Figure 2—17 Hold off used for synchronization
of complex waveform
Operation Description
1. To select edge, trigger source and gradient shown
in TRIG MENU according to synchronization mode of
normal signal then adjust trigger level for stable
waveform display as practicable as possible.
2. To press HORI MENU key to display horizontal
menu.
3.
To adjust multi-purpose knob in upper part of
panel to alter inhibition time for stable waveform
display as practicable as possible.
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 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
