Advanced mode: beginner workflow cards are hidden and not in play. All charts and full controls remain visible for manual setup, acquisition, measurement, analysis, PCB remediation review, and verification.
Configure Baseline setup and compliance model Set standard, detector, band, calibration, units, and FFT or sweep method before acquisition.
Scan Fast signal discovery Use live FFT or sweep stepping to surface peaks, masks, and candidate emissions quickly.
Explain Interpret trends and failure drivers Correlate settling, spectrum evolution, time-domain activity and violation context to explain likely root causes and export evidence.
Fix · PCB EMC Autopilot Open the integrated PCB workspace, preview remediation and apply engineer-approved changes Rank PCB EMC findings, inspect evidence and expected gain, then preview the exact geometry before an engineer-approved change.
Verify Reanalyse and release decision Rerun EMC intelligence after the approved PCB change, compare before/after evidence, and support the technical-file release decision.

FFT Processing Pipeline (EMI Receiver Equivalent)

The advanced FFT options replicate the signal processing stages used in digital EMI receivers defined in CISPR 16. The processing chain converts time-domain waveform samples into calibrated spectral measurements with defined Resolution Bandwidth (RBW) and detector behavior.

Hover, focus, or click a stage to see details.

How the Advanced FFT Options Map to This Pipeline

Smooth ? Applies moving-average smoothing across adjacent FFT bins to reduce spectral jitter and improve display readability while preserving overall signal power.
PSD + RBW ? Converts the FFT spectrum to Power Spectral Density (PSD) using window ENBW correction, then integrates PSD over the selected resolution bandwidth (RBW) to provide accurate broadband noise power and Vrms measurements.
Power Bin Grouping ? Groups adjacent FFT bins and sums their power to synthesize a wider resolution bandwidth (RBW), improving broadband noise estimation and reducing sensitivity to individual FFT bin variations.
Gaussian IF ? Applies a Gaussian-shaped digital IF filter to emulate the response of analog CISPR EMI receivers, reducing spectral leakage while providing accurate resolution bandwidth (RBW) measurements.
CISPR Gaussian IF (ENBW Compensated) ? Applies a Gaussian IF filter with Equivalent Noise Bandwidth (ENBW) compensation to preserve accurate noise power and unbiased amplitude measurements while maintaining the target CISPR resolution bandwidth (RBW).
Gaussian IF Power Area Compensated ? Applies a Gaussian IF filter with amplitude compensation to preserve total signal power after filtering while maintaining the target CISPR resolution bandwidth (RBW).
Hybrid PFB CISPR IF ? Uses a hybrid FIR polyphase filter bank (PFB) to reduce spectral leakage and scalloping loss, improve channel isolation and dynamic range, and synthesize a CISPR-compliant IF response.
