All antenna types were evaluated. Because the upper band-edge coincides with a restricted band, band-edge compliance for the upper band-edge was determined using the radiated method. The radiated field strength of the fundamental emission was measured as an absolute field strength. The lower band-edge compliance was determined using the conducted marker-delta method in which the radio frequency power that is produced by the EUT is at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of desired power. 7.5.1.2 Measurement Results Band-edge compliance is displayed in Table 7.5.1.2-1 and Figure 7.5.1.2-1.

The EUT was rotated through 360° and the receive antenna height was varied from 1m to 4m so that the maximum radiated emissions level would be detected. For frequencies below 1000MHz, quasi-peak measurements were made using a resolution bandwidth RBW of 120 kHz and a video bandwidth VBW of 300 kHz. For frequencies above 1000MHz, peak and average measurements were made with RBW and VBW of 1 MHz and 3 MHz respectively. The average emissions were further corrected by applying the duty cycle correction of the EUT for comparison to the average limit. Each emission found to be in a restricted band as defined by section 15.205 was compared to the radiated emission limits as defined in section 15.209. 7.5.3.2 Duty Cycle Correction For average radiated measurements, using a 27% duty cycle, the measured level was reduced by a factor 11.37dB. The duty cycle correction factor is determined using the formula: 20log (27/100) = -11.37dB. A detailed analysis of the duty cycle timing is provided in the Theory of Operation accompanying this report. 7.5.3.3 Measurement Results Radiated spurious emissions found in the band of 30MHz to 25GHz are reported in the tables below.
