Santa Clara, Calif.Test-and-measurement equipment supplier Agilent Technologies Inc. is debuting what it says is the industry's first oscilloscope-based DDR2 (double data-rate) compliance test application. DDR2 memory is an evolutionary upgrade to predecessor DDR technology. DDR2 devices feature higher bandwidths and smaller chip footprints, and dissipate less power, generating less heat.
"Adoption of DDR2 among system OEMs and system integrators is increasing, and we expect interest to continue accelerating into 2007," notes Jay Alexander, VP and general manager of Agilent's Design Validation Division. Alexander says Agilent's N5413A DDR2 test application will run on the company's existing Infiniium 54850 and 80000 Series oscilloscopes.
The N5413A DDR2 test application provides DDR2 electrical compliance measurements based on the JEDEC (Joint Electronic Device Engineering Council) JESD79-2C DDR2 SDRAM Specifications and the Intel DDR2 667/800 JEDEC Specification Addendum Rev.1.1. The JEDEC Solid State Technology Association is the semiconductor engineering standardization body of the EIA (Electronic Industries Alliance) trade association.
The N5413A test app also features Advanced Debug mode. It provides crucial measurements such as eye-diagrams, mask tests, ringing measurements, and other tests not covered in the JEDEC specs. This mode can help you discover the root causes of problems in designs.
With the N5413A DDR2 compliance test application, you can use an ordinary oscilloscope to perform automated testing and margin analysis. The application automatically configures scope for each test and provides informative reports. It also includes margin analysis that indicates how closely a device passes or fails each test.
When conducting DDR2 tests, you may encounter difficulties connecting to the target device, configuring the oscilloscope, performing the tests and analyzing the measured results. The DDR2 compliance test application therefore guides you through these steps and does most of this work for you.
If a designer discovers a problem, the Advanced Debug features in the test application, and debug tools in the oscilloscope, are available to aid in root-cause analysis. The Advanced Debug function also includes a unique technique that separates Read/Write burst signals on the same bus. That gives you a powerful tool for debugging.
Accurate And R
So, why is this significant? Well, with increasing data rates and decreasing window validity times of DDR2 memories, signal integrity of measurement tools is critical to achieving accurate and repeatable measurements.

Using an Agilent Infiniium 80000 Series oscilloscope and InfiniiMax probing ensures low noise-floor, low jitter measurement floor, low trigger jitter, and flat frequency response. That can help optimize DDR2 design margins.
Price And Availability
The price for the N5413A DDR2 compliance test application is $3,001. Current Agilent N5413A DDR2 clock characterization application owners can upgrade to the DDR2 compliance test application at no cost.
