RADIATION INTERFERENCE: Testing was done in accordance with ANSI C63.4-2003. 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 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 t…
