Boonton 4500B RF Peak Power Analyzer
Remote Operation 5-42
5.5.7 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 4500B Peak Power Analyzer 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. In some operating modes, the INITiate commands do not actually start
measurements, but rather arm a hardware trigger, which is then used to gate the actual measurements cycle.
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, and forces INITiate:CONTinuous to
OFF.
Syntax: ABORt
Argument: None
Valid Modes: Any
INITiate:CONTinuous
Description: Set or return the data acquisition mode for single or free-run measurements. If
INITiate:CONTinuous is set to ON, the 4500B immediately begins taking measurements
(Modulated, CW and Statistical modes), or arms its trigger and takes a measurement each time a
trigger occurs (Pulse mode). If set to OFF, the measurement will begin (or be armed) 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: = {ON, OFF}
Valid Modes: Any
