The usrp2_fft python code was recently changed to use that
adc_rate() call, although the actual implementation returns the value to the
input pointer parameter.
Just change that line in usrp2_fft back to what it was so you
can at least test it:
From:
input_rate = self.u.adc_rate() / self.u.decim()
To:
input_rate = 100e6/options.decim
This simply a quick fix, I’m assuming the adc_rate
function will be changed to return the value the same way as decim() does.

Subject: [Discuss-gnuradio] USRP2 AttributeError:
'usrp2_source_32fc_sptr' object has no attribute 'adc_rate'¨
Hello,
I tried to run usrp2_fft.py to test my USRP2 board and I got the following
error.
¨AttributeError: 'usrp2_source_32fc_sptr' object has no attribute 'adc_rate'¨
./find-usrps script is running fine with following result.
00:50:c2:85:30:0a hw_rev = 0x0300
My configuration is
-Ubuntu 8.04, with the latest svn (7 days old)
- I am using Netgear Gigabit switch to connect to fast Ethernet port on my
laptop. I could not directly connect my Gigabit PCMCIA card to USRP2.
Do you think this error is due to any configuration setting?
Thank you,
-C
