Basic Rate Tests Running a Script in Standard Mode
7-22 PN: 13000-00205 Rev. N MT8852B Operation Manual
Following measurement of the 11110000 payload, packets with the alternate ones and zeros
(101010101) payload are transmitted and are looped back by the EUT.
The MT8852B calculates the average frequency of each 10101010 8-bit payload section. Then
it measures the deviation from the average frequency values for all 8-bits. These values are
called Δf2 max values.
This test is performed with hopping off, and the test is repeated until the number of packets
has been measured on each of the selected frequencies as set in the "Number of packets" field.
The table below details the test conditions and the associated default settings. Permitted
variations from the default setting are detailed in the “User Range” column.
