GR_PLOT_IQ(1)

🦋 gr_plot_iq — the "let me SEE my I&Q data" era 💖

okay bestie, so this is gr_plot_iq, a little User Command from the GNU Radio girlies. She plots complex binary I&Q data versus time. That's it, that's the whole vibe. ✨

🌸 NAME 🌸

gr_plot_iq — plot complex binary I&Q data versus time using GNU Radio

---

🎀 SYNOPSIS 🎀

gr_plot_iq.py: [options] input_filename

---

💅 DESCRIPTION 💅

So here's the tea, bestie. This one takes a GNU Radio complex binary file and literally displays the I&Q data versus time. Like, on your screen. Gorgeous. 😭💖

You can set the block size to specify how many points to read in at a time, and you can set the start position in the file. You have options. You have range. You have main character energy. 👑

Now — important — by default the system assumes a sample rate of 1, so in time, each sample is plotted versus the sample number. That's not a true time axis, that's just counting. If you want an actual real-deal time axis, set the sample rate (-R or --sample-rate) to the sample rate that was used when the samples were captured. Do that and the axis slays. Don't do that and it's giving "sample number," no cap. 🦋

✨ OPTIONS ✨

• -h, --help — shows this help message and dips. byee 👋
• -B BLOCK, --block=BLOCK — specify the block size, bestie. how many points we grabbing at once. [default=1000]
• -s START, --start=START — specify where to start in the file. pick your starting point, your origin story. [default=0]
• -R SAMPLE_RATE, --sample-rate=SAMPLE_RATE — sets the sampler rate of the data, so your time axis is actually real. [default=1.0] 🌈

ngl the --sample-rate one is the glow-up. default of 1.0 means you're just plotting against sample numbers, fr fr. set it properly and it's iconic.
