Test Setup EUT Attenuator Spectrum Analyzer 3.2. Limit 3.2.1. FCC According to §15.247(a)(2), systems using digital modulation techniques may operate in the 902-928 ㎒, 2 400-2 483.5 ㎒, and 5 725-5 850 ㎒ bands. The minimum 6 ㏈ bandwidth shall be at least 500 ㎑. 3.2.2. IC According to RSS-247 Issue 2, 5.2(a), the minimum 6 ㏈ bandwidth shall be 500 ㎑. 3.3. Test Procedure 3.3.1. 6 ㏈ Bandwidth The test follows section 11.8 DTS bandwidth of ANSI C63.10-2013. Tests performed using section 11.8.1 Option 1. - Option 1: 1. Set RBW to = 100 ㎑. 2. Set the VBW ≥ 3 x RBW. 3. Detector = peak. 4. Trace mode = max hold. 5. Sweep = auto couple. 6. Allow the trace to stabilize. 7. Measure the maximum width of the emission that is constrained by the frequencies associated with the two outermost amplitude points (upper and lower frequencies) that are attenuated by 6 ㏈ relative to the maximum level measured in the fundamental emission.

However, a peak, or peak hold, may be used in place of the sampling detector since this usually produces a wider bandwidth than the actual bandwidth (worst-case measurement). Use of a peak hold (or “Max Hold”) may be necessary to determine the occupied / x ㏈ bandwidth if the device is not transmitting continuously. ● The resolution bandwidth (RBW) shall be in the range of 1 % to 5 % of the actual occupied / x ㏈ bandwidth and the video bandwidth (VBW) shall not be smaller than three times the RBW value. Video averaging is not permitted. Note: It may be necessary to repeat the measurement a few times until the RBW and VBW are in compliance with the above requirement. For the 99 % emission bandwidth, the trace data points are recovered and directly summed in linear power level terms. The recovered amplitude data points, beginning at the lowest frequency, are placed in a running sum until 0.5 % of the total is reached, and that frequency recorded. The process is repeated for the highest frequency data points (starting at the highest frequency, at the right side of the span, and going down in frequency). This frequency is then recorded. The difference between the two recorded frequencies is the occupied bandwidth (or the 99 % emission bandwidth).
