Teledyne LeCroy today announced availability of the WaveSurfer 4000HD High Definition Oscilloscope (HDO), the first in its class to feature 12-bit vertical resolution at all times, showing clean, crisp waveforms on a bright, 12.1” touch screen display. WaveSurfer 4000HD is available in bandwidths from 200 MHz to 1 GHz, with sample rates of up to 5 GS/s and up to 12.5 Mpts of acquisition memory on each channel (25 Mpts interleaved). It offers versatile built-in capabilities for embedded systems debug and is compatible with Teledyne LeCroy’s comprehensive probe offerings.
Design and test engineers have come to demand the signal detail and measurement accuracy that comes with a 12-bit HDO when debugging deeply-embedded systems in IoT, automotive, switch-mode power supply and other control system designs. Other oscilloscope manufacturers make claims of 10-bit or 12-bit resolution, but their oscilloscopes lack low-noise and low-jitter components throughout their acquisition system and require tradeoffs of channel count, bandwidth or sample rate to achieve high resolution and lower noise (more info).
