GPIB cable

GPIB cable

Product Details

Connect the system to GPIB devices or interfaces, suitable for instrument control applications in different environments from the laboratory to the factory floor.

National InstrumentsGPIB, also known as IEEE488 standard bai, is an international bus standard (just like a USB bus), which has standard electrical requirements and command set requirements. From this perspective, dao teaches that your connection plan is feasible and can complete the basic management requirements

what isGPIBline?

The GPIB cable is composed of 12 pairs of copper-core twisted pairs and uses a 24-pin parallel male/female connector.

how to useGPIBline?

When the GPIB line is in use, the connectors form a bus or star structure by "piggybacking" each other, and then connect the test and measurement equipment to a PC or other equipment.

GPIBWhat are the use occasions of the line?

GPIB lines are commonly used in test and measurement applications, and data acquisition (DAQ) fields.

IEEE-488Explanation of Bus Related Terms

adapter:A device used to connect two different types of connectors.

American wire gauge(AWG):Started in the United States, a set of standards used to distinguish the diameter of non-ferrous metal wires. The wire gauges of typical data cables are 24 AWG, 26 AWG, and 28 AWG. The larger the number before AWG, the smaller the corresponding diameter and the thinner the wire.

Back shell (outer shell):A mechanical support that is usually used to wrap the connector to protect the conductor. The production process can be assembled or injection molded.

bus:Also known as "daisy chain mode", it belongs to a network topology, in which each node is linearly connected to each other, which makes this mode have an obvious defect, that is, any breakpoint in the bus will cause the entire network to paralyze .

Cable:A group of insulated wires or conductors, the outer layer is wrapped with an extruded sheath. Many types of cables are equipped with a shielding layer between the conductor and the sheath.

Cable assembly:A cable with one or more connectors terminated.

conductor:Metal (mostly copper) vias, conductive. When used to describe data lines, "wire" (wi re) and "conductor" are synonymous.

Connector:An electromechanical connection device with a pluggable electrical interface.

Contact:The specific contact point part of the connector. The contact can be male (pin) or female (socket).

Coupler:A device used to connect two connectors of the same type.

Crosstalk:Refers to the coupling effect produced by the electromagnetic field between adjacent conductors. Just make the wire into a twisted pair or separate the wire (shield), and the crosstalk interference can be controlled.

Electromagnetic interference (EMI):The unwanted electromagnetic or electrical energy generated in electronic equipment is harmful to the equipment.

GPIB:General Purpose Interface Bus is the common name of IEEE-488.

HPIB:Hewlett Packard Interface Bus is the common name of IEEE-488.

IEEE-488:Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers) Interface Standard No. 488.

Injection molding:The process of injecting molten polymer into a mold. The connector back shell usually adopts injection molding process.

Insulator:The material with extremely high resistance is used to protect the conductor. Usually, after the wire drawing process is completed, the insulating material is evenly covered on the outer layer of the wire by extrusion.

Insulation displacement contact (IDC):A method of terminating wires without the need to split the cable into bare wires.

socket:The female connector-usually a port configured on the device.

plug:That is, various types of male connectors.

shield:A layer of conductive foil or braid used to cover insulated wires in a cable. The shielding layer has a grounding effect, resists external electromagnetic interference (EMI), and at the same time controls internal electromagnetic radiation.

Net tail:It is used to protect wires and connections so that they can withstand bending and drag stress.

Twisted pair:Refers to the winding of two insulated wires according to a certain number of twists within a unit length. Usually used in balanced circuits that require strict control of rated impedance and crosstalk.

wire:It is made of conductive material (mostly copper material), with a wire drawing process to reach a standard diameter, and evenly covered with insulating material. "Bare wire" refers to wires without insulation.
