20 Unwanted Emissions outside Restricted Bands This section was only done where compliance with limits for restricted bands, in both restricted and non-restricted bands, could not be achieved or was not required. The following bands were investigated: MHz GHz.. Measurement method Since peak power measurements were made using a RMS detector, the same detector will be used for unwanted emissions. The unwanted emissions shall be at least 3dB lower than the wanted emission. Testing in the bands immediately adjacent to the wanted band may be done with lower than stated RBW provided the power is integrated over the required bandwidth. First, establish a reference level by using the following procedure for measuring the peak power level in any khz bandwidth within the fundamental emission: The measurement procedure for determining the reference level laid down in section of KDB55874 is identical to measurement method employed in section, so maximum values Peak Marker Values obtained in section. shall be used. The Maximum out of Band Emissions values are determined by subtracting 3dB from the values obtained in section and detailed in table 9 which gives the resultant maximum permitted out-of-band emissions levels detailed in table : Next, determine the power in khz band segments outside of the authorized frequency band using the following measurement: Measurement Procedure - Unwanted Emissions Set RBW = khz. Set VBW = 3 khz. Set span to encompass the spectrum to be examined. Detector = peak. Trace Mode = max hold. Sweep = auto couple. llow the trace to stabilize (this may take some time, depending on the extent of the span). SC_TR_5_B Page 2 of 29
