7. 6dB Bandwidth Test
7.1.Block Diagram of Test Setup
7.2.Limit
For direct sequence systems, the minimum 6dB bandwidth shall be at least 500kHz
7.3.Test Procedure
Use the test method descried in ANSI C63.10 Section 11.8.2:
1. Set RBW = 100 kHz.
2. Set the video bandwidth (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
dB relative to the maximum level measured in the fundamental emission
