Subject: | Re: [Discuss-gnuradio] Using two TwinRX in one x310 |
Date: | Tue, 4 Jul 2017 08:35:06 +0100 |
Hello,
This may be an usrp-users question, but I can’t seem to get approved for that list. Is it possible to use two TwinRX boards (4 channels) in a X310? As far as I can tell you need 4 DDCs, but only two are available by default.
A followup: why is it that TwinRX connection type is reported as ‘Connection Type: II’ for channel 0 QQ for channel 1.
Finally, I have a twinrx and a UBX board in one X310. Trying to run all 3 RX at the same time I get:
UHD Warning:
[X300 Radio] Requesting invalid sampling rate from device: 100 MHz. Actual rate is: 200 MHz.
thread[thread-per-block[0]: <block gr uhd usrp source (1)>]: RuntimeError: Conflicting tick rates: One neighbouring block specifies 2e+08 MHz, another 1e+08 MHz.
Thanks
