To set the
trigger
coupling
7. Push the up and down arrow buttons to toggle through
the possible trigger couplings:
HDC passes all (both AC and DC components) of
the input signal.
HAC passes only the AC components of an input
signal.
HHF REJ attenuates signals above 30 kHz.
HLF REJ attenuates signals below 80 kHz.
HNOISE REJ provides lower sensitivity, reducing the
chance of falsely triggering on noise.
To select the
trigger mode
8. Push the TRIGGER MODE button to toggle between
NORMAL and AUTO trigger modes:
HNORMAL trigger mode requires a trigger to acquire
a waveform.
HAUTO trigger mode acquires a waveform even if a
trigger does not occur (after a time out).
Be aware that in AUTO mode, the acquired waveforms
may not be triggered.
