Log RF to basedband waveform
User can use this platform as a scope to easily log baseband I/Q data from RF signal into a variable in
MATLAB. The maximum receive length is about 8e7 samples.

log length
rk is the variable of the I/Q data. The maximum length of rk is about 8e7 samples, which depends on the
size of RAM of user’s computer. User can check the time domain waveform and frequency domain power
spectrum density (PSD). Here show the measuring results as follows.
