:INITiate
:INITiate:CONTinuous
:READ?
:MEASure:<function>?
Arm layer
The programmable arm events for the arm layer are described as follows:
Immediate:
Event detection occurs immediately, allowing operation to continue.
Bus:
Event detection occurs when a bus trigger (
*TRG
) is received.
External Trigger:
Event detection occurs when an input trigger is sent through the Digital IO port.
Manual:
Event detection occurs when the TRIGGER key is pressed.
