Neel, I updated to: UHD_3.14.1.1-0-g0347a6d8 as well as v3.7.13.5 for GR, still the same issues.
It almost feels like some sort of double/float mismatch somewhere since the alignment is so close to being right. ________________________________ From: Neel Pandeya <[email protected]> Sent: Monday, September 30, 2019 11:19 AM To: Jason Matusiak <[email protected]> Cc: usrp-users <[email protected]> Subject: Re: [USRP-users] next pps issues with TwinRX Hello Jason: We'll look into this and get back to you shortly. If you get a chance, could you please try it with the tagged UHD 3.14.1.1 ? Which version of GNU Radio are you using? --Neel Pandeya On Mon, 30 Sep 2019 at 10:10, Jason Matusiak via USRP-users <[email protected]<mailto:[email protected]>> wrote: We are having another issues with our TwinRXs. A co-worker has been trying to get this to work for a while, but has had no luck with the PPS timing. Here is the notes: We are running UHD_3.14.1.HEAD-12-g5f75f73f. The setup is a single X310 (revision: 11, revision_compat: 7) with two TwinRX boards. The device gets Ref/PPS from an Octoclock. The attached script has a hard-coded IP address and clock rate. It works for other X310s with UBX/SBX daughter boards as well as the E320. Good results are (note line 5 below): Synchronizing Radios to Reference Signals Checking PPS synchronization next_pps from 1569851984.633563 is 1569851985.000000 Setting time for radio `gr uhd usrp source`: 2019-09-30 09:59:45 PPS alignment PASSED!: [1569851986.0, 1569851986] All radios are Synchronized Bad results are: Synchronizing Radios to Reference Signals Checking PPS synchronization next_pps from 1569851508.136703 is 1569851509.000000 Setting time for radio `gr uhd usrp source`: 2019-09-30 09:51:49 PPS alignment mismatch: [1569851509.9999995, 1569851509] Any thoughts of why this might be happening? _______________________________________________ USRP-users mailing list [email protected]<mailto:[email protected]> http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com<https://urldefense.proofpoint.com/v2/url?u=http-3A__lists.ettus.com_mailman_listinfo_usrp-2Dusers-5Flists.ettus.com&d=DwMFaQ&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=W_MQLyUWPXWHfsF4mr51mTMqpeO4RbBBLexficV9DG8&m=VzsjpGSylp7F9peAKPOcnLbFzmAh8CNVnwzwket3hCo&s=_gOstnMMEDkfFbD1tcNsLqzHaSnMGcIjP7W9NVzbH6M&e=>
