Description
Time method
Speci
fi
es how the measurement’s duration is 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)
Length speci
fi
es the period of time that is used for pulse measurements The
measurement time begins at the Start point and continues for the amount of time
speci
fi
ed by Length.
Relative time method
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.
