Oscilloscope Reference Operations on the time base
Operations on the time base
In general, to adjust the time base, use the front-panel horizontal Scale, Resolution, and Positions knobs.
Only channel waveforms can be set directly.
Here are some key points to remember about how horizontal operations relate to the waveform types:
Reference waveforms are shown with the horizontal settings in effect at the time that they are
saved. You cannot adjust these settings. See Saving and Recalling Waveforms
(see page 786) more
information on referenc e waveforms.
Math waveforms are shown with the horizontal settings derived from the math expression that creates
them. You cannot change these directly. See Creating
(see page 743) or Using Math Waveforms (see
page 606) for
more information on math waveforms.
All waveforms are displayed within the horizontal divisions that the graticule provides. However,
some wav
eforms may actually be wider or narrower than the display due to acquisition rate/time scale
combinations and acquisition preview.
