Custom Demodulation and Algorithm Development: If you're developing a new receiver algorithm, a signal classifier, or a custom demodulation chain, you need real-world I/Q data captured from actual RF signals—not simulated data from a model. The I/Q option captures up to 8 million I/Q sample pairs per acquisition at bandwidths up to 255 MHz (with appropriate bandwidth option), providing the raw material for algorithm development and validation. Export to MATLAB or CSV, process with your custom code, and iterate.
Interference Analysis and Signal Recording: When an intermittent interference event occurs, the I/Q option captures the complete baseband representation of that event for detailed offline analysis. Combined with the analyzer's trigger capabilities (free run, external, power, frequency mask template), you can set up the analyzer to capture I/Q data only when the interference appears—building a library of interference signatures for root-cause analysis.
Radar Pulse Analysis: I/Q capture preserves the full amplitude and phase information of radar pulses, enabling detailed pulse characterization including intra-pulse modulation (chirp linearity, phase coding), pulse-to-pulse stability, and PRF jitter. The time-domain I/Q display shows pulse shape directly, while FFT analysis reveals spectral content within individual pulses.
Machine Learning Training Data: RF signal classification using neural networks requires large labeled datasets of I/Q samples from real signals. The I/Q option provides a calibrated, high-dynamic-range capture front-end for building these datasets across the full 2 Hz to 40 GHz frequency range.
