USB Battery Charging Test Tool For Mobile Phones, Devices

(November 17th, 2009)
Recently, Allion announced a
USB Battery Charging Test Fixture pre-sale, which runs through the end of this month. This USB testing tool easily measures the performance of mobile phone device chargers. The test fixture looks at power consumption, over shoot (signal or function exceeding steady-state value), under shoot (signal or function lower than steady-state value) and short-recover time. The USB test fixture was developed to adhere to the Battery Charging 1.1 Specification defined by the USB Implementers Forum (USB-IF).USB Battery Charging 1.1One feature that makes USB a compelling interconnect technology is its battery charging ability. As USB devices become more powerful and advance with new features, new battery charging capabilities are needed. This is where the USB Battery Charging 1.1 specification, which was released as a new USB Device Class specification earlier this year, comes into play.
New capabilities enabled by Battery Charging 1.1:
Device detection whether they are attached to a PC or charging port. When attached to a charging port, devices can draw power before they are recognized.
Portable devices with dead batteries are now able to draw current from a PC before they are recognized.
Devices plugged into a docking station can act as host to downstream peripherals, while drawing current from the docking station.
The Accessory Charger Adapter enables a portable device with a single Micro-USB connector to charge at the same time it is attached to another device, such as a headset.
Portable devices can reduce connector costs by offering battery charging, connection to a host and/or connection to a peripheral using a single Micro-USB receptacle.
USB test equipment can effectively enhance testing during all product development stages. Allion strives to deliver the most cost effective and competitive testing fixtures to fulfill the needs of developers. Quality testing ultimately leads to quality products and financial savings for customers.

SATA Revision 3.0


(November 11th, 2009)

In May 2009, Serial ATA International Organization (
SATA-IO) released the SATA Revision 3.0 specification, which builds upon the success of previous generations of SATA storage device interface technology. Here’s a quick snapshot of the benefits and applications for this new spec:
SATA 3.0 Benefits
Link speeds of 6 Gb/s – twice as fast as SATA Revision 2.0
Low cost
Low power consumption
Backward compatible with previous SATA generations
SATA Interface Usage Found In:
Storage units
Disk drives
Optical
Tape drives
Host bus adaptors
Currently, products based on SATA Revision 3.0 are being introduced to the market for consumers to purchase. Recently, ASUS released the P7P55D-E Premium and P6X58D Premium motherboards. These motherboards contain both SATA 6G (a reference to the 6Gb/s signaling rate) and
SuperSpeed USB (USB 3.0) technology, providing consumers with the connections available both inside and outside of the box. As more SATA 6G technology reaches consumers, it will pave the way for faster internal and external storage, significantly enhancing the computing experience.
Products that have successfully completed rigorous
testing for SATA specification interoperability and compliance, assuring products work with other SATA certified devices, are added to the SATA Integrators List . An easy way to participate in SATA interoperability testing is to work with an independent test lab.
Authorized by SATA-IO since 2004, Allion is one of the first official
SATA independent test labs offering third party validation for products seeking SATA certification. Each SATA certified logo indicates adherence to the respective SATA specification and can be used on product packaging, Web sites and collateral when the product passes SATA interoperability testing.
Several products incorporating SATA Revision 3.0, including the Marvell® 88SE9128 controller (utilized in the ASUS motherboards), Seagate Barracuda® XT hard drive and Toshiba’s line of 7,200 RPM 2.5-inch Hard Disk Drives, are currently available in the market. Additional certified products will be available in the first half of 2010.

Windows 7 Testing and Ecosystem Interoperability


This week marked the availability of Windows 7 to consumers worldwide. The operating system is being touted as a vast improvement over its predecessor, Windows Vista. One item that Microsoft focused intensely on when developing Windows 7 was user experience – providing a smooth, snappy and bug free experience for its customers.
So what steps are necessary to deliver a positive experience across the millions of possible PC configurations in the marketplace?
Earlier this summer, we detailed the
Windows Logo Program. This program, primarily for hardware manufacturers, ensures that systems and devices will function properly with Windows operating systems (Windows Server® 2008 R2, Windows Server 2008, Windows Vista and Windows 7). It also signals to consumers that the product has been tested to verify it meets Microsoft standards for Windows compatibility. This is essential as consumers worldwide load their new Windows 7 discs into millions of PCs from hundreds of manufacturers. What could be a compatibility nightmare appears to be a smooth transition that is bolstering Microsoft’s position in the market. To further ensure that consumers do not run into any roadblocks while making the transition to Windows 7, Microsoft has enhanced the requirements to receive a logo for Windows 7 hardware.

A new requirement mandates that firms seeking a Windows Logo first secure a USB certification. USB certification is a critical certification in the PC industry, and it will minimize the chance of a consumer’s USB device not performing as anticipated with the Windows operating system. The new policy is critical for hardware vendors and system manufacturers, who are preparing to submit their USB devices and systems for Windows Logo Program submission.
Simply stated, any devices (webcams, keyboards, mice) or hosts (desktops, laptops or netbooks) seeking a Windows logo must first receive certification from the
USB Implementers Forum. This certification guarantees compliance to the USB standard and in turn, promotes the greatest level of interoperability between USB hosts and devices.
For consumers, this new requirement is an important step. It will ensure that purchased devices carrying the Windows and certified USB logos will work as expected with their PC bearing the logos.
