Provide comprehensive testing capabilitieYokogawa has introduced two compact, easy-to-use and economical instruments for 10Gbps bit-error-rate testing. The AQ2200-601 is based on the AQ2200 modular platform and is suited to both laboratory and manufacturing applications, while the AP9945 is a portable unit which is ideal for field testing.

According to the company, these two instruments provide comprehensive testing capabilities for 10Gbps networks as well as Ethernet and 10Gbps components such as transmitter and receiver optical subassemblies, XFP transceivers and PIN diodes. Both offer pulse pattern generation from 9.95Gbps up to 11.32Gbps, as well as variable amplitude, offset and crosspoint settings. Internal clock data recovery makes it very easy to run tests without providing a separate clock signal.

The AP9945 is designed to be controlled by an external PC. All functions and features can be set through the software delivered with the instrument. PRBS (pseudo-random binary sequence) patterns can be selected between PRBS 7 and PRBS 31.

The AQ2200-601 offers a 64Mb program pattern option which allows users to create their own custom patterns including SDH or SONET patterns. These patterns, defined using the PC-based software, can be stored on a flash card and transferred to the pulse pattern generator.
