6.6 In addition to this standard are recommended, the rest are mandatory. This standard is identical with the International Special Committee on Radio Interference publication IEC /CISPR12.2009 "Vehicles, boats and internal combustion engines without Radio disturbance characteristics Limits and methods of measurement for the protection of the outside receiver "(Version 6.1). Taking into account the usefulness of national standards, deleted Content Appendix H "duration of the project," the.
This standard is GB 14023-2006 "Vehicles, boats and internal combustion engine driven devices - Radio disturbance characteristics - Limits and square Amendment Act ".
This standard applies to the frequency range of 30MHz ~ 1000MHz.
Changes in this major technical standard GB 14023-2006 made as follows. a) the name of the standard "vehicles, boats and means of radio disturbance characteristics - Limits and methods of measurement by the internal combustion engine-driven" to "car Vehicles, boats and internal combustion engines - Radio disturbance characteristics Limits and methods of measurement for the protection of "outside the car receiver. b) Add 3.6 "outdoor test site (OTS)" and 3.16 "battery" is defined.
c) no longer follow the original standard test method, this standard requires the use of a peak, quasi-peak and average detector test vehicle for two cases Measurement, namely "the power and the engine is not running (KeyOn, Engine-0ff)" and the "engine running (Engine-Run- ning) ". At the same time, changes to the compliance determination flowchart. d) 4.2 "peak and quasi-peak detector limits" to replace the original "Broadband emission" limit. e) 4.3 "average detector limits" instead of the original "narrow-band emission 'limits. f) set new spectrum analyzers and scanning receiver parameters.

Equivalent capacitance for - i) B "whip antenna (monopole antenna) performance equations and whip antenna matching characteristics of the amplifier to delete the original standard appendix Behalf of the law. "
j) amend Appendix G for determining the applicability of the standard flow chart. This standard replaces GB 14023-2006 "Vehicles, boats and internal combustion engine driven devices - Radio disturbance characteristics - Limits and methods of measurement." This standard by the National Standardization Technical Committee on Radio Interference (SAC/TC79) and focal points. This standard is drafted by. Shanghai Electric Apparatus Research Institute, China Automotive Technology and Research Center. Participated in the drafting of this standard.

4 disturbance limits
4.1 determine the compliance of the vehicle/boat/device based limits
30MHz ~ 1000MHz frequency range, the vehicle/boat/device shall conform to the following two conditions. --- The average value, mode of the vehicle/boat/device. "The power and the engine is not running (Key-On, Engine-Of)" (see 22.214.171.124), --- Mode peak or quasi-peak limits, vehicle/boat/device. "The engine is running (Engine-Running)" (see 126.96.36.199) Limits given in this standard takes into account the uncertainty.
Figure provides a method of determining compliance 1.
Since a peak detector measurement value is always greater than or equal to the quasi-peak and average detector measured data, and the peak limits applicable is always higher than or equal to Quasi-peak and average limits. Single detector test measuring method enables simplified, and accelerate the progress of the test. b The flowchart applies to each individual test frequencies, for example, only a few points need to exceed the limit of frequency respectively quasi-peak detector and the average detector Re-measurement.
Figure 1 flowchart of a method of determining compliance with
4.2 peak and quasi-peak detector limits
When measuring 10m antenna distance, use peak or quasi-peak detector measuring the emission limits in Figure 2 tables and curves. measuring , Only you need to select a bandwidth of 2 in FIG. In order to more accurately determine the limits, the limits given by the formulas in Figure 2 should be used. If the measurement A distance of 3m, the limit should be increased 10dB. 1)
1) When using different detector models and measuring the distance, if the measurement result of conflict, the provisions of this standard to the quasi-peak detector and 10m measuring distance Measurement results shall prevail.
Limit LBW [dB (μV/m)] --- bandwidth detector and frequency f (MHz) function Note 1. provided with driving motor vehicles, see 5.3.2.
Note 2. The peak measurement, see 5.4.
Note 3. An accumulation of empirical data, the correction coefficient between 120kHz bandwidth and a quasi-peak and peak measurements is 20dB. Figure 2 antenna measured at a distance of 10m harassment limits (peak and the quasi-peak detector) 4.3 average detector limits
Antenna measurement distance of 10m, using the average detector measurement of emission limits shown in Figure 3. It does not contain more than the operating frequency of 9kHz Electronic oscillator vehicle/boat/device may be regarded as the average meet the requirements without the need for the average detector test. In line with GB/T 18655 The average vehicle emission requirements/boat/device provisions of Chapter 5, is also considered to meet the requirements of the average of the limits specified in this section, no longer into Step measurement.
If the antenna measurement distance is 3m, the limit should be increased 10dB. Appendix D CISPR16-2-3 explained CISPR average detector and comply CISPR16-1.1999 average value detector the difference. Both detectors can be used in this standard, as pulse repetition rate of the internal combustion engine is higher than 10Hz. Note. For a 6.4 type certification tests, you can use an alternative method, this alternative method is based on standards of other countries, can be adjusted on the details. This An alternative type approval test for the receiver can be installed by car/boat/device. If the average value according to GB/T 18655 Test Method for Vehicle Detector to measure the transmitted signal strength of the car/boat/radio antenna installed on the device is lower than in the 76MHz ~ 108MHz frequency range 20dB (μV) (10μV), the car/boat/device can be considered in line with the average radiation emission limits without the need for further measurements.

5.1 Measuring Instruments
Measuring instruments shall comply with GB/T 6113.101 requirements, manual or automatic frequency scanning may be used. Note. Spectrum analyzers and scanning receiver is particularly suitable for disturbance measurements. For peak detector the same bandwidth, spectrum analyzers and scanning receivers squarewave Peak type shown greater than quasi-peak. Since the peak detector faster than the quasi-peak detector scanning speed, so emission measurement using a peak detection easier. When using the quasi-peak limit, in order to improve efficiency may also be measured using a peak detector. Any of the peak value is equal to or exceeds the test When the test limit, the quasi-peak detector remeasured.
5.1.1 Spectrum Analyzer parameters
Shall be in accordance with CISPR frequency band and detection methods used to adjust the scanning speed of the spectrum analyzer. The maximum scan rate shall comply with the CISPR16-2-3 requirements.
Select the appropriate spectrum analyzer bandwidth, so that the noise floor is lower than the limit of at least 6dB. NOTE. In order to achieve 6dB below the limit of noise floor requirements, you can use the preamplifier between the antenna and spectrum analyzer. Recommended scanning time and bandwidth are shown in Table 1 below.
