Your scope’s display should now look similar to
. Using the scope’s
default rising edge type trigger, we can see pulses that have various amplitudes.
The pulses that have the lower amplitudes are “runt” pulses. This particular data
stream includes both positive runts (pulses that fail to meet a minimum high level)
and negative runts (pulses that fail to meet a minimum low level). Let’s now set up
the scope to trigger on just positive runt conditions.
9
Press the
[Trigger]
front panel key and select
Runt
type triggering.
10
Tap the
Level Select
softkey to select
Low
.
11
Turn the trigger level knob to set the lower trigger level threshold to be
approximately 1 division above the bottom of the waveform.
12
Tap the
Level Select
softkey to select
High
; then turn the Trigger Level knob to
set the upper trigger level threshold to be approximately 1 division below the
top of the waveform.
