Setting Description
Apply ampl corrections Enable/disable corrections that remove errors due to the window function and to
the time offset of the side lobe.
Keep-out time (+/-) The Keep-out time speci fi es a region that is ignored when the trace is analyzed for
side lobes. The setting de fi nes a region to the left and to the right of the center
of the main lobe. Lobes that fall within this time region are not eligible to be the
“highest side lobe”.
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 In the Absolute time method, Length speci fi es the period of time that is used for
pulse measurements.
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.

Freq Diff, Phase Diff
Setting Description
Measure point Speci fi es the period in time after the 50% rising edge at which frequency and
phase difference measurements are made.
