In E3xx simulink block, the valuable is tunable. However, I try to use a spectrum analyser to monitor the output of the Tx radio. It turns out that the signal strength is very low. I tried the 0db value. When I put the antennas of the TX and the spectrum analyser very close, the signal is about -40dbm, Which is near 0 dbm in the order version of simulink block of this type. There seems to be some mistake in the new released simulink block E3xx.
