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.
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:
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.
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.
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.
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.
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:
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.
This white paper provides an overview of the various high resolution oscilloscope design approaches, with examples of their impact on oscilloscope performance and data on Teledyne LeCroy, Keysight, Rohde & Schwarz and Tektronix oscilloscope high resolution performance.
Oscilloscope manufacturers use a variety of design approaches to increase resolution, some of which impose other performance tradeoffs. Join Ken Johnson for this two-part webinar series to gain a better understanding of various manufacturer’s claims.
This webinar will provide attendees with an overview of digital power management, power-rail measurements, and power-rail sequencing, as well as accurate and reliable measurement solutions for PMIC-based control systems, including analysis of such systems under transient load conditions.
