device driver<br />

Software code that communicates with a device: for<br />

example, a printer driver that communicates with a<br />

printer from a PC. A device driver may either<br />

communicate directly with a device by reading to and<br />

writing from registers, or it may communicate through an<br />

interface driver.<br />

device session<br />

A session that communicates as a Controller with a single,<br />

specific device such as an instrument.<br />

device-level<br />

Refers to <strong>Agilent</strong> 488 functions that operate on a device<br />

(instrument), rather than on an interface.<br />

direct I/O<br />

Programmatic communication with instruments not<br />

involving an instrument driver. Direct I/O may be<br />

accomplished by using an <strong>IO</strong> Library (VISA, VISA COM,<br />

SICL, or <strong>Agilent</strong> 488) or by using direct I/O tools such as<br />

those provided by <strong>Agilent</strong> VEE and <strong>Agilent</strong> T&M Toolkit.<br />

shows all devices connected to a test system.<br />

A software routine that responds to an asynchronous<br />

event such as an SRQ or an interrupt.<br />
