[Discuss-gnuradio] Problem of Daughterboard XCVR 2450

[Guanbo Zheng]

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:
address@hidden:~/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,
