[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 the scripts from filter_tool, but the thing is that the filter is applied to the right of the center frequency, but also to the left, it is just mirrored having the center frequency as reference. I want to know if is there any possibility to elimitate the filter from the left size of the center frequency, or this is a result due to the existence of two FIR filters, each one applied to I and Q paramters. ___ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
[USRP-users] 2x RX/TX Transceiver
Hi there. I have a usrp device, namely B210 and i would like to know if it is possible to make a dual transceiver. The think is that i want to receive two different frequencies and transmit them on other two frequencies. In other words, i would like to make a repeater of two frequencies. I managed to do this repeater for one pair RX and TX/RX but i cannot do it for two pairs of frequencies. I tried something, but after i run i get this error: UHD Error: The receive packet handler failed to time-align packets. 1002 received packets were processed by the handler. However, a timestamp match could not be determined. Error: Receiver error ERROR_CODE_ALIGNMENT (Multi-channel alignment failed) I get this message because the two RX are working just in MIMO and can not be separated or what it means? Thank you very much and i wait for your answers. ___ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
