The HDA125 High-speed Digital Analyser launched by Teledyne LeCroy expands the capabilities of its oscilloscope range. The HDA125 digital acquisition system captures 18 channels of digital data at 12.5GS/s. It can be added to Teledyne LeCroy oscilloscopes by means of the LBUS interface architecture.
Also announced 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.
The HDA125 samples 18 input signals at 80 ps intervals (12.5 GS/s) for accurate characterisation 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 Analyser meets these challenges with a 3GHz digital leadset, ultra-low probe loading, and industry-leading sensitivity (150mV 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.
The QuickLink probe tip system is designed from the ground up to be 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 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 analogue probe using the new Dxx30-QL adapter, QuickLink tips provide 6GHz of bandwidth and a flat, well-controlled frequency response.
Used for digital acquisitions with the HDA125, they support 3GHz bandwidth with industry-leading sensitivity. In both cases, high input impedance (110kΩ, 0.12pF differential) ensures minimal loading of the DUT.
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.
