Hi Everyone,
I have been looking at the rfx900 schematic and there something I don't
understand. The transmitter system is specified to work over the 750 to
1050MHz range buy the synthesizer is specified to work over the 2400 to
2725 or 1200 to 1362MHz range. As the input to the transmitter is a
I made changes to the wfm_rcv_pll.py and usrp_wfm_rcv_pll.py that I believed
were necessary.
I modified the bandwidth of the PLL in wfm_rcv_pll.py to comply with
"Carson's rule". I modified the audio output to be 48 kHz using rational
resamplers.
If there are any problems, please let me

Verilog simulators can

Excuse me if this is totally off the wall, but since if you r
You mean as in simulink (matlab only)? Or as a standalone (.m file)
matlab/octave program?
Is there a fixed point rough equivalent for Octave?

I'm looking to model the rx_chain of the USRP using MATLAB's fixed
point toolbox and I'm wondering if anyone has tried this yet in MATLAB
or Octave.
Thanks,

Hi Eric,
Two nodes, each consists of one USRP and an RFX2400, are involved, one as a
Master(Transmit ... receive echoed version...Transmit new packet and so on)
and the other USRP is Slave (Receive...echo back the received packet). I am
creating 1 usrp source (for transmitting) and 1 usrp sink (f
