General Description
The RX-128 Board has 128 identical receive channels.
The signal in each channel is fed via a Transmit/Receive (T/R) switch to a preamplifier. The next step
is a Time Controlled Gain (TGC) amplifier used to equalize the signal strength from the near field, the
mid field and the far field.
