To: "j...@joshknows.com" <j...@joshknows.com>
Hi Josh,
I am using USRP 1. I am using a sma-bulkhead cable from Tx_A
of basic tx daughter board and similarly a sma-bulkhead cable from Rx_A
terminal of the Basic Rx daughter board. and then i am connecting a sma-sma
cable from usrp transmitter to a coupler on powerline cable. Similarly I am
connecting a sma-sma cable from usrp receiver to another coupler on the
powerline cable.
so in all I am using 2 usrp 1, 2 sma-sma cables, 2 sma-bulkhead cable and
two couplers. Please let me know if i am not clear with the description.
Thank you.
