IEEE 488.2 DRIVER

An execution error occurred an error in the range has been generated. This page was last edited on 26 July , at Some commands can be used for both setting and querying an instrument. Mechanical considerations limit the number of stacked connectors to four or fewer, although a workaround involving physically supporting the connectors may be able to get around this. Control and data transfer functions are logically separated; a controller can address one device as a “talker” and one or more devices as “listeners” without having to participate in the data transfer. The bus employs sixteen signal lines — eight used for bi-directional data transfer, three for handshake, and five for bus management — plus eight ground return lines. Requirements of IEEE

The data transfer is relatively slow, so transmission line issues such as impedance matching and line termination are ignored. The bus employs sixteen signal lines — eight used for bi-directional data transfer, three for handshake, and five for bus management — plus eight ground return lines.

eiee Return the installed options: For octal, the letter ” Q ” was chosen instead of the letter ” O ” to minimize the visual confusion with the number ” 0 ” zero. The slowest participating device determines the speed of the bus. Read Status Byte Query.

It is possible for multiple controllers to share the same bus; but only one can be the “Controller In Charge” at a time.

Following the test, the instrument returns to the instrument state that existed before the self-test. The bus line monitoring capability of an IEEE Because of these IEEE If the application program can jump to this protocol immediately upon the assertion of the SRQ line, you increase program efficiency and throughput. Parameter Typical Return none none Return five DC voltage measurements, using a software trigger to start the measurements: Some parameters can be set with either [SENSe: Wait until all pending operations complete: While physically large and sturdy connectors were an advantage in industrial or laboratory set ups, the size and cost of the connectors was a liability in applications such as personal computers.

The multi-conductor parallel data connectors and shielded cable were inherently more costly than the connectors and cabling that could be used with serial data transfer standards such as RSRSUSB, FireWire or Ethernet.

Parameter Typical Return none 1 Configure 48.82 voltage measurements and return “1” when the measurements complete: Any or all conditions can be reported to the Standard Event summary bit through the enable register.

Devices from different manufacturers might use different commands for the same function. Archived from the original on 48.82 Parameter Typical Return none see below Return the installed options: Status Reporting Model Back to Top 3. Parameter Typical Return none none Wait until all pending operations complete: Parameter Typical Return none see below Return the instrument’s identification string: SCPI was introduced as an industry standard in More information see Tektronix. Commands are a series of one or more keywords, many of which take parameters.

If any of the selected bits change from 0 to 1, the instrument generates a Service Request signal. The query returns a string with the following format: This connector did not gain significant market acceptance against the established pin connector.

Condition register bits are updated in real time; they are idee latched nor buffered. Arguments are given after the command, and are separated by a space. Their response format is also the same. Because these operations are common to all instruments, IEEE From Wikipedia, the free encyclopedia.
