radio-frequency-emissionslisted

Use when you must plan and check the DO-160 section 21 radio frequency emission test of airborne equipment: convert the measured conducted emission amplitude from volts to dBuV and the radiated emission field to dBuV/m at the antenna, classify the equipment installation category, apply the CE102 conducted emission limit curve and the RE102 radiated emission limit curve for the category, compute the emission margin at each frequency, find the worst case frequency, and judge the equipment pass or fail for the EMC qualification. Produces the emission margin, the worst case frequency, and the pass or fail verdict that gate the DO-160 EMC qualification. Trigger: radio frequency emissions, DO-160 section 21, conducted emissions, radiated emissions, CE102, RE102, emission limit, emission margin, dBuV, dBuV/m, EMC qualification.

# Radio Frequency Emissions (avionics/do160/radio-frequency-emissions) Use when the task is planning and checking the DO-160 section 21 equipment emission test of airborne equipment: CE102 conducted emissions over 10 kHz to 10 MHz and RE102 radiated emissions over 2 MHz to 18 GHz. This leaf converts measured amplitudes into the dBuV and dBuV/m scales, applies the reference-only typical limit model for the installation category, computes the emission margin at every frequency, finds the worst case frequency, and returns the pass or fail verdict that gates the EMC qualification. It is implemented in pure Python, stdlib only. The immunity counterpart (DO-160 section 20, the radio-frequency-susceptibility leaf) owns the radiated and conducted susceptibility tests of the same equipment; this leaf is strictly the emission side, section 21. ## Domain quick reference - Conducted emission level: dBuV = 20 * log10(V_uV), with V_uV the measured amplitude in uV (volts * 1e6). Anchors: 1 V is 120 dBuV, 1 mV is 60 dBuV, 1 uV is 0 dBuV. dbu_v_from_volts and volts_from_dbu_v convert both ways. - Radiated emission level: dBuV/m = 20 * log10(E_uV/m), with E in V/m. Anchor: 1 V/m is 120 dBuV/m. dbu_v_per_m_from_v_per_m converts one way; the RE102 antenna measurement is then expressed in dBuV/m. - CE102 limit (reference-only typical, NOT the normative RTCA curve): piecewise constant over the test band, 78 dBuV below 100 kHz, 60 dBuV from 100 kHz to 2 MHz, 70 dBuV from 2 MHz to 1
