Time to level
Searches a calculation range from the beginning
for the time when a signal crossed the specified
level and calculates a period of time from a
trigger point to a point searched for.
Settings: Level , Slope , Filter
0 V
Level
Level at time
Calculates a level when the specified time has
elapsed from a trigger point.
You can also specify a time based on previously
calculated results.
Settings: Method ( Time , Calc. No. ), Time/
calculation number ( No. 1 to No.107 )
0 V
Level
T (Time)
Pulse width
Calculates a pulse width based on a time lag
between the time when a waveform crossed
the specified level in the positive (or negative)
direction and the time when it next crossed the
specified level in the opposite direction.
Settings: Level , Slope , Filter , Stat.
Level
Duty ratio
Calculates a duty ratio based on a time lag
between the time when a waveform crossed the
specified level in the positive direction and the
time when it next crossed the specified level in
the opposite direction, and a 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 in
the opposite direction.
