eMMC compliance test application High-power, battery-operated portable Agilent Technologies announced what the company claims PIM test analyser to be the industry’s first eMMC (embedded multimedia card) The PIM Master MW82119A passive intermodulation (PIM) test compliance test application for embedded storage solutions. analyser from anritsu is battery-operated, portable and one The Agilent N6465A eMMC test appli- quarter the size and half the weight of alternative PIM test solu- cation helps memory design engineers tions according to the manufacturer. validate and debug eMMC NAND flash The MW82119A offers the inherent memory cards faster by automating advantages of PIM Master, including the execution of a series of parametric 40W testing and Anritsu’s patented tests, including electrical and timing Distance-to-PIM (DTP) in a compact measurements, on Agilent Infiniium housing suited for difficult-to-access 9000, 90000A, 90000 X- and 90000 Q-Series oscilloscopes. sites, such as remote radio Head The eMMC NAND flash memory technology can operate (RRH) installations and indoor Distributed Antenna Systems at a maximum clock rate of 200 MHz in high-speed mode (DAS). Six models are available to address major frequency and provides ultrafast memory for smartphones, tablets and ranges, including the upper and lower 700MHz bands, 850MHz, other mobile devices. The eMMC standard is widely used. 900MHz, 1800MHz, 1900MHz, and 1900/2100MHz.

Testing is simplified by the www.agilent.com analyzer’s ability to save and recall test set ups for standardized testing, and limit lines can be set for visual and/or audible pass/ fail criteria. Anritsu’s Line Sweep Tools can be used to manage MIMO wireless channel emulation PIM Master MW82119A measurements, and generate reports that combine VSWR data as well as PIM data into a unified site logic subsystem report.

When applied to a wireless signal using digital signal www.anritsu.com processing, channel emulation makes the signal appear as though it has traversed Small-footprint milling machine improves a realistic indoor or outdoor space, having been reflected from walls, cars, package decapsulation workflows people or other surfaces. With octoFade, Ultra Tec Manufacturing’s Blue Mill Pre-Cavitation and channel emulation can be integrated into Gasket Milling System addresses several key challenges that wireless test equipment such as vector signal generators (VSG) limit the usefulness of chemical decapsulation (acid) sys- and base-station emulators. octoFade implements channel tems by quickly and effectively models defined by standards bodies such as IEEE 802.11 and pre-cavitating ‘difficult’ mold 3GPP. These channel models emulate the effects of multipath compounds and other electronic and Doppler fading occurring in typical indoor and outdoor packaging materials for electron- environments. octoFade is the first computational subsystem ic failure analysis and counterfeit of a MIMO wireless channel emulator being offered stand-alone prevention.
