I've been trying out RX and TX with a system using a Raspberry juice board.
Summarised the results of this experiment, attached the file.
The juice board can be used to receive up to 6RX slices at 384KHz sampling.
And the juice board works via a USB connection. So can connect to PC direct.
please note that CPU utilization will be a bottleneck on older PCs and RPi at higher sampling rate.
For TX, I put a resistor between the terminals of the TxDAC to reduce non-harmonic spurious and saw the change.
And I tried the circuit with a BPF inserted.
VerilogHDL changes:
Switching BPF at 10m/12m
FAN-PWM signal output
Many thanks to Johan pa3gsb for his ideas and advice.
Tnx.
