Removing Unwanted Trigger Signal Components
0.5U
Sometimes an unwanted high-frequency or low-frequency signal component
can interfere with obtaining a stable trigger. To remove that component from
the trigger signal, move the
A
COUPL
switch to either
HF
REJ
or
LF
REJ.
The
HF
REJ
position attenuates trigger signal components above
40
kHz
and the
LF
REJ
position attenuates trigger signal components below
40
kHz.
