»
The SCC-LP Series lowpass filter modules contain fourth-order
Butterworth filter circuitry. They accept two differential input signals
within a ±10 V range. A differential amplifier attenuates each signal by
a factor of two. The output of the amplifier passes through a fourth-order
Butterworth filter circuit.
The SCC-LP Series consists of the following modules:
• SCC-LP01—25 Hz cutoff frequency
• SCC-LP02—50 Hz cutoff frequency
• SCC-LP03—150 Hz cutoff frequency
• SCC-LP04—1 kHz cutoff frequency
The following conventions are used in this guide:
Angle brackets that contain numbers separated by an ellipsis represent
a range of values associated with a bit or signal name—for example,
P0.<3..0>.
