Making Automatic Measurements
[Meas] makes automatic measurements on a channel or any running math
function. Some measurements can only be made on analog source channels
(see list on page 157). The results of the last four selected measurements
are displayed above the softkeys, or in the display area when certain
menus are selected. [Meas] also makes measurements on stopped
waveforms when you are panning and zooming.
Cursors are turned on to show the portion of the waveform being
measured for the most recently selected measurement (right- most on the
measurement line).
1 Press the [Meas] key to display the Measurement Menu.
2 Press the Source softkey to select the channel or running math function
to be measured.
Only channels or math functions that are displayed are available for
measurements. If you choose an invalid source channel for a
measurement, the measurement will default to the nearest in the list
that makes the source valid.
If a portion of the waveform required for a measurement is not
displayed or does not display enough resolution to make the
measurement, the result will display “No Edges”, “Clipped”, “Low
Signal”, “< value”, or “> value”, or a similar message to indicate that the
measurement may not be reliable.
