1
The Input Bandwidth specification only applies to signals to the modules; it does not apply to signals applied to the
External Signal Input and sent back to the External Signal Output.
2
The Output Bandwidth specification only applies to signals from the modules; it does not apply to signals applied to the
External Signal Input and sent back to the External Signal Output.
