Trigger slope
Press the right cursor key to set triggering at the
rising or falling edge of the input signal.
1. Triggering on the rising slope of the signal :
The screen will only display the signal when a
positive slope is "detected", viz. the signal has to rise
in vertical direction in order to trigger. (Fig 42)
2. Triggering on the falling slope of the signal:
The screen will only display the signal when a
negative slope is "detected", viz. the signal has to
drop in vertical direction in order to trigger. (Fig 43)
Notes:
•
Between triggering and the first sample-
aquisition there is a fixed hardware-determined
delay. Because of this delay, the sampled signal
can show a different slope at fast timebases.
•
When no markers are displayed, the cursorkeys
are set for changing the timebase or input
sensitivity when no keys are pressed during 10
seconds.
Changing the trigger level
Press the 'Trigger'-key to set the cursorkeys
action into 'trigger' mode.
Press up/down cursor keys to shift the Y-position
of the signal.
Notes:
•
Triggering take place at a fixed level, but by
changing the y-position of the signal you have
the effect of shifting the trigger level.
•
When no markers are displayed, the cursorkeys
are set for changing the timebase or input
sensitivity when no keys are pressed during 10
seconds.
