Test_usrp_standard_tx Could not set frequency

GNU Radio
1

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

The XCVR2450 covers 2.4-2.5 GHz and 4.9 to 5.85 GHz. Try tuning to
something in these ranges.

Thanks for your patience with me. Setting it to 2.41GHz worked.
