Boonton 9240 Series RF Voltmeter
5.5.6 INITiate and ABORt Commands
The purpose of the INITiate group of commands is to start and control the process of data acquisition once a measurement
has been configured. Depending on settings, the 9240 RF Voltmeter may be commanded to begin either a single
measurement (INITiate:CONTinuous OFF) which stops when complete, or enter a “free-run” mode where data acquisition
occurs continuously (INITiate:CONTinuous ON). The ABORt command terminates any operation in progress and prepares
the instrument for an INITiate command.
ABORt
Description: Terminates any measurement in progress and resets the state of the trigger system. Note that
ABORt will leave the measurement in a stopped condition with all current measurements cleared,
and forces INITiate:CONTinuous to OFF.
Syntax: ABORt
Argument: None
INITiate:CONTinuous
Description: Set or return the data acquisition mode for single or free-run measurements. If
INITiate:CONTinuous is set to ON, the 9240 immediately begins taking measurements. If set to
OFF, the measurement will begin as soon as the INITiate command is issued, and will stop once
the measurement criteria (averaging, filtering or sample count) has been satisfied. Note that
INITiate:IMMediate and READ commands are invalid when INITiate:CONTinuous is set to
ON; however, by convention this situation does not result in a SCPI error.
Syntax: INITiate:CONTinuous
Argument: = { 0, 1, OFF, ON }
INITiate[:IMMediate[:ALL]]
Description: Starts a single measurement cycle when INITiate:CONTinuous is set to OFF. The measurement
will complete once the voltage has been integrated for the full FILTer time. No reading will be
returned until the measurement is complete. This command is not valid when
INITiate:CONTinuous is ON, however, by convention this situation does not result in a SCPI
error.
Syntax: INITiate[:IMMediate[:ALL]]
Argument: None
Restrictions: INITiate:CONTinuous must be OFF
