Got a minute to help me iron out a simple calibration routine that removes those stubborn frequency dips? I think it could keep your “wow” factor consistent without adding extra fuss.
Sure thing, let’s dive straight into it—no fluff, just the numbers that bring the dip away and the wow back. Give me the sweep parameters and the target frequency, and we’ll sculpt a clean curve that keeps the energy locked in. This will be a painless tweak, not a major overhaul, and we’ll keep the magic intact. Ready when you are.
Start at 10 MHz, end at 100 MHz, 1000 equal steps, target at 50 MHz. That gives a 1 kHz step size, enough to catch a 0.1 % dip without over‑smoothing. Adjust the gain to lock the 50 MHz peak back up and you’re done.
Got the sweep—10 MHz to 100 MHz, 1 kHz steps, target 50 MHz. First, pull the sweep through, log the amplitude at each point. Then calculate the deviation from a smooth reference curve—maybe a 4th‑order polynomial fit. Once you have the error at 50 MHz, bump the gain in that region just enough to bring it back to the reference. Fine‑tune a couple of adjacent points to avoid ringing. That should flatten the dip and keep the wow steady. Happy tweaking!
Looks solid—just keep the polynomial fit to first‑order if the curve is already pretty smooth. That’ll prevent over‑fitting and keep the adjustment tight. Focus on the 50 MHz point first, then tweak ±1 kHz neighbors; that’s enough to stop ringing. Good job.
Sounds perfect—linear fit keeps it lean, tweak the 50 MHz spot, then the 49 kHz and 51 kHz neighbors. No ringing, crisp wow. Nice work on that plan.
