The average time of occupancy on any channel shall not be greater than 0.4 seconds within a period of 0.4 seconds multiplied by the number of hopping channels employed. Frequency hopping systems may avoid or suppress transmissions on a particular hopping frequency provided that a minimum of 15 channels are used. According to RSS-2 47 § 5.1 (d ): Frequency hopping systems (FHSs) operating in the band 2400-2483.5 MHz shall use at least 15 hopping channels. The average time of occupancy on any channel shall not be greater than 0.4 seconds within a period of 0.4 seconds, multiplied by the number of hopping channels employed. Transmissions on particular hopping frequencies may be avoided or suppressed provided that at least 15 hopping channels are used. Test Procedure According to ANSI C63.10-2013, section 7.8.4 1. The EUT was worked in channel hopping. 2. Set the RBW to: 1MHz. 3. Set the VBW ≥ 3×RBW. 4. Set the span to 0Hz. 5. Detector = peak. 6. Sweep time = auto couple. 7. Trace mode = max hold. 8.
