Teledyne LeCroy’s high-speed digital analyzer and probing system complete mixed-signal solution

Published: 12 February 2016 - Lisa Peake

HDA125 High-speed Digital Analyzer adds 18-channel, 12.5-GS/s digital acquisition capabilities with industry-leading sensitivity and revolutionary QuickLink probing solution to Teledyne LeCroy oscilloscopes

Teledyne LeCroy significantly expands the capabilities of its oscilloscopes with the introduction of the HDA125 High-speed Digital Analyzer. The HDA125 digital acquisition system captures 18 channels of digital data at 12.5 GS/s. Adding it to Teledyne LeCroy oscilloscopes by means of the LBUS interface architecture  results in the most flexible, highest-performance mixed-signal solution available. Also announced today is the QuickLink probing system, featuring low-cost, high-fidelity probe tips that work with both the HDA125 and Teledyne LeCroy WaveLink probes using the new Dxx30-QL QuickLink adapter.

HDA125 High-speed Digital Analyzer

The HDA125 samples 18 input signals at 80 ps intervals (12.5 GS/s) for accurate characterization of the fastest signals. However, sample rate is only half the story¾high-speed embedded systems testing often poses challenging signal amplitude conditions. The High-speed Digital Analyzer meets these challenges with a 3-GHz digital leadset, ultra-low probe loading, and industry-leading sensitivity (150 mV minimum signal swing). The system ensures the most precise digital signal interpretation with a unique hysteresis adjustment capability, and three times better threshold accuracy than competing mixed-signal instruments.

QuickLink Probing System

The QuickLink probe tip system is designed from the ground up to be compatible with both the HDA125 High-speed Digital Analyzer and with Teledyne LeCroy’s WaveLink series of differential analog probes. This cross-connection capability allows a device under test (DUT) to be equipped with QuickLink Solder-In (QL-SI) tips at all desired test points, enabling swapping of connections between digital and analog acquisition systems as needed.

Unlike other “consumable” probe tip solutions that rely on tiny, delicate tips located very close to the DUT, the QL-SI tip has an integral 9-inch lead. When connected to a WaveLink analog probe using the new Dxx30-QL adapter, QuickLink tips provide 6 GHz of bandwidth and a flat, well-controlled frequency response. Used for digital acquisitions with the HDA125, they support 3 GHz bandwidth with industry-leading sensitivity. In both cases, high input impedance (110 kO, 0.12pF differential) ensures minimal loading of the DUT.

Enhanced DDR Validation and Debug Capability

Teledyne LeCroy already offers the industry’s only dedicated DDR Debug Toolkit, designed to simplify challenging memory interface validation. Adding the HDA125 allows the DDR command bus to be directly acquired and integrated into the analysis, enabling advanced command triggering and sophisticated, searchable bus state viewing. This is complemented by the intrinsic flexibility and performance of the QuickLink probing system, which allows easy transitions between digital and analog acquisitions of the signals under test.
