Modular Logic Analysis for superior mixed-signal capability

With the HDA125 High-Speed Digital Analyzer, Teledyne LeCroy has defined a totally new class of instrument – a high-performance logic analyzer module that can be combined with existing high-speed oscilloscopes to provide unparalleled mixed-signal measurement and analysis.

Modular Logic Analysis

Flexibility and performance in a single platform

Competing mixed-signal solutions require an investment in an entirely new oscilloscope. The HDA125 offers superior acquisition performance with the added benefits of mobility between existing oscilloscopes.

The HDA125 can be added to any Teledyne LeCroy oscilloscope with an LBUS or SYNC connector – from the 10-bit, 4 GHz HDO9000 family to the modular LabMaster 10Zi-A family with up to 100 GHz of analog bandwidth!

This screenshot shows a 6 Gb/s signal captured in both digital and analog domains. The HDA125 samples at 12.5 GS/s, for 80ps timing accuracy to capture the fastest signals. But in challenging signal environments, vertical performance is also critical – the HDA125 has class-leading sensitivity and ultra-low probe loading to ensure pristine digital signal fidelity.


Unmatched probing versatility

The QuickLink probe tip system was designed from the ground up to be compatible with both the HDA125 and with Teledyne LeCroy’s WaveLink series of differential analog probes. This cross-connection ability allows you to equip your system under test with QuickLink tips at all desired test points, and swap connections between digital and analog acquisition systems as needed. Industry-leading tip impedance (110 kΩ, 0.12pF differential) ensures superior signal fidelity and low loading.

When connected to a WaveLink analog probe, QuickLink tips provide 8 GHz of bandwidth and a flat, well-controlled frequency response. When used for digital acquisitions with the HDA125, they support 3 GHz bandwidth with industry-leading sensitivity. In both cases, high input impedance ensures minimal loading of the system under test.

QuickLink solder-in tips are low-cost, making it easy to equip multiple test points and DUTs, and eliminating time-consuming re-soldering of connectors. The integral 9-inch lead effectively relocates your test point to a more convenient location, and makes testing more reliable by eliminating torque and other forces on the solder joints.


Enhanced DDR debug

The HDA125 is ideally suited to the acquisition of DDR command bus signals, adding significant functionality to Teledyne LeCroy’s unique DDR Debug Toolkit.

Basic debugging and validation of embedded DDR interfaces typically involves analysis of the analog properties of the clock, data (DQ) and strobe (DQS) signals but when validation tasks become more complex and problems require deeper insight, the ability to trigger on, acquire and visualize the state of the DDR command bus is invaluable. The HDA125 brings command bus acquisition to Teledyne LeCroy’s already comprehensive toolset, providing the ultimate in memory bus analysis capability.

The HDA125 enables the unique “bus view” feature of the DDR Debug software option, which brings Teledyne LeCroy’s advanced bus analysis feature set to bear on DDR analysis. View bus activity in tabular form, and move time-correlated views to a desired event with the touch of a button. Search for specific events and bus states within the acquired record. Intuitive color overlays and annotations make it easy to identify areas of interest in the acquired analog waveforms.

The ability to trigger on specific states of the command bus becomes an invaluable tool for quick understanding of DDR signal quality. The HDA125’s logic triggering combines with the DDR Debug toolkit's intuitive setup and intelligent software cross-triggering to provide the ultimate DDR triggering system. Persistence maps of read and write bursts provide an easy and fast means of identifying subtle signal-quality problems for further investigation.


LogicStudio

The LogicStudio is a powerful solution for high-speed test and debug. For lower-speed signals, LogicStudio delivers a powerful feature set, high performance hardware and an intuitive point and click user-interface – all for under $1,000.
