SCPI goes beyond the front panel controls allowing more flexible configuration options by providing complete access to the set s functionality The IEEE 488 2 standard describes how to send commands to an instrument and send responses to a controller It also defines a group of frequently used housekeeping commands to be accepted by most SCPI compliant instruments and specifies how some types of features should be implemented in SCPI firmware Although the IEEE 488 2 standard covers many aspects of communication between a controller and an instrument it does not specify which commands or features should be supported by each type of instrument Test sets from different manufacturers that conform to the IEEE 4882 standard may not be able to communicate with each other because they do not support the same command set SCPI promotes a uniform and consistent programming environment for instrument control and data usage over a IEEE 488 bus Consistency is achieved by defining the program messages instrument responses and data formats to use when communicating with SCPI instruments The Hewlett Packard Interface Bus HP IB is based on the IEEE 488 1 standard and defines the type of physical and electrical connection to use when connecting a test instrument to a controller how the devices talk and listen to each other and how a byte of data is transmitted back and forth between a controller and an instrument The HP IP cable connected betwe

Query commands instruct an instrument to retrieve the current value of the specified parameter and place it in the output buffer in preparation for transmission back to the controller The controller can then address the test instrument to Talk and retrieve the response over the IEEE 488 bus For RS 232 applications the response is not placed in the output queue Instead it is transmitted immediately to the controller over the serial link FETCR is the most commonly used query command All test results error and alarm information are retrieved using the FETCh command The test instrument also supports other query commands including SYST ERR which retrieves messages from the error queue and SYST VERS which retrieves the SCPI compatibility date Some SOURce ROUTe and SENSe commands can also be used as query commands by adding a question mark after the level 2 node and omitting the second parameter The test set returns the currently programmed value for that parameter For example the command SOUR DM OH DS2 XBIT would return the current state of the transmit DS2 X bit either 1 or 0 Note Query commands can only detect parameters that are changed using SCPI If you exit SCP mode and make changes using the front panel controls the query commands may return incorrect parameter values 1 7 Artisan Technology Group Quality Instrumentation Guaranteed 888 88 SOURCE www artisantg com Numeric Response
