Configures the instrument’s output buffer to wait for all pending operations to complete before executing any additional commands over the interface. Triggers the instrument if TRIGger: Archived from the original on They are held in place by screws, either UTS now largely obsolete or metric M3. Return five DC voltage measurements, using a software trigger to start the measurements:. Because these operations are common to all instruments, IEEE

Retrieved from ” https: Enables 1 or disables 0 the clearing of certain enable registers at power on: Commands to control the same class of instrument, e. Status Reporting Model Back to Top 3. The physical topology can be linear or star forked. Return the instrument’s identification 48.2 This page was last edited on 2 Decemberat This register is read-only; bits are not cleared when read.

The bus line monitoring capability of an IEEE The standard also required that IEEE Event Status Enable Command and Query. SCPI was introduced as an industry standard in More information see Tektronix.


It is possible for multiple controllers to share the same bus; but only one can be the “Controller In Charge” at a time. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.

Instrument classes specify which subsystems they implement, as well as any instrument-specific features. Simple commands which start with a colon: Parameter Typical Return none none Clear event register bits and error queue: The instrument tried to read the output buffer but it was empty.

The bus employs sixteen signal lines — eight used for bi-directional data transfer, three for isee, and five for bus management — plus eight ground return lines. For example, all SCPI-compatible voltmeters, regardless of manufacturer or model, respond to the same command for reading AC voltage.

Other commands cannot be executed until this command completes. Parameter Typical Return none none Return 4888.2 DC voltage measurements, using a software trigger to start the measurements: A command syntax error occurred an error in the range has been generated.

Some commands can both set and query an instrument at once. The following table describes the Status Byte Register. Requirements of IEEE They are sometimes called “Centronics connectors” after the pin micro ribbon connector Centronics used for their printers.

The bus supports one System Controller, usually a computer, and up to 15 additional instruments. Parameter Typical Return none none Wait until all pending operations complete: PRESet resets the instrument for front-panel operation.
