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
information source is optional input channel
Selected one is used as channel of trigger
information source for normal operation regardless
of input displa

External trigger: Such trigger information source
can be used for trigger on the third informatio
n
channel during synchronous data acquisition o
