Bandwidth is the frequency range over which devices meet their accuracy specifications. Accuracy degrades at lower and lower frequencies unless a device is capable of direct current (DC) response. Accuracy also degrades at higher frequencies near resonance and beyond, causing the output response to roll off. Most devices have 3 dB rolloff frequencies.

The number of input channels is the number of possible, simultaneous signal measurements. Channels can be differential or single-ended. Differential channels measure the difference between two signals. Single-ended channels measure the difference between one signal and ground.

Resolution refers to the degree of fineness of the digital word representing the analog value. A ten-bit number contains 210, or 1024, increments. Therefore, a 0 - 10 V signal can be resolved into approximately 0.01 V increments. A 12-bit representation is in 212 (4096) increments, or divisions of 0.0024 V for the same signal. Each additional bit doubles the resolution, and one bit is required for the polarity (sign) of a number.

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.
Modems are devices or programs that enable a computer to transmit data over telephone lines. Computer information is stored digitally, but information sent over telephone lines is transmitted in the form of analog waves. A modulator-demodulator or modem converts the data between these two forms.
Ethernet is a local area network (LAN) protocol that uses a bus or star topology to support data transfer rates of 10 Mbps. It is one of the most widely implemented LAN standards.
The Ethernet specification is the basis of the IEEE 802.3 standard, which specifies the physical and lower software layers. To handle simultaneous demands, Ethernet uses carrier sense multiple access with collision detection (CSMA/CD).
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 know as the IEEE 488 bus, and is electrically equivalent to the IEC 625 bus.
Small computer systems interface (SCSI) is an intelligent I/O parallel peripheral bus with a standard, device-independent protocol that allows many peripheral devices to be connected to the SCSI port. A single SCSI bus can drive up to eight devices or units: the host adapter or controller, and seven other devices. Each device is assigned a different SCSI ID, ranging from 0 to 7. SCSI formats include SCSI-1, SCSI-2, SCSI-3, Wide SCSI, Fast SCSI, Wide Fast SCSI, Ultra SCSI, Ultra2 SCSI, Ultra3 SCI (Ultra160), Ultra 320 SCSI, and Ultra640 SCSI.

Devices can monitor and/or display currents and voltages associated with electrical power or high-power switching such as relays or opto-isolators. Typically, these currents and voltages are much higher that standard sensor signal levels.
Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. RoHS will become effective on July 1, 2006.
“The Waste Electrical and Electronics Equipment Regulations (WEEE Regulations) is a European Parliament Directive with the aim of encouraging reuse, recycling and recovery of electrical and electronic equipment, and to improve the environmental impact and performance of these equipments. This directive sets the requirements and criteria for the collection, treatment, recycling and recovery of these equipments. It makes producers responsible for financing these activities, and retailers and distributors must provide means for consumers to return used or obsolete equipments without charge.
