XSegmentDelta

This is a Data Header variable.

Type = Double

For OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. Error Vector Spectrum data, XSegmentDelta indicates the z-axis time difference between each spectrum vector. For OFDM Error Vector Time data, XSegmentDelta indicates the z-axis frequency difference between each time vector.
