1.6 Numerical Value Calculation Expressions
21
Time to Level
Finds the point where the signal crosses a specified
level
from the start of the calculation range, and ob-
tains the time elapsed from the last trigger event.
Setting Choices: Level, Slope (↑ or
↓) and Filter
Pulse Width
Obtains pulse width as the time difference between
one rising or falling intersection of the waveform
through a specified level to the next intersection
(with opposite slope).
Setting Choices: Level, Slope (↑ or
↓) and Filter
Duty (%)
Obtains the duty percentage based upon the ratio of
the time from a rising intersection to the next falling
intersection at a specified level, to the time from the
same falling intersection to the next rising intersec-
tion at the same level.
Setting Choices: Level, Filter
Pulse Count
Obtains the count of pulses from the number of ris-
ing or falling intersections with a specified level.
One pulse is counted when the signal falls back be-
low the specified level after rising through it (or vice
versa)
Setting Choices: Level, Slope (↑ or
↓) and Filter
Four Arithmetic
Operations
(4 Operations)
Performs arithmetic operations (+, −, ×,÷) upon arbitrarily selected results of numerical cal-
culations.
Setting Choices: Numerical Calculation No., arithmetic operator

• Depending on the signal waveform for parameters of period, frequency, rise
time and fall time, calculated values may not be displayed.
• When Scaling is enabled, calculations are performed after waveform data has
been scaled. Also, the units of parameter values should match the scaling
units.
