TV (video signal): 2.0 DIV (EXT: 0.2 V)
AC coupling: Attenuate signal components < 10 Hz.
HF-REJ: Attenuate signal components > 50 kHz.
AUTO: Sweeps run in the free mode when no triggering input signal is applied.
(Applicable for repetitive signals of frequency 50 Hz or over.)
NORM: When no triggering signal is applied, the trace is in the READY state and
not displayed.
SINGLE: One-shot sweep with triggering signal. Can be reset to the READY state by
means of the RESET switch.
