Use a peak detector. - Do not use the Max Hold function. Rather, use the view button to capture the emission. - Measure the maximum width of the emission that is 26 dB down from the peak of the emission. - Compare this with the RBW setting of the analyzer. - Readjust RBW and repeat measurement as needed until the RBW/EBW ratio is approximately 1%. Test Results Refer to spectrum analyzer plots below. On the LOW channel, occupied bandwidth measurements were made for three data rates: 6 Mbps 24 Mbps 54 Mbps Measurement results (and theory) indicate occupied bandwidth is independent of data rate for this type of OFDM modulation. Occupied bandwidth for MID and HIGH channel were performed at 24 Mbps only. power injector Radio outdoor unit (ODU) 6 dB Agilent 4440A analyzer AC to 48 VDC AC mains Cisco Systems UNII Transceiver w/ External Antennas FCC ID: LDK102047P page 4 of 42 Occupied Bandwidth, 5745 MHz: LOW channel modulation Rate 6 Mbps Cisco Systems UNII Transceiver w/ External Antennas FCC ID: LDK102047P page 5 of 42 Occupied Bandwidth, 5745 MHz: LOW channel modulation rate 24 Mbps Cisco Systems UNII Transceiver w/ External Antennas FCC ID: LDK102047P page 6 of 42 Occupied Bandwidth, 5745 MHz: LOW channel modulation rate 54 Mbps Cisco Systems UNII Transceiver w/ External Antennas FCC ID: LDK102047P page 7 of 42 Occupied Bandwidth, 5785 MHz: MID channel modulation rate 24 Mbps Cisco Systems UNII Transceiver w/ External Antennas FCC ID: LDK102047P page 8 of 42 Occupied Bandwidth, 5805 MHz: HIGH channel modulation rate 24 Mbps Cisco Systems UNII Transceiver w/ External Antennas FCC ID: LDK102047P page 9 of 42 15.407(a) Peak power measurement Test equipment Agilent 4440A spectrum analyzer 6 dB attenuator coaxial cable (1.3 dB loss at 5.8 GHz) Test Set-up Refer to Figure 1. Test limits 15.407(a) (3) For the band 5.725-5.825 GHz, the peak transmit power over the frequency band operation shall not exceed the lesser of 1 W or 17 dBm + 10log B, where B is the 26-dB emission bandwidth in MHz. In addition, the peak power spectral density shall not exceed 17 dBm in any 1-MHz band. The EUT has a 26 dB BW of 19 MHz. Pmax = 17 + 10log(19) = 29.8 dBm Test Procedure Transmitter was placed in continuous transmit test mode. Transmitter is ON for 180 usec with a 3 usec reset OFF time. Duty cycle correction is 20 log(180/183) = -.14 dB, For reporting purposes, duty cycle correction is considered zero. Sweep time < T (transmit time) because transmitter is transmitting in continuous mode: Method 1 from Public Notice DA-02 –2138: • Set span to encompass the entire emission bandwidth (EBW) of the signal. • Set RBW = 1 MHz. • Set VBW ≥ 3 MHz. • Use sample detector mode if bin width (i.e., span/number of points in spectrum display) < 0.5 RBW. Otherwise use peak detector mode • Use a video trigger with the trigger level set to enable triggering only on full power pulses. Transmitter must operate at full control power for entire sweep of every sweep. If the device transmits continuously, with no off intervals or reduced power intervals, the trigger may be set to “free run”. • Trace average 100 t…
