USRP2 TX fail

I try SBX and WBX but the result is the same. TX fails and RX succeed.
The following is the summary usrp2, operated in gnuradio 3.2.2 with
corresponding firmware download from ettus web can TX and RXusrp2,
operated in gnuradio 3.6.2 with corresponding firmware download from
ettus web can RX but fail to succeed.
The test program used are uhd/usrp2_siggen, benchmark_tx and
benchmark_rx and bbn80211_tx and bbn80211_rx.
I think the problem may be related with firmware in 3.2.2 version, but
if it is the problem it is hard to explain why it can RXThank you.

Which port is your antenna connected to? In SBX/WBX daughterboards, you
can only transmit through Tx/Rx. However, you can receive through both
Tx/Rx and Rx2.

This might not be related to your problem. But just checking.

Thanks,

Dear Guys, I encounter one strange problem, I can use usrp to
receive signal but cannot transmit signal. My usrp is USRP2 and gnuradio
version 3.2.2. When running ursp2_siggen.py, it do not return any
error but when I use a spectrum analysis, it shows no signal is
transmitted.
When running benchmark_tx.py and bbn80211_tx.py, it also reports
no error, but there is no signal sent out. Do you guys have any
advice?
Thank you.
