Phase | |||
Your choices are... | |||
Single Phase | Standard commercial and residential power is single-phase, meaning one sinusoidal or other alternating voltage pattern. | ||
Three Phase | Three-phase power contains three simultaneous sinusoidal or other alternating voltage patterns, typically 120° out of phase with each other. Higher power efficiency and smoothness of operation is possible with three-phase operation. Three-phase power is most typically used for industrial or high power motors. | ||

GPIB | The general-purpose interface bus (GPIB) is designed to connect computers, peripherals and laboratory instruments so that data and control information can pass between them. It was originally developed by Hewlett Packard (HP) and called the HPIB bus. GPIB is also known as the IEEE 488 bus, and is electrically equivalent to the IEC 625 bus. | ||
USB | Universal serial bus (USB) is a 4-wire, 12-Mbps serial bus for low-to-medium speed peripheral device connections to personal computers (PC), including keyboards, mice, modems, printers, joysticks, audio functions, monitor controls, etc. The USB design is standardized by the USB Implementers Forum (USBIF), an organization that includes leading companies from the computer and electronics industries. The current USB specification is USB 2.0, which supports data transfer rates of up to 480 Mbps. | ||
RS232 | RS232 is a serial interface approved by the Electronic Industries Association (EIA). RS232 uses two-way transmissions and is common in low-end professional and consumer equipment. | ||
BCD | Binary coded decimal (BCD) is a circuit code which represents decimal numbers in binary code. With BCD, each decimal digit is represented by the four-bit binary representation of the digit. | ||
D/A | The output interface is digital-to-analog (D/A). | ||
Ethernet | Ethernet is a local area network (LAN) protocol that uses a bus or star typology and supports data transfer rates of 10 Mbps. The Ethernet specification is the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. To handle simultaneous demands, Ethernet uses carrier sense multiple access / collision detection (CSMA/CD) to monitor network traffic. | ||
Wireless | The device has a wireless connection as its interface. | ||
