4.1 General provisions
The test methods, procedures, test apparatuses, and grades specified in this series of standards are used to determine whether ESA is responsible for narrowband radiation electromagnetic energy The interference characteristics of electrical harassment provide the basis for the agreement between the vehicle manufacturer and the component supplier. Some ESAs are very sensitive to some of the characteristics of electromagnetic disturbance signals (such as frequency, severity, coupling, or modulation type) Some are more sensitive to modulated RF signals than unmodulated signals because high frequency disturbances may be demodulated by semiconductor devices; unmodulated signals may Will lead to continuous fluctuations in voltage and other characteristics, and amplitude modulation signal is demodulated after the low-frequency fluctuations in the signal may be mistaken by the electronic device is Useful signal (such as speed information), then the device under test (DUT) is more vulnerable to serious interference. A single test method may not reflect all the information about DUT immunity. Therefore, the use of this series of standards should be pre-determined appropriate Test conditions, select the corresponding part of GB/T 33014, define the performance indicators of the DUT.

If the sensitivity threshold of the DUT is close to the selected test level, the frequency step near the sensitive frequency point should be appropriately reduced to determine the sensitivity Degree threshold.
4.8 Test the definition of harsh rating
The severity level should be defined by frequency range. Functional characteristics Classification (FPSC) is defined in Appendix A. Whether using alternative methods or Closed-loop test, regardless of the test signal is the use of unmodulated signal or amplitude modulation, pulse modulation signal, test harsh rating (electric field, current, Voltage or power) are based on the equivalent rms value of the unmodulated signal. Both the alternative method and the closed-loop method adopt equal peak test levels for unmodulated and amplitude modulated signals (see Appendix B). The average power of the amplitude modulated signal The relationship between the average power of the unmodulated signal is given by. PAM =
2 m2
2 (1 m) 2
PCW
Where.
PAM --- the average power of the AM signal;
PCW --- the average power of the unmodulated signal;
M --- modulation depth (0 ≤ m ≤ 1).
For example, a test severity of 20 V/m means that the peak value of the unmodulated test signal and the modulation test signal is 28 V/m. 4.9 Test signal quality
The test signal quality is shown in 5.4.
5 test equipment
5.1 Analog load
The DUT should be connected to the actual sensor and load.
If some loads and sensors are not easy to use, you can use an analog load equivalent to their electrical characteristics, but should ensure that the analog load is complete The test frequency range has the same impedance characteristics as the actual device.

6.2 Test methods
6.2.1 General
The following methods are used for the relevant part of GB/T 33014.
6.2.2 Alternative method
Use forward power as the reference parameter for calibration and testing. The specific test level (electric field, current, voltage or power) should be measured before the test set. Test the DUT by applying a test signal to a predetermined calibration value in the test plan. Calibration and testing of forward power during the test and The reflected power should be recorded.
The forward power required for the test signal can be derived from the following equation according to the calibration value. Pfor = Pforcal
Ltss
Lcal

In the actual test, the test level (electric field, voltage, current or power) is measured with a calibration device and fed back to the signal generator in order to increase Or reduce the test level until a predetermined level is reached.
6.3 Calibration
Should be calibrated separately according to the requirements of each test method. The untested sine wave should be used to determine the test level relative to the frequency. each Sub-calibration methods and results should be recorded in the test report. 6.4 DUT immunity measurement
