Measurement Uncertainty

Where relevant, the following measurement uncertainty levels have been estimated for tests performed on the EUT as specified in CISPR 16-4-2:

ANNEX A: EUT photograph

EUT photos are reflected in specialized prototype documents.

ANNEX B: METHODS OF MEASUREMENT

B.1 Generic methods of measurement

Two generic methods of measurement are applicable to verifying the performance of the receiving equipment in question. The conducted test methods shall be used for receivers with an external antenna connector. The radiated test methods shall be used for all other receivers. For both generic methods, two generators are needed. One provides the wanted signal, and the other the unwanted signal, or interferer (when required). The two signals are combined in such a way as to maintain isolation between the generators. It is necessary to provide calibrated attenuators for control of the individual levels; very often these will be built into the generators. Where the attenuators are external, cable lengths should be kept short to avoid cross-coupling effects. The tests require the audio output of the receiver to be measured. All tonal controls (user operated and/or preset, for example, vehicle specific equalizer, etc.) shall be set to provide a flat response during the testing.

B.2 Generic measurement set-up for radiated testing

Figure 1: Generic measurement arrangement for receivers with built-in or integral antennas. The setup includes two signal generators (one for the wanted signal, one for the unwanted signal), each connected to a variable attenuator. These are combined using a combiner (labeled 'C'). The combined signal is fed to a receiver under test, which is placed within a GTEM-cell. A measurement device is connected to the receiver to record the output.

The combiner shall be appropriate for the frequency range of the testing and shall be designed so as to prevent coupling between the two signal generators. Some test houses have experienced difficulties using hybrid combining networks at LF and MF. In such cases a resistive combiner may be appropriate, but care should be taken to ensure the coupling between the generators does not result in unwanted intermodulation products. Hybrid combiners are available for use at LF and MF and these usually give better performance than resistive combining networks. Signal generator 1 and signal generator 2 may be combined as a single item of test equipment. In this case either the RF signal or the baseband signal may be combined internally, as long as the signal at calibration point is equivalent to the signal generated in the setup according to figure 1.

The power levels of the two generators are measured at . For a 50 Ω system, when the power at is P W, the nominal field-strength E is given by:

E = √50 × P / h

where h is the height of the cell's septum above its floor in metres. The exact relationship between P and E should be obtained from the manufacturer of the cell. A Semi Anechoic Chamber (SAC) or Fully Anechoic Room (FAR) in compliance with CENELEC EN 55032 [1], table A.1, annex C and annex D may be used in place of a GTEM cell. In these environments, electrical connections from the receiver to the audio measurement device are permitted provided they can be shown not to disturb the electric field; ferrite cores and/or filters are required.

ANNEX D: GRAPH RESULTS

Figure 1: Unwanted emissions in the spurious domain (Radiated) (Set.5: 98MHz). This graph shows the frequency spectrum from 30 MHz to 1 GHz. The Y-axis represents the Level in dBμV/m, ranging from 0 to 50. The X-axis represents the Frequency in Hz, with markers at 30M, 50, 60, 80, 100M, 200, 300, 400, 500, 800, and 1G. A red line indicates the limit (CISPR32. Radiated Emission Class. B. QP 1.0m). The plotted blue line shows the measured emissions, which generally stay below the limit line. A note indicates a spike over the limit originates from the FM signal generator. Another note clarifies that the six highest emissions are not required as they are 10 dB or more below the limit.
