A1500 SERIES resume output.

TTL signal changes to high. User must press to resume output and enable TTL signal

• EXCITE：When user is using LIST, PULSE or STEP modes, output ON/OFF of A1500
SERIES can be triggered by rising edge of TTL signal (LOW
(please refer to 3.8.2~3.8.4 for trigger page). The pulse signal must keep at least 1ms
when the signal changes.
■ When output of AC source is at off state, it will be triggered to on state if TTL
signalchanges from LOW → HIGH. There will be two conditions introduced as below.
◆ If output sequences finishes and TTL signal changes from LOW → HIGH again, the
output will be triggered to on state and repeat the sequences again.
