GPIB Protocol Compatibility
   GPIB Protocol Compatibility:       
   Your choices are...         
   IEEE 488.1       Devices are compatible with ANSI/IEEE Standard 488-1975, more commonly known as IEEE 488.1. This standard defines the mechanical, electrical, and protocol specifications for the interconnection of programmable instruments. IEEE 488.1 also specifies that a GPIB network supports a maximum of 14 devices on the bus and a maximum data transfer rate of 1-MBps. 
   IEEE 488.2       Devices are compatible with IEEE 488.2, an enhanced version of the original IEEE 488.1 Standard. Because IEEE 488.1 did not specify issues such as how data should be formatted, how the status of the bus should be reported, and how messages should be exchanged, Tektronix proposed a set of standard formats that became the basis of IEEE 488.2.  Specifically, IEEE 488.2 standardizes data formats, status reporting, error handling, and controller commands. 
   HS488       High Speed 488 (HS488) is a newer, faster protocol developed by National Instruments that accelerates data transfer rates up to 8-MBps using standard GPIB cables. HS488 is a superset of the original IEEE 488.1 standard implemented at the hardware level by an application-specific integrated circuit (ASIC).

General Switch Specifications
   Switch Topology:      There are three main types of functional topologies for switches:
  • General-purpose
  • Multiplexers
  • Matrix
   Your choices are...         
   General Purpose       General-purpose devices are simple switches that consist of independent and isolated relays or field-effect transistor (FET) switches. They can connect one input to one output. 
   Multiplexer       Multiplexers connect one input to several outputs, or several inputs to one output. 
   Matrix       Matrix switches have several inputs and several outputs. Any number of inputs can be connected to any number of outputs. 
   Other       Other combinations such multiplexer/matrix, a switch arrangement that can be connected as a multiplexer or as a matrix. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Switch Type:       
   Your choices are...         
   Relay Switch       The switch has a mechanical relay to rout or switch signals. It is used to switch or scan high voltage signals. There are three types of products: armature, dry-reed, and mercury-wetted switches. The relay type can be SPST (single-pole or 1-wire, single-throw), SPDT (single-pole or 1-wire, double-throw), or DPDT (double-pole or 2-wire, double-throw). 
   Solid State Switch       Solid-state switches use transistors (FETs and others) to route or switch signals. They are used in applications that require high-speed scanning of low-level signals (±10 V). Because they do not have any moving parts, solid-state switches have a very long life. 
   RF Switch       RF switches are ideal for routing high-frequency signals. 
   Other       Other unlisted switch types such as optical switches. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Relay Type:      The type of the mechanical relays of the switch.
   Your choices are...         
   SPST       The relay type is single-pole, single-throw (SPST). There are two types of SPST relays: Form A (normally-open) and Form B (normally-closed). 
   SPDT       The relay type is single-pole, double-throw (SPDT). This contact type is also known as a Form C.  
   DPDT       Double-pole, double-throw (DPDT). 
   FETs       The switch is a solid-state device and the relay is a field-effect transistor (FET). 
   Other       Other types of relays. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
