Meas Setup
Meas Offset & Interval
This key is active only in 1xEVDO mode.
Allows you to measure the signal occupying different time domain respectively, such as the pilot in first
half slot.
Meas Offset
Specifies how long after the data capture the signal is observed.

Notes Sets the limits of the Frequency Error, which is used to judge the result of the
Frequency Error, whether it passes or fails.
If the measured Frequency Error value is not larger than the limit value, the
result is PASS. Otherwise, the result is FAIL.
