Teledyne LeCroy Oscilloscopes

LeCroy groups its oscilloscopes into several use‑oriented families. WaveSurfer models are compact benchtop instruments for everyday debugging (examples: WaveSurfer 3054 at 500 MHz and WaveSurfer 104MXs-A at 1 GHz). WaveRunner and WaveRunner Xi/MXi variants sit between general‑purpose and high‑performance instruments (examples: WaveRunner 104MXi at 1 GHz and WaveRunner 640Zi at 4 GHz). WavePro and the WavePro Zi‑A series target high bandwidth, long‑memory, and high sample‑rate lab applications (examples: WAVEPRO 7200 at 2 GHz and WavePro 735Zi-A at 3.5 GHz). For ultra‑high bandwidth and specialist analysis, LeCroy offers instruments such as WaveMaster 816Zi (16 GHz DBI mode on two channels) and application‑specific platforms like DDA5005A (5 GHz disk‑drive analysis) and SDA 760Zi (6 GHz serial data analyzer). The HDO family is set apart by a high‑definition ADC architecture (12‑bit) for low‑noise, high‑resolution waveform capture.

Bandwidth and sampling capability are primary selection criteria. Examples: WaveRunner 640Zi and several WavePro Zi models list interleaved/sample modes that reach 40 GS/s on one or two channels and 20 GS/s in some multi‑channel configurations; SDA 760Zi specifies 40 GS/s on two channels and 20 GS/s on four channels. Memory depth affects long records and post‑processing: WavePro 735Zi-A documents standard and optional memory up to 256 Mpts/Ch, while HDO6104 lists a standard 50 Mpts/Ch. Vertical resolution is a key differentiator for small‑signal fidelity — HDO4034 and HDO6104 use a true 12‑bit ADC with enhanced resolution options. Form factor and portability vary: WaveJet 354A is a 500 MHz portable DSO, while larger displays and throughput targets appear on the WavePro Zi and WaveMaster platforms.

Bench troubleshooting and embedded work: choose a WaveSurfer model that matches the required bandwidth and sample rate (for example, WaveSurfer 3054 at 500 MHz or WaveSurfer 104MXs-A at 1 GHz) to get a compact instrument with touchscreen operation. Mixed‑signal and logic capture: add the MS‑500 module for 36 digital channels when the host oscilloscope supports it. High‑speed serial and compliance testing: consider WavePro Zi or SDA platforms — SDA 760Zi and WavePro Zi instruments document multi‑GHz bandwidth with 20–40 GS/s sampling modes. Precision, low‑noise analog measurements: HDO series instruments (HDO4034, HDO6104) provide 12‑bit hardware resolution and enhanced‑resolution modes for improved vertical detail. Specialist needs: DDA5005A is configured for disk‑drive analysis; WaveMaster 816Zi targets the very highest analog bandwidths.

LeCroy supports probe interfaces and MSO expansion. The MS‑500 module adds 36 digital channels and supplies user‑defined thresholds and timing correlation to the host’s analog channels. Many models reference ProBus/ProLink or ProBus probe interfaces for channel multiplexing and probe support. When reviewing the model table, confirm the probe interface, input coupling and maximum input voltages for the probes and probes’ required probe types against the signals under test.
