5.4 Checking BPSK waveform

5.4 Checking BPSK waveform

To check the strength of the RX signal and the synchronization status, the Lissajous
waveform which is the CPU processed BPSK signal is observed. For example, the
disconnection of the antenna coaxial cable connector is found out by observing the
waveform.
