Product specifications

connected to EXT TRIG interface. Signal can be used waveform data automatically so as to display
for EXT and EXT can be used within signal trigger scanning base line on the screen without trigger signal
level scope of -3V to +3V. input. It will convert to trigger scanning automatically
for signal synchronization when producing trigger
signal.
Automatic trigger: The system will acquire
It is allowed to select EXT/5 for oscillograph of 5.7-
inch screen. Outer trigger shall be divided by 5 so that
trigger scope can expand to -15V to +15V for trigger
of digital storage oscillograph under large signal.
■ Municipal power: Such trigger mode can be used
to observe signal with regard to municipal power. For
instance, it can provide relationship between lighting
equipment and power supply equipment so as to gain
stable synchronization.
2 . Trigger mode: It is to determine behavior mode of
digital storage oscillograph without trigger event.
This digital storage oscillograph can also provide 3
triggers, namely, automatic, normal and single trigger
modes.

Note: Without trigger signal is allowed under “
automatic” mode when setting scanning waveform to
5-ms/div or less time base.
■ Normal trigger: Digital storage oscillograph can
not acquire waveform until meeting trigger conditions
under ordinary trigger mode. Trigger scanning can be
produced when producing trigger signal.
■ Single trigger: User can press “operation” button
once under single trigger mode for entry and trigger
waiting for digital storage oscillograph. It will sample
and display all acquired waveform then stop after
digital storage oscillograph detects once trigger.
