Term explanations

1. Trigger source: To gain trigger from many kinds of
information sources, namely, input channel (CH1 &
CH2), external trigger (EXT & EXT/5) and municipal
power.
Input channel The most common trigger
Holdoff
information source is
Selected one is used as channel of trigger
information source for normal operation regardless
of input display
External trigger: Such trigger information source
can be used for trigger on the third information
channel during synchronous data acquisition on
channels For instance signals from external clock
or circuit to
measure can be used as trigger information source.
EXT and EXT/5 trigger sources shall use external
trigger signals
optional input channel
