To make automatic measurements
1 From the menu, choose Measure > Measurements....
2 In the Measurements dialog box, select the Add, Edit & Delete tab.
3 From the Type list, select the measurement you want to add.
To filter the type list, you can select the Category of measurements you want to
select from:
• All — All measurements.
• Voltage — Only voltage (vertical) measurements.
• Time — Only time (horizontal) measurements.
• Count — Only pulse or edge count measurements.
• Mixed — Measurements that consider vertical and horizontal values.
• FFT Analysis — Measurements for FFT frequency domain waveforms.
For more information on the types of measurements, see "Measurements
Summary"
on page 188.
4 In the Add Measurement area, select the Source channel, running math function,
or reference waveform being measured.
All measurements have at least one Source waveform parameter.
Only channels, math functions, or reference waveforms that are displayed are
available for measurements.
If a portion of the waveform required for a measurement is not displayed or does not display
enough resolution to make the measurement (approximately 4% of full scale), the result will
display "No Edges", "Clipped", "Low Signal" (not enough amplitude), "< value", or "> value", or
a similar message to indicate that the measurement may not be reliable.
