[Discuss-gnuradio] test_usrp_standard_tx Could not set frequency

[proulx1]

Hello,

I am new to the GNU Radio.  I have been following the steps outlined in 
http://gnuradio.org/trac/wiki/UbuntuInstall, and I am at the point where I am 
testing.
The command:
ls -lR /dev/bus/usb | grep usrp
shows a single USRP, which is correct.

usrp_benchmark_usb.py
Passes everything but the 32 Mb/s test.

But when I try to run:
test_usrp_standard_tx
I receive this output:

which:    0
interp:   16
rf_freq:  -1
amp:      10000.000000
nsamples: 3.2e+07
Subdevice name is XCVR2450 Tx
Subdevice freq range: (2.4e+09, 6e+09)
mux: 0x000089
baseband rate: 8e+06
Fail 4200000000.000000
terminate called after throwing an instance of 'std::runtime_error'
  what():  Could not set frequency.
Aborted


This is on a USRP, with two XCVR2450 daughterboards.  I looked through the 
wiki, mailinglist, and the web, but I did not find anyone who had this problem.

Thank you for your help,
Brian Proulx
