12 7.3 Out of band radiated emissions above 40 GHz up to 220 GHz General This test was performed to measure field strength of spurious emissions from the EUT. Specification test limits are given in Table Frequency, GHz Table Power density emission limits Power density at distance pw/cm2 Distance, m Field strength db(nv/m)*, peak Field strength db(nv/m)*, average ** 93.5** *** *** **** **** **** **** ** 95.8** **** **** *- The limit is provided in average values. **- The field strength was calculated as follows: [20 log (10 2 x Px1207c) + 120] db(µv/m) ***- The limit for 0.5 m test distance was calculated using the inverse square distance extrapolation factor as follows: LimS2 = LimS log (S1/S2), where S1 and S2 standard defined and test distance respectively in meters; ****- The limit for 0.08 m test distance was calculated using the inverse square distance extrapolation factor from the point of measurement to the edge of far field as follows: LimS3 = LimS log (S2/S3), where S2 and S3 the edge of far field boundary and test distance respectively in meters Test procedure for spurious emission field strength measurements The EUT was set up as shown in Figure 7.3.1, energized and the performance check was conducted The specified frequency range was investigated with antenna connected to spectrum analyzer/ EMI receiver. To find maximum radiation the turntable was rotated 360 0, the measuring antenna height was changed from 1 to 4 m, its polarization was switched from vertical to horizontal The test results are shown in the associated plots.

Verdict Pass Pass Pass NOTE: Spurious investigation was performed with EUT set to produce unmodulated carrier at the lowest, middle and highest carrier frequency and the peak values were measured. Then the EUT was configured to produce the normally modulated sweep and average values were measured at the specific spurious frequencies.
