High Resolution / High Definition Oscilloscopes
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

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 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
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.
