The SD UHS-II bus interface technology increases secure digital performance with data rates up to 1.56 Gb/sec in consumer electronics applications. A compliance test package from Agilent Technologies Inc. helps designers accelerate the development of SD UHS-II card-based systems and ensure their interoperability.
The Agilent N6461A SD UHS-II card compliance test application, which runs on Infiniium 9000 and 90000 series oscilloscopes, provides SD UHS-II card physical-layer compliance measurements consistent with the SD Association 4.0 SD card specification.
The UHS-II memory card provides high-definition video recording with low power consumption and high data rates.
The Agilent SD UHS-II card compliance test software provides automated physical-layer testing capability for host and device transmitter tests in the SD 4.0 specification. The software automatically configures the oscilloscope for each test and generates a HTML report at the end of the test. The report compares the results with the specification test limit and indicates how closely the device passes or fails each test.
Engineers can debug data signal integrity issues using the oscilloscope SD UHS-II card compliance test application and J-BERT N4903B high-performance serial BERT. J-BERT generates test patterns like the PRBS 2^7-1 pattern that is looped back from the UHS-II memory card to the oscilloscope for signal-integrity testing.
