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.

Filter Specifications
   Integral Filter?       Integral filters allow certain signal frequencies to pass while attenuating others. These filters can also operate on signal phase. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Filter Architecture:       
   Your choices are...         
   Analog (RC)       Analog filters are designed with resistors and capacitors. They are used for analog signals only, and are often used in low-noise requirement applications. 
   Digital (FIR, IIR)       Digital filters are designed with solid-state components and used for digital signals and quantized signals from a sample-and-hold amplifier. This category includes finite impulse response (FIR) and infinite impulse response (IIR) filters. Digital filtering can approach ideal bandpass characteristics. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Number of Poles:      Poles are a measure of complexity of the filter circuitry. In general, more poles will provide a steeper roll-off for a given filter type.

   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   High Pass Cutoff Frequency       The high pass cutoff frequency is the nominal frequency above which the input signal is passed and below which the signal is blocked. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Anti-aliasing Filter?       Aliasing is the misrepresentation of a signal that comes from an improperly slow sampling of a signal. An anti-aliasing filter generally has a sharper cut-off than a normal low-pass filter to reduce this misrepresentation due to the influence of frequencies higher than desired. It is specified according to the sampling rate of the system and there should be one filter per input signal. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Programmable Filter?       Filter parameters such as cutoff frequencies may be interactively programmed by user.
