Using Measurement Parameters
Measurement parameters can be used to make basic timing and other measurements of your
digital or mixed-signal system. Basic parameters, such as Delay, Delta Delay, Frequency, Period,
Width, and Duty Cycle (not all parameters are available in WaveSurfer) can be used with a digital
line as a source.
Delay
–
Time from the trigger to the first transition at the 50% crossing
Delta Delay
–
Time between the 50% crossing of first transition of two
waveforms
Duty Cycle
–
Percent of time data is above 50%
Frequency
–
Frequency of every cycle in a waveform at the 50% level
and positive slope
Period
–
Period of every cycle in a waveform at the 50% level and
positive slope
Width
–
Width measured at the 50% level (can be positive or negative
slope)
Measurement Gating
Gating is available on each parameter so you can set a measurement window in which the
parameter should be activated. This allows you to eliminate unwanted portions of the acquisition
from your measurement.
Select gating from the Measure dialog by
selecting the tab for the appropriate
measurement (P1, P2, etc.) and then setting
the start and stop for the gate. Reference the
os
cilloscope’s On-Line Help for more
information on how to set gating.
