INITiate Subsystem

INITiate Subsystem

The INITiate subsystem is used to control the initiation of the trigger. Refer to the TRIGger and ABORt subsystems for related commands.

Take New Data Acquisition for Selected Measurement

:INITiate:<measurement_name>

This command initiates a trigger cycle for the measurement specified. The available measurement names are described in the MEASure subsystem. It also holds off additional commands on GPIB until the acquisition is complete. So if it is followed by a FETCh command, valid data will be returned.

If your selected measurement is currently active (in the idle state) it triggers the measurement, assuming the trigger conditions are met. Then it completes one trigger cycle. Depending upon the measurement and the number of averages, there may be multiple data acquisitions, with multiple trigger events, for one full trigger cycle.

If your selected measurement is not currently active it will change to the measurement in your INIT:<meas_name> command and initiate a trigger cycle.

Example: INIT:ACP

Continuous or Single Measurements

:INITiate:CONTinuous OFFON01

:INITiate:CONTinuous?

Selects whether a trigger is continuously initiated or not. Each trigger initiates a single, complete, measurement operation.

When set to ON another trigger cycle is initiated at the completion of each measurement.

When set to OFF, the trigger system remains in the “idle” state until an INITiate[:IMMediate] command is received. On receiving the INITiate[:IMMediate] command, it will go through a single trigger/measurement cycle, and then return to the “idle” state.

Example:	INIT:CONT ON
Factory Preset:	On
*RST:	Off (recommended for remote operation)
