INITiate

 

The INITiate command subsystem places the multimeter in the wait-for-trigger state.

 

This command is most commonly used with CONFigure. See the section titled

 

“Triggering the Multimeter” beginning on page 45 for a complete description of the

 

HP E1312A and HP E1412 trigger system which discusses the wait-for-trigger state.

Subsystem Syntax

INITiate

 

[:IMMediate]

[:IMMediate]

INITiate[:IMMediate] places the multimeter in the wait-for-trigger state. When a trigger is received, readings are placed in multimeter internal memory.

Comments • After the trigger system is initiated using INITiate, use the TRIGger command

subsystem to control the behavior of the trigger system.

•If TRIGger:SOURce is IMMediate, the measurement starts and readings are stored in internal memory as soon as INITiate is executed. Readings stored in memory from previous commands are replaced by the new readings.

•To transfer readings from memory to the output buffer, use the FETCh? command.

•If TRIGger:SOURce is not IMMediate, the measurement starts as soon as a trigger is received either from the external BNC connector, the VXIbus backplane (TTLT<n> trigger lines) or a BUS trigger.

•The READ? command executes INITiate implicitly. The MEASure command executes READ? implicitly. Executing READ? outputs data directly to the output buffer, bypassing the multimeter’s internal memory.

•Related Commands: CONFigure, FETCh?, READ?

•*RST Condition: *RST places the multimeter in the idle state.Example Placing Multimeter in Wait-For-Trigger State
