| Term | Definition |
|---|---|
| I2C | I2C (Inter-Integrated Circuit) - a serial two-wire bus used for low speed communication between peripherals and controller and in embedded systems. |
| IEEE-488 | Short range digital communications bus originally invented in the late 1960s by Hewlett-Packard for automatic test equipment. Also known as HP-IB, GP-IB and GPIB. |
| impedance | Opposition to a AC current when a voltage is applied. Equivalent of resistance in DC circuits. |
| input impedance | Shunt resistance and capacitance measured at the input terminals. |
| interleaving | Two or more channels are combined and used alternately to achieve higher sampling rates. |
| JEDEC | JEDEC Solid State Technology Association - develops open standards and publications for the microelectronics industry. See www.jedec.org/ |
| kbit/s | Kilobit per second = specifies a date rate i.e. 1,000 bits transfered per second. |
| kHz | 1,000 Hz. Unit of frequency. |
| Kilohertz | 1,000 Hz. Unit of frequency. |
| linearity | Deviation of a response from a straight line. |
| LXI | LAN eXtensions for Instrumentation = instrument control standard based on LAN (local area network) and Ethernet technologies. Specified by the LXI Consortium. More information see http://www.lxistandard.org/ |
| M-PHY | MIPI Physical Layer Specification - this is the second specification developed by MIPI primarily to support a much broader range of applications, including interfaces for display, camera, audio, video, memory, power management and communication between Baseband to RFIC. More information see www.mipi.org. |
| matrix | Switching device that connects mulitple inputs/outputs to mulitple inputs/outputs. |
| Mbit/s | Megabit per second = specifies a date rate i.e. 1,000,000 bits transfered per second. |
| Megahertz | 1,000,000 Hz. Unit of frequency. |
| memory depth | Normaly specified in MS (megasamples) per channel. This value indicates how many measurement values of the analog-digital converters (ADC) can be stored per channel. The total acquisition time for a given signal is depending on the sample rate and the memory depth per channel. This is especially important for non repetitive signals. |
| MHz | 1,000,000 Hz. Unit of frequency. |
| mHz | 0.001 Hz. Unit of frequency. |
| Millihertz | 0.001 Hz. Unit of frequency. |
| MIPI | Mobile Industry Processor Interface - open membership organization that develops interface specifications for the mobile ecosystem founded in 2003. More information see www.mipi.org. |
