A compact USB 2.0 compliance test solution, based on the company's
DL9240/9240L family of high-performance digital oscilloscopes, has been
announced by Yokogawa in the form of the busXplorer-USB.
Consisting of a USB compliance test fixture and test software, the new
product takes advantage of the oscilloscopes' wide variety of trigger and
analysis functions to offer a system for carrying out highly automated USB
compliance tests. It is designed for use with a probe such as the wide
bandwidth PDB2000 differential probe, wide bandwidth PBA2500 active probe,
or 701933 current probe.
In addition to facilitating execution of the various tests from a PC via an
Ethernet connection, the test software displays detailed test procedures
including the wiring method, allowing it to be used by inexperienced
operators.
The busXplorer-USB is ideally suited to compliance testing in the
development phase by allowing execution of specific tests and repeated test
execution. It also features a variety of convenient functions for carrying
out tests on the USB physical layer and on interfaces and connected devices,
making it very useful as a USB interface hardware development support tool
during the engineering stages, says the company.
If initial test results indicate problems, detailed analyses of signal
waveforms and management of test results can be performed by using the
system in conjunction with the company's Xviewer waveform analysis tool.
The DL9240/9240L are the highest-performance models in Yokogawa's
SignalXplorer DL9000 Series of digital oscilloscopes, and feature an
enhanced waveform accumulation function that allows up to 450 million
digitised points to be acquired and displayed every second.
The 4-channel instruments measure only 350mm x 200mm x 178mm and weighs only
6.5 kg. Bandwidth is 1.5GHz and maximum sampling rate is 10GS/s. The DL9240
has 2.5M of memory on each channel and the DL9240L has 6.25M on each
channel.
