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.
|
| |
Modem

|
|
|
|
| |
Inputs / Channels:
|
|
This is the maximum number of analog channel inputs. The single-ended number is specified when single-ended inputs are available as twice the number of differential inputs. Differential channels use the difference between two signals as an input; common mode is filtered out. In some systems, differential inputs are combinations of two single-ended inputs. When this is the case, twice the number of differential channels are available as single-ended inputs.
|
| |
Search Logic:
|
|
All matching products will have a value greater than or equal to the specified value.
|
|
| |
Differential Channels
|
|
Differential channels have two inputs. The signal to process is the voltage (V) difference between the two inputs. For example, if one reading is 4.93 V and the other reading is 5.16 V, the meaningful value is the 0.23 V difference between the two. Often, this applies to precision measurements where the difference between two low voltage inputs is small but critical.
