Teledyne LeCroy Oscilloscopes

LeCroy offerings are grouped by measurement target and architecture rather than by a single numeric generation. Broadly:

• WaveSurfer and WaveRunner (including Xi / MXi / MXs variants) are benchtop DSOs focused on routine design and debug: compact form factors, a range of bandwidths (200 MHz up to ~2 GHz and 600 MHz variants), and practical memory depths for everyday tasks. Examples in the table include WaveSurfer 3054 (500 MHz) and WaveRunner 204MXi‑A (2 GHz).

• WavePro and WaveMaster platforms target high throughput, very high bandwidth, and long memory. These instruments use streaming or DBI interleave techniques for high sample rates and deep records; examples are WavePro 760Zi‑A and WaveMaster 816Zi.

• HDO (High‑Definition Oscilloscope) models use true 12‑bit ADCs (HD4096) for improved vertical fidelity and low‑noise measurement — see HDO4034, HDO4054, HDO4104, HDO6104, and the 8‑channel HDO8108.

• SDA and DDA are purpose‑built analyzers: the SDA 760Zi is positioned for high‑speed serial‑data and jitter analysis, and the DDA5005A is specialized for disk‑drive signal work.

When you narrow candidates, weigh these instrument attributes against your application:

• Bandwidth vs. channel count: Higher analog bandwidth instruments use techniques (interleave/DBI) that may be limited to fewer channels at the absolute top bandwidth. For example, the WaveMaster 816Zi lists 16 GHz in DBI mode on two channels and 8 GHz in standard mode on four channels.

• Sample rate and memory depth: High sample rates (examples: up to 40 GS/s on models such as WaveRunner 640Zi and WavePro 735Zi‑A) are most useful when combined with long acquisition memory. Several WavePro/WaveMaster/SDA models list optional or standard deep record lengths (for example, WavePro 735Zi‑A specifies standard and optional record‑length configurations).

• Vertical resolution and noise: HDO models provide 12‑bit ADC resolution (and software enhanced resolution up to higher effective bits), which improves small‑signal visibility compared with 8‑bit ADC instruments.

• Mixed‑signal and digital needs: The MS‑500 module supplies 36 digital channels for scopes that support L‑BUS connection, while some HDO models (for example, the HDO4104‑MS entry in the table) integrate digital channels in the chassis.

Use the following practical rules of thumb when matching a scope to typical tasks:

• Bench debug, power electronics, and routine embedded work: pick a WaveSurfer or WaveRunner model with the bandwidth and sample rate adequate for your fastest edge rates (examples: WaveSurfer 3054 at 500 MHz, WaveRunner 204MXi‑A at 2 GHz).

• Low‑noise amplitude measurements and analog fidelity: consider the HDO family (HDO4034, HDO4054, HDO4104, HDO6104, HDO8108) for their 12‑bit ADCs and enhanced resolution options.

• Very high bandwidth or serial‑data compliance and jitter work: look to WavePro/WaveMaster or the SDA/DDA analyzers (WavePro 760Zi‑A and SDA 760Zi list 6 GHz bandwidth; DDA5005A is a 5 GHz application‑specific analyzer; WaveMaster 816Zi provides 16 GHz DBI mode).

• Mixed‑signal capture: add the MS‑500 module when you need 36 digital channels of time‑aligned capture with the host oscilloscope.

Confirm the precise sample‑rate/memory/channel tradeoffs for the models you consider in the specification table below, since peak sample rates and maximum memory depth are often conditional (interleaved channels, optional upgrades, or single‑channel modes).
