Adding Signal Conditioning Components
The BNC-2090A has open-component positions in the input paths into
which you can insert resistors and capacitors for conditioning the
16 single-ended or eight differential analog input signals and the
two analog output signals. You can also use the BNC-2090A in
conjunction with other signal conditioning accessories.
Figures 3-1 through 3-13 give examples using a specific channel. If you
want to install the circuit in a different channel, consult Table 3-1 to
determine the equivalent component positions for the other channels.
Complete the following steps to add signal conditioning components to the
BNC-2090A, as shown in Figure 3-14.
