Analog Output Channel Pad Configuration
Table 3-1 correlates the component labels of the SCB-68A to component locations A and B for
analog output channels 0 and 1.
Lowpass Filtering
Lowpass filters highly or completely attenuate signals with frequencies above the cut-off
frequency, or high-frequency stopband signals. Lowpass filters do not attenuate signals with
frequencies below the cut-off frequency, or low-frequency passband signals. Ideally, lowpass

must
remove the resistor to use the position.
If you remove your custom components from the A position, you
must
reinstall a 0
