Build should fail with 1000 coefficients and a Window Block instance. The most taps I've gotten is 334 with a DUC and DDC instantiated along with the FIR. If I instantiate 2 Digital Gain blocks with 2 FIR blocks, the most taps I could build was 186 taps for each FIR. These were found through trial

[USRP-users] problem to work witth source file and RFnoC block and FIR block

Hi all, I am working on a USRP X310 with a source file block and I have some issues. My setup is : Source File -> Throttle -> RFNoC: Window -> RFNoC: FIFO -> Copy -> Vector to Stream -> File Sink. When I run this flow-graph in the first time, the output is fine and I can see that the file sin
