The digital acquisition system interfaces to the company’s oscilloscopes by means of the LBUS interface architecture to give what is claimed as the most flexible, highest-performance mixed-signal solution available. Also inroduced 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 Dxx30-QL QuickLink adapter.

The HDA125 samples 18 input signals at 80 psec intervals (12.5 Gsample/sec) for accurate characterisation of the fastest signals. High-speed embedded systems testing often poses challenging signal amplitude conditions, which the analyser addresses with a 3-GHz digital leadset, ultra-low probe loading, and sensitivity of 150 mV minimum signal swing. The system ensures precise digital signal interpretation with an hysteresis adjustment capability; LeCroy says it has three times better threshold accuracy than competing mixed-signal instruments.

The QuickLink probe tip system is a new design, compatible with both the HDA125 High-speed Digital Analyser and with Teledyne LeCroy’s WaveLink series of differential analogue 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 analogue 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 analogue probe using the 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 highest sensitivity. In both cases, high input impedance of 110 kΩ + 0.12 pF differential ensures minimal loading of the DUT.


Teledyne LeCroy already has a 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 analogue acquisitions of the signals under test.
