I can sample four antennas with a single USRP1 using std_4rx_0tx.rbf and
four custom radio receivers connected to basic daugherboars (I tried
this a long time ago). Is there a way of transmitting on four antennas
with a single USRP1. In that case I would need a “std_0rx_4tx.rbf” ? Is
there such an rbf ?
