Numerical Calculation Types and Descriptions
Calculation type
Calculates the duty ratio based on the time lag
between the time when the waveform crossed
the specified level in the positive direction and
the time when it next crossed the specified
level in the opposite direction, and the time lag
between the time when the waveform crossed
the specified level in the negative direction and
the time when it next crossed the specified level
Duty ratio
in the opposite direction.

Settings: Level, Filter,
Counts the number of the pulses that crossed
the specified level in the positive (or negative)
direction.
For the pulse count, it is considered as one count
that the period between the point when a pulse
Pulse count
crossed the level in the positive direction and
the point when the pulse crossed the level in the
negative direction (otherwise, between that in the
negative direction and in the positive direction).
Settings: Level, Slope,
Performs arithmetic operations using the numerical calculation results freely selected.
Arithmetic operations
Settings:
Calculates the time lag T [unit: s] between
when Waveform A crossed the specified level
in the positive (or negative) direction and when
Waveform B crossed it in the same direction.
(Time lag T) = (Time when Waveform B crossed
Time difference
the level) − (Time when Waveform B crossed the
level)
Settings: Waveform A
Calculates the phase difference (unit: degree
[°]) with reference to Waveform A based on the
time lag between when Waveform A crossed
the specified level in the positive (or negative)
direction and when Waveform B crossed it in the
same direction.
Phase contrast
Settings: Waveform A
Calculates the low and high levels considering
0% and 100%, respectively, of the acquired
waveform data to be them based on the
High level
Low level histogram (frequency distribution).
Calculates the average of the maximum and
minimum values of the waveform data.
