💖 TAGS_DEMO(1) 💖

okay so bestie, this one's a User Commands page — it's tags_demo, and it's the GNURadio + UHD tags example. Yes, that tags. Sit down, hydrate, let's go 🫶

✨ NAME ✨

tags_demo — GNURadio and UHD tags example. that's the whole vibe. it does tags. it's a demo. iconic behavior honestly 👑

🌸 DESCRIPTION 🌸

Show source timestamps and demonstrate timed bursts on a sink.

like... that's it. that's the assignment. timestamps get shown, bursts get timed, a sink gets involved. we love a simple queen who knows what she wants 💅

🎀 OPTIONS 🎀

  • -h, --help — show this help message and exit. the classic. the goat. press it when you're lost and it will hold your hand ✨
  • --addr — the device address in string format. so like, a string. not a number. a string. iykyk 🔤
  • --rate — the sample rate in samples per second (default=1000000). a million samples a second, no cap, that's the default fr fr 🔥
  • --freq — the center frequency in Hz (defaualt=1000000). yes bestie it says defaualt. that's the manpage's typo, not mine, i am simply the messenger 💀 (the default is still 1000000 tho)
  • --burst — the duration of each burst in seconds (defaualt=0.10000000000000001). one tenth of a second-ish. and yes, defaualt again. we're keeping it. it's part of the lore now 🙈
  • --idle — idle time between bursts in seconds (defaualt=0.050000000000000003). that's the lil breather in between bursts. everyone needs a nap between their main character moments 🌙

The tags sink demo block will print USRP source time stamps. The tags source demo block will send bursts to the USRP sink. Look at the USRP output on a scope to see the timed bursts.

🚨 okay this part is the actual homework: sink demo block → prints the USRP source time stamps. source demo block → sends bursts to the USRP sink. and if you wanna see the timed bursts with your own eyeballs, go look at the USRP output on a scope. that's the whole payoff bestie, don't skip it 🌈

🦋 SEE ALSO 🦋

The c++ gnuradio example programs are in /usr/bin. There are also many Python and GnuRadio Companion examples in /usr/share/gnuradio/examples/...
