MIL-STD-461G CE101, CE102: Conducted Emissions, Audio Frequency Currents and Radio Frequency...
MIL-STD-461G CE101 and MIL-STD-461G CE102 are military test standards that pertain to audio frequency currents and radiofrequency potentials for conducted emissions testing, respectively.
MIL-STD-461G CE101
MIL-STD-461G CE101 applies from 30 Hz to 10 kHz for power leads, including returns, that obtain power from other sources not part of the EUT for surface ships, submarines, Army aircraft (including flight line) and Navy aircraft. For equipment intended to be installed on Navy aircraft, this requirement is applicable only if the platform contains Anti-Submarine Warfare (ASW) equipment, which operates between 30 Hz and 10 kHz, such as Acoustic (Sonobuoy) Receivers or Magnetic Anomaly Detectors (MAD). For AC applications, MIL-STD-461G CE101 is applicable starting at the second harmonic of the EUT power frequency. This test procedure is used to verify that electromagnetic emissions from the EUT do not exceed the specified requirements for power input leads including returns.
Test Equipment
The test equipment shall be as follows:
Measurement receivers
Current probes
Signal generator
Data recording device
Oscilloscope
Resistor (R)
LISNs
Procedures
The test procedures shall be as follows:
a. Turn on the measurement equipment and allow sufficient time for stabilization.
b. Measurement system integrity check. Evaluate the overall measurement system from the current probe to the data output device.
(1) Apply a calibrated signal level, which is at least 6 dB below the applicable limit at 1.1 kHz, 3 kHz, and 9.9 kHz, to the current probe.
(2) Verify the current level, using the oscilloscope and load resistor; also, verify that the current waveform is sinusoidal.
(3) Scan the measurement receiver for each frequency in the same manner as a normal data scan. Verify that the data recording device indicates a level within ±3 dB of the injected level.
(4) If readings are obtained which deviate by
