Re: [Discuss-gnuradio] Any one know rfx board i q imbalance value

The imbalance will vary board to board, which is why we provide the ability to calibrate the IQ balance. Running the calibration utility will get you the best performance. Matt On Fri, Mar 8, 2013 at 5:54 PM, James Jordan wrote: > Hi list, > Anyone know rfx board i q phase imbalance value and

Re: [Discuss-gnuradio] Number of bits tranmitted

One idea would be to have a file sink also attached to the GMSK Mod block. All samples you send to your USRP would be copied in the file. Just check the file for byte count. Tommy James Tracy II Ph.D Student High Performance Low Power Lab University of Virginia Phone: 913-775-2241 On Mar 8, 201

Re: [Discuss-gnuradio] How to know the number of bits/packets transmitted

You have your input on repeat, so it'll keep transmitting as long as the program is running. Are you looking for the rate, or the total bit count? Tommy James Tracy II Ph.D Student High Performance Low Power Lab University of Virginia Phone: 913-775-2241 On Mar 8, 2013, at 7:11 PM, manjusha wro

Re: [Discuss-gnuradio] Terminal commands

Hi Manjusha, what you most propably want to do is something of the like # ncat -l -u 12346 to see what your deframer spits out. To see what your transmitter is going to transmit, you should use whatever software generates the data and sends it to port 12345. Presuming you're using the ubiquitous
