7.7 Peak Power spectrum density
Test Requirement 47 CFR Part 15, Subpart C 15.407 (a)
Test Method: KDB 789033 D02 II F
Limit:
Frequency band(MHz) Limit
5150-5250
≤17dBm in 1MHz for master device
≤11dBm in 1MHz for client device
5250-5350 ≤11dBm in 1MHz for client device
5470-5725 ≤11dBm in 1MHz for client device
5725-5850 ≤30dBm in 500 kHz
Remark:
The maximum power spectral density is measured as a conducted emission
by direct connection of a calibrated test instrument to the equipment under
test.

Description
Final test 05
TX mode (U-NII-1)_Keep the EUT in continuously transmitting mode with all
modulation types. All data rates for each modulation type have been tested and
found the data rate @ 6Mbps is the worst case of IEEE 802.11a; data rate @ MCS0
is the worst case of IEEE 802.11n(HT20); data rate @ MCS0 is the worst case of
IEEE 802.11n(HT40); data rate @ MCS0 is the worst case of IEEE
802.11ac(VHT20); data rate @ MCS0 is the worst case of IEEE 802.11ac(VHT40);
data rate @ MCS0 is the worst case of IEEE 802.11ac(VHT80); data rate @ MCS0 is
the worst case of IEEE 802.11ax(HE20); data rate @ MCS0 is the worst case of
IEEE 802.11ax(HE40); data rate @ MCS0 is the worst case of IEEE
802.11ax(HE80);data rate @ MCS0 is the worst case of IEEE 802.11ax(HE160).
Only the data of worst case is recorded in the report.
