Tenma 72-7630 - Pulse Trigger

13
Pulse Trigger
• Pulse trigger means determining the triggering time based on the pulse width. You
can acquire abnormal pulse by setting the pulse width condition. Adjust using the
MULTIPURPOSE control.

The system automatically samples waveform data
when there is no trigger signal input. The scan baseline
is shown on the display. When the trigger signal is
generates it automatically turns to trigger scan.
The system stops acquiring data when there is no
trigger signal. When the trigger signal is generated
trigger scan occurs.
One trigger will occur when there is an input trigger
signal. Then trigger will stop.
