Selecting the High and Low Setting: High/Low Mode
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.
• MAX-MIN
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.
Notes When Performing Automated Measurement of Waveform Parameters
• The measurement value displays “***” if the measurement is not possible (such as
when the measurement range is greater than or equal to 10 MW).
• For waveforms of small amplitude, correct measurements may not be possible.
• If there are two or more cycles of a waveform in the measurement range, the
measurement is made on the first waveform.
• Automated measurement is not possible on logic waveforms.
• If automated measurement is made on waveforms that are measured using the
realtime recording function, the execution of the automated measurement takes a
long period due to the hard disk access.
• Depending on the conditions such as the memory length, the number of measured
items, and the input waveform, the execution of the automated measurement may
take an extended period. While automated measurement is in progress,
is
indicated at the upper left corner of the screen.
• To abort the automated measurement, set Mode to OFF. The process is aborted at
that point.
• If X Axis is set to Quad in the X-Y menu, Int1XY and Int2XY cannot be measured.
• For FFT waveforms, only Max and Min can be measured.
• If the sub waveform window of the dual capture function is showing, automated
measurement of waveform parameters is performed on the sub waveform.
To perform automated measurement of waveform parameters on the main waveform,
turn OFF the sub waveform window.
• The results of automated measurements on the sub waveforms of the dual capture
function are displayed in italics.
