9.4 Performing Automated Measurements of Waveform Parameters on Dual Areas
Explanation
You can perform automated measurement of various measurement parameters
(waveform parameters) on the data retrieved in the acquisition memory over two areas.
You can also perform computation on the measurement parameter (waveform
parameter) values that are determined in the two areas.
Waveforms Excluded from Measurements
The following waveform measurements are not possible in the automated measurement
of waveform parameters.
• Snapshot waveforms
• Accumulated waveforms other than the newest waveform.
Automated Measurement Mode
ON: Performs computation between arbitrary items in Area1 and Area2.
Statistics: Performs statistical processing on the computed results between arbitrary
items in Area1 and Area2. See section 9.3, "Statistical Processing."
Note
Statistical processing for each period (Cycle Statistics) is not possible.
Selecting the High/Low Assignment Method: High-Low
High indicates the 100% level in measurements such as the rise or fall time. And, Low
indicates the 0% level. Select the assignment method of High and Low from the
following two methods.
• Auto
Sets the higher amplitude level to High and lower level to Low within the
measurement range based on the voltage level frequency of the waveform by taking
the effects of ringing, spikes, etc. into consideration. This method is best-suited when
measuring rectangular waveforms and pulse waveforms.
• MaxMin
Sets the maximum value to High and lowest value to Low in the measurement range.
This method is best-suited when measuring sine waveforms, ramp waveforms, etc. It
is not suited for measurement of waveforms with ringing and spikes.
Setting the Distal, Proximal, and Mesial Values: Distal/Prox
Select the method of assigning the three levels that are used as references in
measurements such as the rise and fall times.
•% (Percentage)
Set the distal value, mesial value, and proximal value using a percentage with respect
to an arbitrary trace (CH1 through CH4, Math1, and Math2 (or CH1, CH2, and Math1
for the DL1620)) with High set to 100% and Low set to 0%.
• Unit
Set the distal value, mesial value, and proximal value of an arbitrary trace (CH1
through CH4, Math1, and Math2 (or CH1, CH2, and Math1 for the DL1620)) to an
arbitrary voltage.
