2016-12-23 Thread Michael Skaggs
Hi all, We're currently working with a BasicTX daughterboard attached to a N210 USRP. We are using both outputs of the BasicTX in quadrature (I on one channel, Q on the other). The problem we are running into is that the output power of the BasicTX board seems very low. Looking at it on an

[Discuss-gnuradio] Higher Accuracy Metadata Header?

2016-04-21 Thread Michael Skaggs
I'm trying to time/sample synchronize RF recordings with two B200minis. I am using the detached Metadata File Sink in GRC. Both recordings are at 30MSps and both B200mini boards are synchronized to the same 1PPS signal. My issue is this, when I extract the data from the Metadata header file, the

[Discuss-gnuradio] 1PPS Synchronization - File Meta Sink Data

Hi all, I'm doing a simple RF recording with a B200mini synchronized to an accurate GPS 1PPS. I'm attempting to determine which samples(most importantly the first one) fall on a 1PPS pulse. I'm using the File Meta Sink block in GRC to try and extract information from the recording. When I read

[Discuss-gnuradio] B200mini and Raspberry Pi 2 Connectivity

2016-02-24 Thread Michael Skaggs
Hello all, After sorting out my power issues with the B200mini (it required a dual USB to 3.0 mini cable, due to browning out the single USB 3.0 connection), I'm now trying to connect my B200mini to a Raspberry Pi 2. I was excited when I found that Raspbian has a gnuradio and gnuradio-dev
