[Discuss-gnuradio] Cannot Change USRP Interpolation Rate Dynamically

[Firas A.]

Hi,

It seems that there is a bug in gnuradio 3.1.1 (and up to today latest truck
revision)  in the USRP rbf standard file. When trying to change the 
interpolation rate dynamically, the output get distorted badly even if the
program restore the started interpolation value. I have an old gnuradio
3.0.3 (Revision 6082) which does not have this problem at all. Checked with
two  RFX2400 boards, the same problem (it is an FPGA Problem).

To check this , start the test (for example) with interpolation rate 128 and
change it dynamically to 16 (it will be badly distorted). Now, try to
restore it back to 128, and you will see that it stacked at the 16 with
distorted waveform.


Best Regards,

Firas
