Import Tips
• Provide frequency range specs and block diagrams proving spectrum analysis function to confirm 9030 classification
• Label assemblies clearly as 'for spectrum analyzers only' to prevent misclassification as general RF boards
• Watch for radiation detection components that might trigger alternative ionizing radiation headings
