[Discuss-gnuradio] base band signal sample frequency in RFX 900 daughter board

Hi, I use USRP1 and RFX 900 daughter board to receive an 925MHz signal. The receiver configuration code is shown below. Some people told me that the RFX 900MHz board will do down conversion and convert the 925MHz signal to a base band signal automatically. Can you tell me what is the frequency to

Got it. How to figure out the frequency USRP1 uses to digitize the signal? Is 64M samples/sec the default configuration? Thanks. On Thu, Aug 9, 2012 at 11:21 AM, Ed Criscuolo edward.l.criscu...@nasa.govwrote: On 8/9/12 11:09 AM, pengyu zhang wrote: Receiver's configuration code: rx =

Swig stuff are python bindings to C or C++ code. So in your example pfb_clock_sync_ccf() has been coded in C++, and _digital_swig.pfb_clock_sync_ccf() is the generated python wrapper to access the C++ pfb_clock_sync_ccf() from a python script. The C++ code is in include/ and lib/, swig bindings

Hi all, Just a little question about the behavior of the DUC cordic: The DUC cordic resets phase when a new transmit burst begins (e.g. after a long underflow). Does this also happens when a packet with a new SOB-tag (and associated time-tag) arrives at the USRP? Thanks a lot,
