Parametric x ray radiation in crystals theory experiments and applications

This systematic and entire monograph is dedicated to parametric X-ray radiation (PXR). This radiation is generated by means of the movement of electrons inside of a crystal, wherein the emitted photons are diffracted via the crystal and the radiation depth significantly depends on the parameters of the crystal constitution.

Example text

The recovered PRBS seed result is presented on the Sym/Errs table. The user can decompose this 11-bit Status value into a Frame Number and IDCell for the UL in order to confirm that the settings match expectations. ”) is presented if the 89600 software cannot uniquely identify the PRBS seed. This may indicate an incorrect PRBS generator, or insufficient data to deduce the PRBS. Since the PRBS determines the carrier and pilot positions, a correct PRBS is vital to even beginning measurements. This unique 89600 VSA software capability can help you troubleshoot your early development efforts and get a working design as quickly as possible.

The resulting zone definition grid is shown in Figure 26, and the corresponding measurement results are shown in Figure 27. Figure 26. This zone definition grid has been modified to explore the effects of incorrect data burst length and demodulation type (16QAM instead of 64QAM). The demodulation results are shown in Figure 27. Figure 27. Incorrectly defining the zone map for data burst analysis causes large errors where 64QAM (from an adjacent burst) is demodulated as 16QAM, and symbols for inactive carriers are shown at the center of the constellation diagram.

Incorrectly defining the zone map for data burst analysis causes large errors where 64QAM (from an adjacent burst) is demodulated as 16QAM, and symbols for inactive carriers are shown at the center of the constellation diagram. 53 Advanced Digital Demodulation (continued) Several results in all of the analyzer displays are useful for troubleshooting the kind of problems introduced in this example. The constellation display now includes a number of 64QAM symbols without targets in addition to the expected 16QAM symbols and targets.
