Oscilloscope lowers price of 12-bit resolution

The WaveSurfer 4000HD High Definition Oscilloscope (HDO) from Teledyne LeCroy is said to be the first in its class to feature 12-bit vertical resolution at all times, showing clean, crisp waveforms on a bright, 12.1in. touch screen display. WaveSurfer 4000HD is available in bandwidths from 200MHz to 1GHz, 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.

The WaveSurfer 4000HD answers the call as a highly affordable instrument that leverages Teledyne LeCroy’s HD4096 High Definition technology to deliver 12-bit resolution all the time.

HD4096 technology utilises a system design of high signal-to-noise input amplifiers, high sample rate 12-bit ADCs, and a low-noise system architecture to enable capture and display of waveforms with 16x more resolution than 8-bit oscilloscopes. W Its lowest baseline noise — 2.5 times better than competitive oscilloscopes with 12-bit ADCs and 8 times better than competitive oscilloscopes with 10-bit ADCs, claims Teledyne LeCroy — and highest accuracy — 0.5% versus competitors’ 2.5% at 1 mV/div gain setting.

Displayed waveforms are crisp, clean and provide visibility into signal details that are often lost in the noise on other oscilloscopes, including those with advertised 10-bit and 12-bit ADCs.

It integrates multiple instruments into one and reducing clutter on the test bench: it offers an optional 16-channel Mixed-Signal Oscilloscope (MSO), Arbitrary Waveform Generator (AWG), Frequency Counter and Spectrum Analyser (available early 2020).

The WaveSurfer 4000HD oscilloscopes are available now with prices starting at €8.735.

Standard software capabilities include a fast waveform update rate, MAUI with OneTouch, LabNotebook, History Mode and Pass/Fail testing, with several optional Protocol Analysis and Power Analysis packages available.

Comprehensive probe support spans over 30 probes in nine product categories using Teledyne LeCroy’s ProBus interface that has been unchanged for over 20 years.
