Note:
Changing the timebase or sensitivity switches
•
the autorange mode immediately off. (Fig 42)
The timebase or sensitivity cannot be changed
•
into hold mode.
Pressing the 't-V/div' key into hold mode
•
toggles the screen between the two stored
waveforms.
At higher timebase (1µs and faster) the scope
•
uses oversampling mode, only repetitive
signals are correctly displayed.
Use the minimum time base (250ns) as a
•
starting point when measuring a signal and
select longer time bases until the signal is
displayed properly. Otherwise the display
may not correctly reflect the signal under
measurement due to aliasing.
THE TRIGGER SETUP
