💖 UHD_SIGGEN_GUI 💖

okay bestie, welcome to uhd_siggen_gui — it's the GNU Radio signal generator that uses UHD hardware, and it's lowkey iconic. this is section 1 of the User Commands manual, and yes we're reading the whole thing together, no skimming 🫶

✨ NAME ✨

uhd_siggen_gui — a GNU Radio signal generator that drives UHD hardware. that's it, that's the vibe 💅

🌸 SYNOPSIS 🌸

uhd_siggen_gui: [options]

🦋 DESCRIPTION 🦋

so basically it's a GUI (graphical user interface, bestie) that lets UHD-supported hardware do the most: it turns your hardware into a signal generator ✨ like, your radio is now a whole signal-making main character.

🎀 OPTIONS 🎀

here's the full menu of flags, every single one, no notes:

  • -h, --help — show this help message and then exit, so you're never lost 💖
  • -a ARGS, --args=ARGS — UHD device address args, [default=]
  • --spec=SPEC — the subdevice of the UHD device, where that's appropriate
  • -A ANTENNA, --antenna=ANTENNA — pick the Rx Antenna where appropriate 📡
  • -s SAMP_RATE, --samp-rate=SAMP_RATE — set the sample rate (aka bandwidth), [default=1000000.0]
  • -g GAIN, --gain=GAIN — set the gain in dB (the default is the midpoint, so it's giving balanced)
  • -f FREQ, --tx-freq=FREQ — set the carrier frequency to FREQ, [default=mid-point]
  • -x WAVEFORM_FREQ, --waveform-freq=WAVEFORM_FREQ — set the baseband waveform frequency to FREQ, [default=0]
  • -y WAVEFORM2_FREQ, --waveform2-freq=WAVEFORM2_FREQ — set the 2nd waveform frequency to FREQ, [default=none]
  • --sine — generate a carrier modulated by a complex sine wave 🌊
  • --const — generate a constant carrier
  • --offset=OFFSET — set the waveform phase offset to OFFSET, [default=0]
  • --gaussian — generate Gaussian random output 🎲
  • --uniform — generate Uniform random output
  • --2tone — generate a Two Tone signal for IMD testing
  • --sweep — generate a swept sine wave
  • --amplitude=AMPL — set the output amplitude to AMPL (between 0.0 and 1.0), [default=0.15]
  • -v, --verbose — use verbose console output, [default=False]
ngl, if you're not sure which waveform flag you want, that's a whole mood — but the list above is the entire menu, fr fr.
