PXI is designed for measurement and automation applications that require high-performance and a rugged industrial form-factor. With PXI, one can select modules from a number of vendors and integrate them into a single PXI system, over 1150 module types available in 2006. A typical 3U PXI module measures approximately 100 x 160 mm (4x6") in size, and a
Introduced in 1997, PXI uses the CompactPCI 3U and 6U form factors and adds trigger lines, a local bus, and other functions suited for measurement applications. PXI hardware and software specifications are developed and maintained by the PXI Systems Alliance. [5] More than 50 manufacturers around the world produce PXI hardware. [6]
Room modes are the collection of resonances that exist in a room when the room is excited by an acoustic source such as a loudspeaker. Most rooms have their fundamental resonances in the 20 Hz to 200 Hz region, each frequency being related to one or more of the room's dimensions or a divisor thereof. These resonances affect the low-frequency ...
Virtual instrument software architecture (VISA) is a widely used application programming interface (API) in the test and measurement (T&M) industry for communicating with instruments from a computer.
VCIbus hardware. VME eXtensions for instrumentation bus (VXI bus) refers to standards for automated test based upon VMEbus.VXI defines additional bus lines for timing and triggering as well as mechanical requirements and standard protocols for configuration, message-based communication, multi-chassis extension, and other features.
Room acoustics is a subfield of acoustics dealing with the behaviour of sound in enclosed or partially-enclosed spaces. The architectural details of a room influences the behaviour of sound waves within it, with the effects varying by frequency .
A high-level PXE overview. In computing, the Preboot eXecution Environment (PXE; often pronounced as / ˈ p ɪ k s iː / pixie, often called PXE boot (pixie boot), is a specification describing a standardized client–server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients.
Schematic of a network of rooms where air (shown in blue) flows in one direction from the corridor into the negative pressure room (green). Exhaust air is safely removed from the area through a ventilation system. Negative pressure is generated and maintained in a room by a ventilation system that continually attempts to move air out of the ...
