Re: [USRP-users] USRP B2xx Tx Peak power mode

Dear Marcus, I use the same signal for NI-5672 and signal changes as expected, I change A from 2000 to 8 and it must drop 46 dB but does not! On Tue, Aug 6, 2019 at 4:09 AM Marcus Müller wrote: > Dear Hossein, > > the B200 does NOT have a TX power control that would compensate that. > > Are yo

[USRP-users] Delayed samples receiving, X310

2019-08-07 Thread Cherif Diouf via USRP-users
Hello guys, I have developed a custom RFNoC CE connected to one radio core of the X310. The core will act as receiver and provide samples to my CE for further processing (Antennas-> RX frontend + noc_radio_core -> custom CE). However, I would like the radio core to start sampling and providing da

2019-08-07 Thread Marcus Müller via USRP-users
Dear Paul, I'd recommend taking this to the USRP-users mailing list (in CC), since it's not really GNU Radio-related. Since that clock rate setting doesn't really "exist" until the device is operating, you can't query that from any program than the program currently using the USRP (but that progr

No, it doesn't have to, as I've explained: I don't know what A is, but if A is leading to saturation or even clipping, and 8 is, too, then you see no change in amplitude. Best regards, Marcus On Wed, 2019-08-07 at 12:41 +0430, hossein talaiee wrote: > Dear Marcus, > > I use the same signal for N

You can! If you're using GRC to design your GNU Radio system, it's the "Clock Rate" property of the UHD USRP Source / Sink blocks; if you're directly coding, you want to call set_clock_rate() before doing anything else, or supplying "master_clock_rate=184.32e6" with your device address. Best rega

[USRP-users] USRP B210 FPGA Amplify-forward

Hello, I am working with 2 B210 units trying to realize an out-of-band amplify-forward wideband relay. The signal flow is simple and was already implemented using the GNURadio blocks and associated UHD USRP drivers. The input signal is DCed to BB by one of the RF ends and additionally am
