Setting Description
Time method Speci fi es how measurement parameters are determined. The choices are
Absolute and Relative.
Absolute time method
Ref (R) Ref speci fi es the level along the pulse rising edge that is de fi ned as the point
from which Start time is counted. Choices: 50%, 60%, 70%, 80%, 90% 100%;
Default: 100%
Start (S) Start speci fi es the time the instrument waits after the rising-edge reference before
starting to measure the pulse. The Start time is measured from the point along the
pulse rising edge speci
fi ed by the Ref setting. Start Range: ±100 ms; Resolution:
3 digits; inc/dec small: 1 ns, large: 1,2,5,10...; Default: 0
Length (L) Amount of time that should be included in the measurement. The measurement
time begins at the Start point and continues for the amount of time speci
fi ed by
Length.
Relative time method
Ref Ref speci fi es the level along the pulse rising edge that is de fi ned as the point
from which Start time is counted. Choices: 50%, 60%, 70%, 80%, 90% 100%;
Default: 100%
Start Start speci fi es the time the instrument waits after the rising-edge reference before
starting to measure the pulse. The Start time is measured from the point along the
pulse rising edge speci
fi ed by the Ref setting. Start Range: ±100 ms; Resolution:
3 digits; inc/dec small: 1 ns, large: 1,2,5,10...; Default: 0
Length In the Relative time method, Length speci fi es the percentage of the top of the pulse
that is used for measurements. The instrument automatically determines the pulse
top. The measurement length is centered within the pulse ON time.
