Emerging Innovations • • Industry’s ﬁrst MIPI D-PHY test solution facilitates debugging DNA replication ﬁndings may explain disease origins EMERGING INNOVATIONS Agilent’s new mobile industry processor interface (MIPI) D-PHY protocol test solution features the Agilent N4851A analysis probe and N4861A stimulus probe. This ﬁrst-to-market system, based on the Agilent 16900 logic analyzer platform, supports camera serial interface (CSI-2) and display serial interface (DSI) and facilitates hardware and software debugging, reducing the need for interoperability testing. Real-time analysis and stimulus hardware provide bit-level-to-image-level test capabilities, hierarchical protocol display, real-time error detection, and automated tools for test-vector generation, allowing users to simulate, troubleshoot and verify designs. Researchers at the Baylor College of Medicine have observed a new way that DNA additions or deletions are introduced in genes during cell division. The replications have been associated with a wide range of diseases such as Alzheimer’s, Parkinson’s, Potocki-Lupski Syndrome, and others. The ﬁndings — aided by Agilent’s custom oligonucleotide comparative genomic hybridization microarrays — were published in the journal Cell with details about how this newly discovered method, called replication fork stalling and template switching (FoSTes), adds or deletes segments of DNA in previously unexpected locations during replication. Baylor researchers studying Pelizaeus-Merzbacher disease (PMD) with the new FoSTes method found genomic changes, such as extra genetic material in the middle of another duplication, that previous DNA theories could not explain. • Oscilloscope ﬁrmware upgrade runs MATLAB® scripts Researchers and designers can now run MATLAB scripts and directly calculate transmitter waveform dispersion penalty (TWDP) and other performance parameters without external processing courtesy of a ﬁrmware update for the Agilent 86100C Inﬁniium DCA-J wideband oscilloscope. A compliance methodology adopted by IEEE 802.3aq 10G Ethernet (LRM), TWDP quantiﬁes transmitter performance for systems using dispersive channels and equalizing receivers. The updated ﬁrmware (revision 8.0) sends live oscilloscope waveforms to MATLAB where they can be analyzed directly. In addition, engineers can use any MATLAB script from any standard, or they can write their own scripts for custom outputs. The results are faster development cycles and greater insights toward design improvements. • Scripting features highlight new AMDS offering The latest release in Agilent’s Antenna Modeling Design System (AMDS) is now available. The new full-wave, 3-D electromagnetic modeling and simulation software contains a scripting feature that automates complex designs such as patch-array antennas. The enhancements enable designers to ﬁne tune antennas for better performance within electronic devices such as cell phones. They also streamline and introduce greater accuracy into post-processing computations by allowing designers to write their own programs to automate element placement and incorporate mathematical functions that can perform antenna design analysis. 4 Agilent Measurement Journal
