Description
The Receiver Monitor capability is checked by looping the transmitter output to re-
ceiver input through a series of matching pads and selectable fixed attenuators. The
total attenuation of this loop is calculated to be the same as the selected Monitor at-
tenuation. A BER measurement is run and a check made for no errors in the results
page for each selection of Bit Rate and monitor attenuation.
