UHD_SIGGEN(1)

✨ UHD_SIGGEN(1) ✨

okay bestie, gather round, because today we're talking about uhd_siggen — the Signal Generator using UHD hardware, straight out of the User Commands chapter. this is the moment. 💅

---

🌸 SYNOPSIS 🌸

uhd_siggen: [options]

that's it. that's the whole vibe. you feed her options, she generates signals. 🦋

---

💖 DESCRIPTION 💖

so basically? it's a command-line signal generator application. no GUI, no fuss, just you and the terminal and your UHD hardware being iconic together. no cap. 🔥

---

🎀 OPTIONS 🎀

• -h, --help — show this help message and exit 🫶 (the classic "hello, what do you do" move, she loves to explain herself)
• -a ARGS, --args=ARGS — UHD device address args , [default=] — yeah the default is literally empty, that's not me being lazy, that's what it says 💀
• --spec=SPEC — subdevice of the UHD device, for when you gotta be specific about which one you're talking to, where appropriate
• -A ANTENNA, --antenna=ANTENNA — select Rx Antenna where appropriate 📡 (yes it says Rx, that's not a typo on my part, write it down)
• -s SAMP_RATE, --samp-rate=SAMP_RATE — set sample rate (bandwidth) [default=1000000.0] ⭐
• -g GAIN, --gain=GAIN — set gain in dB (the default is midpoint, so she picks for you if you don't)
• -f FREQ, --tx-freq=FREQ — Set carrier frequency to FREQ [default=mid-point] 🎯
• -x WAVEFORM_FREQ, --waveform-freq=WAVEFORM_FREQ — Set baseband waveform frequency to FREQ [default=0]
• -y WAVEFORM2_FREQ, --waveform2-freq=WAVEFORM2_FREQ — Set 2nd waveform frequency to FREQ [default=none] — yes she has a second waveform slot, she's multitalented 💜
• --sine — Generate a carrier modulated by a complex sine wave 🌊
• --const — Generate a constant carrier (the chill one, no drama, just vibes)
• --offset=OFFSET — Set waveform phase offset to OFFSET [default=0]
• --gaussian — Generate Gaussian random output ✨
• --uniform — Generate Uniform random output 🌈
• --2tone — Generate Two Tone signal for IMD testing 👑
• --sweep — Generate a swept sine wave 🧚
• --amplitude=AMPL — Set output amplitude to AMPL (0.0-1.0) [default=0.15] — keep it in that range, bestie, don't get feral
• -v, --verbose — Use verbose console output [default=False] — for when you want her to actually talk to you 🙈
