Modulation Index Test
This test measures the modulation characteristics on the EUT output for each of the selected
frequency ranges (LOW, MEDIUM and HIGH).
The MT8852B first transmits packets containing the four ones four zeros payload (11110000),
which are looped back by the EUT.
The MT8852B calculates the average frequency of each 11110000 payload section. It
measures the deviation from the average frequency for bits 2, 3, 6, and 7. These values are
called Δf1 max values.
