Description
Enable/disable corrections that remove errors due to the window function and to
the time offset of the side lobe.
The Keep-out time specifies a region that is ignored when the trace is analyzed for
side lobes. The setting defines 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".
Specifies how measurement parameters are determined. The choices are
Absolute and Relative.
Ref specifies the level along the pulse rising edge that is defined as the point
from which Start time is counted. Choices: 50%, 60%, 70%, 80%, 90% 100%;
Default: 100%
Start specifies 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 specified by the Ref setting. Start Range: ±100 ms; Resolution:
3 digits; inc/dec small: 1 ns, large: 1,2,5,10...; Default: 0
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 specified by
Length.
In the Absolute time method, Length specifies the period of time that is used for
pulse measurements.
In the Relative time method, Length specifies 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.
Description
Specifies the period in time after the 50% rising edge at which frequency and
phase difference measurements are made.
