U4154A AXIe-Based Logic Analyzer Module

U4154A AXIe-Based Logic Analyzer Module

Agilent Technologies Inc.'s U4154A AXIe-based logic analyzer module has a capture speed of 4 Gbyte/s on 68 channels and 2.5 Gbyte/s on 136 channels with the ability to capture data on eye openings 100 ps by 100 mV. The logic analyzer module, associated probes and analysis software provide DDR (double data rate) memory systems, high-speed application-specific integrated chips, analog-to-digital converters and field-programmable gate arrays operating at speeds up to 4 Gb/s.

Timing zoom provides simultaneous state and timing measurements with 80 ps timing resolution and 256 K-sample memory depth for insight into problems by allowing simultaneous state and high-resolution timing measurements over a 20-us time span. The sequencer speed (2.5 Gb/s) gives engineers the ability to trigger reliably on sequential events on DDR memory and other high-speed signals without having to give up triggering flexibility. The eye-scan capability of the U4154A allows a quick overview of signal integrity on all signals of a DDR system in a fraction of the time it takes using alternative methods.

The U4154A logic analyzer module is compatible with Agilent's M9502A two-slot AXIe chassis. Multiple modules can be combined on a single time base and trigger sequencer. Multiple modular systems, including Agilent 16900 series frames, can be combined for time-correlated measurements on multiple buses in a system.
