[Discuss-gnuradio] USRP 2 Daughter Cards

[jim graham]

I am trying to use the USRP 2 radio.  I have been using the rx_streaming_sample script to collect data.

 

If I use the rfx1800 daughtercard the results from the set_center_freq command seem correct but the output

looks as if the receive channel is not connected (changing gain does not affect output levels).

 

If I try the lfrx or dbs daughter cards the set_center_freq response appears incorrect.

The baseband frequency is 0 and the ddc frequency is the negative of the commanded frequency.

 

Any suggestions?
