Santa Clara, Calif.Providing options to enable accurate characterization of high-speed interfaces, Agilent Technologies Inc. introduces its J-BERT N4903A pattern generators with jitter injection capabilities. These options are for the previously introduced generators.
Useful to 7-Gbit/s and 12.5-Gbit/s, these pattern generators now let you accurately stimulate serial high-speed ports with all types of jitter. You can use them to perform characterization and compliance tests. The J-BERT N4903A pattern generators can also be used in combination with oscilloscopes, built-in error detectors, or other analyzers.
Clean And Worst-Case Signals
In use, you can inject clean, as well as worst-case jittered, pattern and clock signals into a DUT (device under test). Tools, such as oscilloscopes, built-in error ratios test, or other analyzers, can be used to monitor the behavior of the DUT under ideal and worst-case conditions.

The J-BERT N4903A pattern generators simplify worst-case jitter tolerance testing with built-in and calibrated jitter sources for random jitter (RJ), periodic jitter (PJ), and bounded uncorrelated jitter (BUJ). The system supports eye closures of greater than 0.5 UI (unit intervals).
The options extend the usefulness of these instruments in a number of ways. Agilent's Option J20, for example, emulates ISI (inter-symbol interference). You can use this to test for robustness against differential-mode or single-mode noise. You can also inject commonly used spread spectrum clocks.
The options also simplify instrument setup for serial computer bus devices. Complex training sequences can be set up with a pattern sequencer and 32-Mbytes of pattern memory. All types of clock-rate and data-rate ratios can be generated with sub-rate clock outputs.
This system can also cover all popular data rates between 150-Mbits/s and 7-Gbits/s (using Option G07) or to 12.5-Gbits/s (Option G13). You can expect accurate results based on excellent signal performance with 20-ps transition times (from 20% to 80%) and 9-ps peak-peak jitter.
Agilent's instruments also ensure grow-as-you-go functions, which lets you add J-BERT functions over time, with error detector, CDR (clock data recovery), and jitter tolerance testing.
Price And Availability
Agilent's J-BERT N4903A pattern generator options are expected to be available for ordering in March. The expected price for the 7-Gbits/s option, including the jitter sources, will be $122,000. The 12.5-Gbit/s option is expected to be priced at $138,000.
