Device Specifications
   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 numbers 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. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Accuracy       Accuracy depends on the signal conditioning linearity, hysteresis, temperature considerations, etc. It is represented here as percent full scale of measurement range. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Bandwidth       Bandwidth is the difference between the high and low limits of the frequency response, typically defined by a variation from a nominal value by a stated value such as 3 dB. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Maximum Output       This is the limit of output voltage. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Signal Isolator       Signal isolation is the separation of any direct electrical contact of a signal. This can be done in various ways, including optical isolation, capacitors, and magnetic induction. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Sensor Multiplexer       Multiplexers handle several inputs and combine them serially into one output for transmission. Some multiplexers perform the reverse function. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
