Teledyne LeCroy WaveSurfer 4104HD 1 GHz, 12-bit High Definition Oscilloscope

The Teledyne LeCroy WaveSurfer 4104HD is a 1 GHz, 12-bit high-definition digital oscilloscope built for signal analysis and troubleshooting across power electronics, automotive, and embedded design applications. The instrument delivers 12-bit vertical resolution via HD4096 technology - providing 4096 discrete levels and 16× greater resolution than conventional 8-bit oscilloscopes. This enables cleaner waveforms and superior signal fidelity for low-level measurements.

Four analog channels pair with optional 16 digital channels for mixed-signal capture. The 12.1-inch capacitive touch screen and MAUI with OneTouch interface streamline setup and operation.
