The Best High Resolution Oscilloscopes are 12 Bits All The Time

Teledyne LeCroy High Definition Oscilloscopes (HDO®) provide 12 bits of resolution all the time from 200 MHz up to 65 GHz. Once you use a Teledyne LeCroy HDO, you’ll never want to go back to using another oscilloscope.

  • No tradeoff of resolution, sample rate, or bandwidth
  • Clean, crisp waveforms
  • More signal details
  • Unmatched measurement precision

Compare Teledyne LeCroy High Definition Oscilloscopes (HDO)

High resolution oscilloscopes provide more resolution compared to a conventional 8-bit oscilloscope. A High Definition Oscilloscope (HDO) is Teledyne LeCroy’s class of oscilloscopes that provide 12-bit oscilloscope resolution all the time with no reduction of bandwidth or sample rate. Teledyne LeCroy HDOs are available from 200 MHz to 65 GHz, with 4 to 8 channels (or more, using OscilloSYNC®). Compare Teledyne LeCroy HDOs below:

Comparison of Teledyne LeCroy high resolution oscilloscope with competitive oscilloscopes that reduce performance to obtain high resolution

12-Bit Resolution All The Time, By Design

Teledyne LeCroy High Definition Oscilloscopes provide high resolution and low noise all the time. Other manufacturers use software post-processing with reduced bandwidth at higher resolution. Only Teledyne LeCroy provides 12 bits all the time.

12 Bits for Lower Noise, Higher Measurement Precision

12-bit oscilloscope resolution capturing wide dynamic range and wide bandwidth signal with lower noise and higher precision

Teledyne LeCroy 12-bit Resolution HDO Provides Superior Results

Low noise and high resolution at full bandwidth is required to measure signals with wide dynamic range and wide bandwidth, such as the signal with zoom shown to the left.

  • A – Clean, crisp waveforms are captured on Teledyne LeCroy HDOs
  • B – More signal details are clearly visible and easy to distinguish
  • C – Unmatched measurement precision for improved debug and analysis
8-bit oscilloscope resolution capturing wide dynamic range and wide bandwidth signal – has more noise and worse measurement precision

8-bit Oscilloscope Resolution Provides Worse Results

An 8-bit resolution oscilloscope does a much worse job of capturing and displaying signals with high accuracy and precision compared to a Teledyne LeCroy 12-bit resolution HDO. 8-bit quantization levels are clearly visible in the zoomed area.

  • A – The unzoomed signal may look similar to the 12-bit capture, but thicker
  • B – Wide dynamic range signals won’t display signal details when zoomed
  • C – Quantization levels interfere with measurement precision at very low amplitudes

16x More Resolution Compared to 8-bit Oscilloscopes

Teledyne LeCroy 12-bit High Definition Oscilloscopes have 4096 discrete vertical levels to reduce the quantization error compared to the 256 vertical levels of an 8-bit oscilloscope.

  • Improves accuracy and measurement precision of the signal capture
  • Increases measurement confidence

Teledyne LeCroy HD4096® Technology for Superior Results

Teledyne LeCroy’s HD4096 uses a systems design approach to achieve high resolution and the lowest possible noise at full oscilloscope bandwidth. The three pillars of HD4096 technology are:

  • High sample rate 12-bit ADCs
  • High signal-to-noise input amplifiers
  • Low noise system architecture

What is the Difference Between a High Resolution Oscilloscope and a High Definition Oscilloscope?

Some oscilloscopes use a high-resolution setting or high-resolution acquisition mode to improve resolution from 8 bits to 12 bits. Some oscilloscope manufacturers even claim 16 bits. What can you believe? Download the white paper or watch the two-part webinar to learn more.
