This page describes the 40m Upgrade '''Frequency Distribution Box'''.

The box is going to be installed in the LSC rack. It will get the demodulation signals from the [[/frequency generation box|frequency generation box]] and it will split it into several output so that it can be used by the demodulation boards.

The box is also going to generate frequency multiples as 3xf1, 3xf2, 2xf1 and 2xf2 demod signals.
