The Teledyne LeCroy HDA125-09-LBUS High-Speed Digital Analyzer is a modular accessory that extends oscilloscope capabilities for mixed-signal testing and digital design validation. It delivers 12.5 GS/s sampling across up to 18 digital input channels with 80 ps timing accuracy, enabling capture and analysis of high-speed interfaces such as DDR4 up to 6 Gb/s. The analyzer connects via LBUS or ChannelSync interface for precise timebase synchronization with compatible Teledyne LeCroy oscilloscopes, supporting cross-triggering between instruments. Digital waveforms display directly on the oscilloscope, time-correlated with analog traces, while bus decoding consolidates multiple digital signals into decoded displays.
