## What it is
QSpectrumAnalyzer is a PyQtGraph-based GUI spectrum analyzer for software-defined radio devices. It wraps multiple measurement backends such as soapy_power, hackrf_sweep, rtl_power, rtl_power_fftw, and rx_power to visualize RF spectra.

## Use cases
- visualize RF spectrum from an RTL-SDR dongle
- wideband spectrum monitoring with HackRF sweep mode
- near real-time spectrum measurement with soapy_power
- compare signal strength across frequency bands
- analyze interference in the 2.4 GHz band
- capture FFT waterfall plots from SDR hardware

## When to choose
- you have an SDR device (RTL-SDR, HackRF, Airspy, LimeSDR, etc.) and want a ready-made GUI spectrum analyzer
- you want a single tool that supports multiple SDR backends
- you need wideband sweeping with hackrf_sweep

## When to avoid
- you need a headless or scriptable spectrum measurement pipeline
- you require real-time demodulation or audio listening rather than spectrum visualization
- you need a web-based or remote spectrum analyzer
