A PC with sound card as an audio waveform generator, a two-channel digital oscilloscope and a spectrum analyzer
free download

The availability of inexpensive PC sound cards that can simultaneously play and record stereo digital audio files permits a single PC to function as both a signal generator and as a dual-channel recording digital oscilloscope . When the input and output of a linear analog

Acquisition clock dithering in a digital oscilloscope
free download

When half frequency component of the input signal is greater than half the sample time aliasing can occur. When the oscilloscope is equivalent time sampling, signals that are subharmonics of the sample clock will be poorly displayed. In the HP 54645A/D

Compensation of sampling oscilloscope trigger jitter by an in-phase and quadrature referencing technique
free download

An improved time-referencing technique, realised using commercial microwave components, has been used to improve the measurement jitter performance of a sampling oscilloscope . The limiting residual rms jitter is approximately 185 fs. The measured peak-to

Design and implementation of multifunctional virtual oscilloscope using USB data-acquisition card
free download

Based on virtual instrument technology, a multifunctional virtual oscilloscope was designed by using NI USB data acquisition card and LabVIEW software. Its functions included channel selection, signal adjustment, waveform display, time domain analysis, frequency domain

Correcting sampling oscilloscope timebase errors with a passively mode-locked laser phase locked to a microwave oscillator
free download

In this paper, we describe an apparatus for cor-recting the timebase errors when calibrating the response of an equivalent-time sampling oscilloscope using a passively modelocked erbium-doped fiber laser that is phase locked to a microwave signal generator. This enables

Systematic error of the nose-to-nose sampling- oscilloscope calibration
free download

We use traceable swept-sine and electrooptic-sam-pling-system-based sampling- oscilloscope calibrations to measure the systematic error of the nose-to-nose calibration, and compare the results to simulations. Our results show that the errors in the nose-to-nose
