[Discuss-gnuradio] USRP2-FLEX2400 Transmit and Receive problems

Hi,

We are currently experiencing Transmit and possibly Receive problems
with the USRP2-Flex2400 boards.

- The USRP2 is detected:
# find_usrps -e eth0
00:50:c2:85:32:73 hw_rev = 0x0400

- The latest firmware and Raw Ethernet FPGA images have been written
onto the SDRAM: u2_rev3-20100603.bin, u2_rev3-20100603.bin

- To test receive, we transmit a 2.4GHz, 10 dBm RF signal using the HP
8350B Sweep Oscillator/Signal Generator. This is detected by both the
USRP2-FLEX2400 (using usrp2_fft.py script) and Agilent Spectrum Analyzer
(Please see screen shots attached). However, the usrp2_fft.py shows some
odd sidebands around the the 2.4GHz central frequency when the signal
generator is turned on.

- Both LEDs D and F are lit up.

- Gnuradio version 3.2.2 is being used on Ubuntu Lucid Lynx (10.04).

We then turn off the Signal Generator, and transmit a 2.4GHz signal
solely using the USRP2-FLEX2400 by running 'usrp2_siggen.py -f 2.4e9 -e
eth0'. Nothing gets picked up by the Agilent Spectrum Analyzer
USRP2-FLEX2400.

Is there a USRP2-FLEX2400 transmit/receive problem while using the
latest firmware and raw ethernet FPGA code?

Thanks,
Jaw.
