Key Points
Choosing Measurements. You can perfo rm up to four automatic
measurements and display them along the right side of the graticule. All
four measurements can apply to a single channel or you can spread the
measurements over several channels. You can also take measurements
on math and reference waveforms.
First push a channel, Math, or Ref button to select the waveform
you want to measure and then select a measurement. (See page 99,
Automatic Measurements.)
Measurement Interaction with Preview. If you change a vertical or
horizontal control settin g while acquisition is stop ped or is waiting for
trigger, measu rem ents track the changes and remain valid.
Taking Gray-Scale Meas urements. Using cursors is often the best way
to take simple measurements on waveforms that contain significant
gray-scale information. The au tom atic measurements operate only on
the latest acquisition, not on the previous acquisitions that are displayed
in gray scale. However, you can set the cursors to surround and measure
thegray-scaleareaofthewaveform.
