Bit-error-rate tester takes DesignVision Award
Agilent Technologies has won a 2007 DesignVision Award in the test and measurement category for its J-BERT N4903A.
The Agilent J-BERT N4903A pattern generators can be used in combination with oscilloscopes, built-in error detectors or other analysers.
The next generation of multigigabit devices using technologies such as PCI Express, Serial Advanced Technology Attachment and fully buffered DIMM (dual inline memory module) are being introduced in the computer industry.
Engineers need simple, cost-efficient test solutions for characterisation and conformance testing of these high-speed interfaces to meet time to market and cost objectives.

More modules for multifunction measurement unit
Two new modules join the 19 modules already offered to make up a high-performance family of eight-slot mainframe switches with built-in DMMs.
The new Agilent J-BERT N4903A 7 and 12.5Gbit/s pattern generator options are cost-efficient digital stimuli, enabling quick and accurate characterisation and compliance test of high-speed serial interfaces.
Design and test engineers can use the J-BERT pattern generators to inject clean as well as worst-case jittered pattern and clock signals into the device under test.
Analysis tools, such as oscilloscopes, built-in error ratios test (BIST), or other analysers can be used to monitor the behaviour of the device under test under ideal and worst-case conditions.
The J-BERT N4903A pattern generators enable fast and accurate testing by: simplifying worst-case jitter tolerance testing with built-in and calibrated jitter sources for random jitter (RJ), periodic jitter (PJ) and bounded uncorrelated jitter (BUJ); emulating inter-symbol interference (ISI) (option J20); testing robustness against differential-mode or single-mode noise (option J20); injecting commonly used spread spectrum clocks (SSC); simplifying instrument setup for serial computer bus devices; covering all popular datarates between 150Mbit/s and 7Gbit/s (option G07) or to 12.5Gbit/s (option G13); giving accurate results based on excellent signal performance with 20ps transition times (20-80%) and 9ps peak-peak jitter; and providing grow-as-you-go functionality, which allows the user to add complete J-BERT functionality over time with error detector, CDR and complete jitter tolerance test.
"The new Agilent J-BERT 7 and 12.5Gbit/s pattern generators offer significant time and cost savings for design and test teams", said Siegfried Gross, Agilent's Digital Verification Solutions General Manager.
"Once again, Agilent demonstrates its leading role in physical layer testing".
The new Agilent J-BERT N4903A pattern generator options are expected to be available for ordering in March 2007.
The expected price for the 7Gbit/s option including the jitter sources for RJ, PJ and BUJ is US $122,000, and $138,000 for the 12.5Gbit/s option.
