Analog Input 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.

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.
