[USRP-users] problem with RFNoC block not outputting

2017-09-11 Thread Jason Matusiak via USRP-users
I have a block that I've been working on and it seems like I am missing something vital to get it to work properly. My block takes in a vector of 2048 samples and outputs 2048 samples as well. I simulated it and it passes simulation fine. But, if I look at the output as it goes to a file, no

[USRP-users] B210 -- AD9361 low-level access and changing filter configuration

2017-09-11 Thread Rob Heig via USRP-users
Hi, I have been playing a bit with the API of UHD and I wonder if it is possible to have a low-level access to the underlying, low-level AD9361 API. In effect, what I would love to do is to play with the filters (the RX FIR filter in particular), but so far I haven't been that lucky (all I've mana
