Time Offset (NB-IoT)

Time Offset shows the time offset from the beginning of the time capture to the beginning of the Measurement Interval.

For example, when Time Offset = 5 ms and the Search Time trace starts at -8.3 ms, the beginning of the Measurement Interval is located at -3.3 ms within the Search Time trace.

Time Offset can be used to measure the accuracy of an external frame trigger signal when

a frame trigger signal is connected to the external trigger
Analysis Start Boundary is set to Frame
and Measurement Offset is set to 0

In this case, Time Offset will show the offset between the frame trigger and the actual start of the frame.
