PRODUCT CLASSIFICATION
Review unique products to determine the appropriate standards that must be followed.
Commercial floor cleaner capable of autonomous operation
Electric ride-on mower that did not contain a fuel-powered motor
Portable medical device with some use in aviation settings
FAR-FIELD TESTING
Characterize the general performance of a system.
Collect data at 3 meters in an anechoic chamber with a logarithmic periodic antenna
Anticipate problems without having to pay for extra chamber time
Roughly locate sources of unintentional radiators for further testing
LAB TEST PREPARATION
Collect and catalog necessary materials prior to laboratory testing to maximize utility of limited chamber time.

ROOT CAUSE ANALYSIS
Use near-field scans to trace failing frequencies from point of emission to primary source and determine the most effective mitigation strategies:
Noise peaks amplified by enclosure gaps
High-order oscillator harmonics
Emissions radiating from a signal line but originating from elsewhere in the system
LAB TESTING OVERSIGHT
Maximize value from laboratory chamber testing with strategies developed over years of experience.
Compile scan lists to show experimental progression
Prioritize higher-energy and/or narrow-band peaks
Ensure every test either establishes a ground truth or alters as few variables as possible
