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.
