3 - Programming the DC Source

INITiate:SEQuence2 or

INITiate:NAME ACQuire

After a trigger is received and the data acquisition completes, the trigger system will return to the Idle state (unless multiple measurements are desired). Thus it will be necessary to initiate the system each time a triggered acquisition is desired.

NOTE: You cannot initiate measurement triggers continuously. Otherwise, the measurement data in the data buffer would continuously be overwritten by each triggered measurement.

Selecting the Measurement Trigger Source (Agilent 66312A, 66332A Only)

The trigger system is waiting for a trigger signal in the Initiated state. Before you generate a trigger, you must select a trigger source. The following measurement trigger sources can be selected:

BUS -	selects GPIB bus triggers.
INTernal -	selects the dc source’s output as the measurement trigger.

To select GPIB bus triggers (group execute trigger, device trigger, or *TRG command), use:

TRIGger:SEQuence2:SOURce BUS or

TRIGger:ACQuire:SOURce BUS

To select internal triggers (measurements triggered off the output signal) use:

TRIGger:SEQuence2:SOURce INTernal or

TRIGger:ACQuire:SOURce INTernal

Generating Measurement Triggers (Agilent 66312A, 66332A Only)

There is only one measurement converter in the dc source. Before you generate a measurement trigger, you must specify a measurement acquistion of either voltage or current. To specify a measurement acquisition use:

SENSe:FUNCtion "CURRent" or

SENSe:FUNCtion "VOLTage"

Providing that you have specified the appropriate trigger source and a measurement acquisition, you can generate triggers as follows:

GPIB Triggers	Send one of the following commands over the GPIB:
	TRIGger:IMMediate (not affected by the trigger source setting)
	*TRG
	a group execute trigger
Internal Triggers	To trigger off of the output signal, you must specify the output level that generates
	the trigger, the rising or falling edge of the slope, and a hysteresis to qualify trigger
	conditions. This is illustrated in figure 3-3.
