Section 15.35(b) specifies the use of an average detector in this band. In addition, the peak level of an emission shall not exceed the average limit by more than 20 dB using a minimum resolution B=bandwidth (RBW) of 1 MHz and minimum Video Bandwidth (VBW) OF 1 MHz. The following procedure is designed to determine if there are any spurious emissions from the local oscillator within the band of interest along with any additional spurious emissions caused by other circuitry within the device. 1) Determine the frequency of the peak emission: Start Frequency 11.7 GHz Stop Frequency 12.2 GHz RBW equal to or greater than 1 MHz VBW equal to or greater than 1 MHz Detector Function Peak Maximize the emissions with regards to device orientation, antenna polarization, and antenna height. Sweep the band using Max Hold for a minimum of 2 minutes. Record this frequency for measuring the peak emission. In addition record the frequency of other spurious emissions noted. 2) Determine the peak level of the emission: Center Frequency Set to the frequency determined in Step 1 RBW Equal to or greater than 1 MHz VBW Equal to or greater than 1 MHz Detector Function Peak Measure the value of the peak emission using Max Hold for a minimum of 2 minutes. This can be done at zero span or a frequency span where the analyzer does not show a “Measurement Uncalibrated” message. Record the peak value. If the peak measurement is compliant with the average limit an average measurement is not necessary. If the peak value exceeds the average limit by less than 20 dB proceed to Step 3. 3) Determine the average level of the emission: Center Frequency Set to the frequency determined in Step 1 Span Zero RBW Equal to or greater than 1 MHz VBW Equal to or greater than 10 Hz Detector Function Peak This measurement uses video averaging and must be done in Linear mode. The analyzer Reference Level is adjusted so that a signal is clearly visi…
