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.
CHANGE THE TRIGGER CHANNEL
• Press the 'TRIGGER'-key to set the cursor-
keys action into 'trigger' mode.
• Use the ▲or ▼arrow buttons to select the
trigger channel.
Note:
The location of the trigger mode text and/or
the trigger position indicate(s) the channel
being used to trigger (fig. 48 to 53).
