Re: [USRP-users] Is it possible to manually configure any filter in AD/FPGA

2017-11-03 Thread Brais Ares via USRP-users
Hello Marcus, No, I'm pretty confident about what UHD can do. The thing is we need to tweak with FPGA design to alleviate some cpu load in our host and do some multichannel filtering. We'd like the AD to just decimate by a factor of 8 (61.44 -> 7.68 MHz) and also be able to configure its channel

[USRP-users] Pybombs installation fails

Re: [USRP-users] Setting LO offset and exact central frequency with RFNoC

2017-11-03 Thread Derek Kozel via USRP-users
Hello Dragoslav, What you are seeing is expected and correct. With the multi_usrp interface the set_tx_freq function does a series of actions for you. 1) Calculate a target RF frequency, taking into account any LO offset requested 2) Call a function to set the RF frequency to this target and then
