Trigger function
Note:
•
Changing the timebase or sensitivity
switches the autorange mode off.
•
The timebase or sensitivity cannot be
changed while in hold mode.
•
At higher timebase (0,1µs and faster) the
scope uses oversampling mode, only
repetitive signals are correctly displayed.
•
Use the minimum time base (50ns) as a
starting point when measuring a signal and
select a slower time base until the signal is
displayed properly. Otherwise the display
may not correctly reflect the signal under
measurement due to aliasing.
