T RIG-ALT:3DIV,EXT:800mV
TV:Sync pulse more than l div(EXT:lV)
AUTO:Sweeps run in the free mode when no triggering input signal is applied.
(Applicable for repetitive signals of frequency 25Hz or over.)
NORM:When no triggering signal is applied,th e trace is in the ready state and n ot displayed.
TV-V:This setting is used when observing the entire vertical picture of tele vision signal.
TV-H:This setting i s used when observing the entire horizontal picture of television signal.
(Both TV-V and TV-H synchronize only when the synchronizing signal is ne gative)
