- I have 2 RFX900 and a USRP, when positioning my RFX900 boards on USRP
motherboard, the two RFX900 boards should be oriented in opposition
direction and as long as the four holds of the RFX900 boards matched with
the USRP motherboard’s, I am putting it correctly right? I just want to
confirm it before I charge up the board.
Yes, RX side A is next to the TX on side B and vice-versa:
The holes on the daughter boards must line up with the holes on the main
board. Make sure!! Put in the screws if you must.
- In chapter 4 of the gnuradio tutorial, it mentioned that I can test my
USRP configuration by " Then connect your speaker to the sound card and
insert a piece of wire to the RX-A connector" , How to insert " a piece of
wire" to the RX-A connector. What kind of wire do I need and what should I
connect the wire to on the other end?
Perhaps if you have a basic RX daughter board, you could stick a wire
into the SMA connector and get some FM or AM audio signals. Any type of
wire will do, just strip it and stick it into the center hole on the
Same for the TVRX daughter board.
- Is there any other ways of testing my USRP configuration?
Sorry for asking so many questions. I hope to be able to get started
quickly and be able to contribute back to the community as much as I can.
You can do a loop back test. Connect the RX to the TX, generate a signal
with usrp_siggen.py and receive the signal with usrp_fft.py.
Make sure you check usrp_fft.py --help and usrp_siggen.py --help and get
all the options right.
Thanks in advance for all your help.
If you are feeling adventurous, install the latest gnuradio development
trunk or the 3.2 release candidate branch and check out GRC:
