RX Constellation Monitor Port
To display the receive constellation on an oscilloscope, connect the I and Q signals to the
main X/Y inputs and apply the receive symbol clock to the external trigger input of the
oscilloscope. The main oscilloscope inputs should be set to X/Y display, AC coupled, both
channels on 200 mV/div, with the trigger from the external trigger input.
