So many product designs these days include high-speed USB connectivity. If you're designing-in USB 2.0, check out the busXplorer USB 2.0 compliance test solution from Yokogawa Corp. of America. It comprises a compliance test that ensures your designs will meet all USB specs defined by the USB Implementers Forum (USB-IF).

The new solution consists of a USB test fixture and USB compliance test software. These work together with Yokogawa's existing DL9200 digital oscilloscope, which is controlled by your PC across an Ethernet connection.

A scope, the test fixture, and a notebook will put you in full control of USB 2.0 test. The DL9200 digital scope that Yokogawa recommends is a 1.5GHz instrument.

The DL9200 offers up to 6.25Mpoints of memory per channel on four channels. In addition, a the scope performs sampling at speeds up to 10GSps. It also includes a plethora of advanced triggering and detailed waveform search capabilities.

When combined with current probes and high-bandwidth active and differential probes, the scope gives you waveform analysis capabilities that are just the ticket for USB 2.0 testing as well as general-purpose lab use.

Additionally, the DL9200 offers triggering on and analysis of lower speed serial data buses including I2C, SPI, CAN, HDMI and others, as well as UART analysis.

The busXplorer USB 2.0 compliance test solution performs all USB high-speed device, host and hub electrical tests, as well as legacy (low-speed and full-speed) tests, as defined by the USB-IF.

Yokogawa's USB test fixture consists of USB connectors for attaching the device, host or hub being tested. The fixture also includes test points for various active, differential and current probes.

The user-friendly USB compliance test software provides explicit step-by-step instructions on how to proceed. The software also includes diagrams of device-to-test fixture connections, so that you can complete the compliance tests in a straightforward manner.

The software lets you perform detailed waveform troubleshooting and analysis by linking to Yokogawa's Xviewer Waveform Analysis software (a separate product). The USB compliance test software organizes test results by creating and automatically naming a report for every test of each device.
