Hi,
I am using XCVR 2450 + USRP2 (Rev 4.0). Before they works fine.
However, I just found out one of them can not set frequency recently :(
The problem statement is as follows:
gbzh...@gbzheng-desktop:~/downloads/ofdm_example$ sudo python
benchmark_ofdm_tx_new.py --mac-addr=00:50:c2:85:3a:ff -f 2.412G -m qpsk -i
100 --tx-gain=30 -M 8 -s 1000
Requested TX Bitrate: 100k Actual Bitrate: 500k
Failed to set Rx frequency to 2.412G
Traceback (most recent call last):
File "benchmark_ofdm_tx_new.py", line 146, in <module>
main()
File "benchmark_ofdm_tx_new.py", line 104, in main
tb = my_top_block(options)
File "benchmark_ofdm_tx_new.py", line 41, in __init__
self.txpath = usrp_transmit_path.usrp_transmit_path(options)
File "/home/gbzheng/downloads/ofdm_example/usrp_transmit_path.py", line
67, in __init__
self._setup_usrp_sink(options)
File "/home/gbzheng/downloads/ofdm_example/usrp_transmit_path.py", line
90, in _setup_usrp_sink
raise ValueError, eng_notation.num_to_str(options.tx_freq)
ValueError: 2.412G
I tried different frequency band in 2.4GHz ISM bands, as well as different
scale value like 2412000000. however, the result has no luck.
Does it mean the broken daughterboard?
Thanks,

Guanbo
