Couplings If Radio Std is 802.11n or 802.11ax and Center Frequency for 5 GHz band, Clock Error limit will be
coupled to 20.0ppm
Preset If Radio Std is 802.11ac:
20.00 ppm
If Radio Std is 802.11n, 802.11ax for 2.4 GHz Band:
25.0ppm
State Saved Saved in instrument state
Min 0
Max 100 ppm
I/Q Offset (Center Freq Leakage, CFL)
Sets Center Freq Leakage limit to warn you if the measured average Center Freq
Leakage exceeds the limit.
