The Trigger Message - HP 3314A Operating Manual

The HP-IB Group Execute Trigger (GET)
(Manual Tr igger) and pressing the MAN key cause the same action within the
3314A. In all cases the trigger source must be external (Programming Code SR2)
and the 3314A must be addressed to Listen before the 3314A will respond. The
3314A responds to the GET command within 2ms. The 3314A responds to MN
within 12ms. Triggers received when the 3314A is actively sweeping or produc-
ing ARB waveforms may take up to 50ms.
The following examples trigger the indicated devices.
