Rise (10-90), Rise (20-80), Rise@Level - Transition time on the rising edge. Three selections are available
for the user to determine at which vertical level the measurement is made.
Note: Rise@Level is not available on WaveSurfer Series oscilloscopes.
Top - Value of the uppermost state in a bi-modal waveform, such as an
I

C
,
SPI
, or
CAN
Message.
Gating with Measurement Parameters
Gating is available on each standard parameter. This allows you to set a measurement window in which the
parameter should be made active. This also 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 start and stop values for the gate.
Please refer to Measure Gate in the online help for more information about Gating.
Statistics and Graphing with Measurement Parameters
Statistics and Histicons are included with nearly every LeCroy oscilloscope (Histicons are not available on
WaveSurfer Series oscilloscopes). They allow you to gather numerical and visual information on the distribution
of your various measurements.
Turn on Statistics and Histicons separately by marking their corresponding checkboxes on the Measure dialog .
Additionally, some LeCroy programs (such as JTA2) add the ability to produce larger histograms, trends, and
tracks of your measurement parameters. If you have this capability, access it through the Measurement
Parameter setup dialog (the Px tab) on the section of the dialog labeled Actions for P1.
Pass/Fail Analysis with Measurement Parameters
Set up Pass/Fail conditions by touching Analysis → Pass/Fail Setup on the menu bar.
Refer to your oscilloscope’s online help for more pass/fail setup detail.
The powerful Pass/Fail analysis using measurement parameters has a simple setup. For instance, you can define
a timing measurement, define the limits for the timing measurement, and then run the oscilloscope in a Normal
trigger mode, capturing thousands of measurement events.
What's more is Pass/Fail can then be used to save the Waveform in the event of a Fail, or send an email in the
event of a fail.
