The theory of operation for the receiver is split into two sections that cover the ET models
and the ES models.
8712ET and 8714ET Receiver Assembly
The main function of the receiver assembly is to separate and measure signals associated
with the DUT (device under test) and convert those signals to digital data for further
processing on the CPU board. The receiver assembly also routes the RF signal to the DUT.
