An improved gated-oscillator time-base and associated auto-calibration algorithm for use in a high-accuracy sampling waveform acquisition system are described. The time-base architecture consists of a stable 100 MHz gated-oscillator, 24-bit counter chain, and a clock period interpolator. The nominal, uncorrected linearity of the time-base is approximately /spl forall/30 ps. By using an iterative, sine-fit based algorithm, the linearity has been improved to </spl forall/5 ps.

Correction of time base error for high speed sampling oscilloscope
TLDR
Reason of time base error causes and the influence for measurement and calibration, the method for correction or compensation were studied and results had good results as the experiment data were processed.

Abstract: An accurate sampling system for calibrating the pulse response of real-time digitizing oscilloscopes up to 100 V is described. The measurement system is the result of ongoing efforts at the
The design of a wide bandwidth time marker generator.
TLDR
This paper proposes a design that will generate the time marker whose samples are synthesized by real-time calculation instead of storing them in a LUT, and builds a 4-WDSPS TMG based on this design and reduced the required clock frequency from 1 GHz to 250 MHz, thus making the implementation possible in an FPGA.
Nonrandom quantization errors in timebases
TLDR
A novel timebase compensation method is proposed which makes the measured RMS errors normally distributed and reduces their standard deviation by a factor of 25 and this compensation method was applied to a sampling voltmeter and the improved accuracy was realized.

TLDR
The circuit design approach is applicable to comparators intended for use in equivalent-time, successive approximation analog-to-digital conversion where required bandwidths may exceed 1 GHz and digitizing resolution may be as high as 16 bits.
Estimation of Within Cycle Dynamics of an SI Gasoline Engine Using Equivalent Cycle Reconstruction
TLDR
Results of estimation based on engine data using an industry standard simulator confirm that it is possible to faithfully track states evolving under the within cycle dynamics, which are repetitive using data initially acquired at sampling rate well below Nyquist rates.
