimum value of
waveform data.
Minimum
Time to
minimum
Calculates a period of time (unit: s) from a
trigger point to the minimum value.
When waveform has two or more points
of the minimum value, the instrument
determines the first of them in the
waveform used for a calculation to be the
minimum value.

Time to minimum
Period
Frequency
Displays a period (unit: s) and frequency
(unit: Hz) of a signal waveform.
The instrument calculates a period and
frequency based on a time lag between
the time when a waveform crossed the
specified level in the positive (or negative)
direction the first time and the time when it
next crossed the specified level.
