Example Scanning Using External Triggers

In the following example, the trigger input is applied to the HP

E1300A/E1301A Mainframe’s "Event In" port.

TRIG:SOUR EXT	Sets trigger source to external.
SCAN (@100:115)	Sets channel list.
INIT	Starts scanning cycle.
trigger externally	Advances scan to next channel.
Scanning Using Bus Triggers
TRIG:SOUR BUS	Sets interface (bus) triggering.
SCAN (@100:115)	Sets channel list.
INIT	Starts scanning cycle.
*TRG	Advances channel list.

:SOURce? TRIGger:SOURce? returns the current trigger source for the switchbox. Command returns either BUS, DBUS, EXT, HOLD, or IMM for trigger sources BUS, DBUS, EXTernal, HOLD, or IMMediate, respectively.

Example Query Trigger Source

TRIG:SOUR EXT	Sets trigger source to external.
TRIG:SOUR?	Query trigger source; returns
	"EXT".
