Re: [USRP-users] RFNoC: FIR Filter final tap never gets written to settings register

Hey Andrew, The next line in fir_block_ctrl_impl.cpp sends the final tap: sr_write(SR_RELOAD_TLAST, uint32_t(taps.back())); The half a sample shift is odd though. On Sat, Apr 21, 2018, 6:23 AM Marcus D. Leech via USRP-users < usrp-users@lists.ettus.com> wrote: > On 04/20/2018 12:01 PM,

[USRP-users] RFNoC: FIR Filter final tap never gets written to settings register

Hello, An oddity regarding the RFNoC FIR Filter block. fir_block_ctrl_impl.cpp writes tap values to the settings registers with: for (size_t i = 0; i < taps.size() - 1; i++) { sr_write(SR_RELOAD, uint32_t(taps[i])); } which loops from 0 to taps.size() - 1. So if I define 41 taps from

Re: [USRP-users] Core dump with UHD_3.11, X310, and LFTX

I have an issue that may be related. Using LFTX and LFRX boards in an X310, anytime I use the RFNoC Radio block in Rx mode the run terminates with: terminate called after throwing an instance of 'std::out_of_range' what(): map::at Following for updates. Andrew On Thu, Apr 19, 2018 at 9:54

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

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

Re: [USRP-users] DC Offset Calibration Issue for Rev. C UBX-40 daughter cards

Thanks for the insight. Is this publicly documented anywhere? The USRP web manual (https://files.ettus.com/manual/page_calibration.html) still explicitly states to leave RF ports disconnected for calibration. Updating that page ASAP could save folks out there a lot of grief… From: Michael West

[USRP-users] Configuring FIR filters for b210

Hi all. I have a b210 device on which i want to make a transceiver. I managed to replicate 15Mhz bandwidth, but now i want to configure the FIR filters, to eliminate 10 Mhz from the bandwidth from RX and transmit only 5 Mhz on TX. I tried to make a low pass filter, to configure the taps, using
