The Fast Fourier Transform (FFT) converts time domain waveforms, acquired in an oscilloscope, into frequency domain spectra. This allows the oscilloscope to display the same kind of information usually supplied by an RF spectrum analyzer.

Designers of high-speed serial data systems can characterize the level of crosstalk present on signals by using SDAIII-CompleteLinQ features including the Reference Lane, LaneScape Comparison Mode and the Vertical Noise and Crosstalk package to analyze waveforms in both aggressor-on and aggressor-off transmitter configurations. This application note provides information on how to perform this analysis and to understand and compare noise and jitter results.

The Universal Serial Bus (USB) was initiated in 1996. Since then it has undergone major revisions to levels 1.1, 2.0 and now 3.0. Each revision substantially increased the rate of data transfer.

Settling time measurements require that the scope determine how long it takes for an input signal to settle to within a specified tolerance of a fixed voltage level. Since the input signal may make several crossings of the threshold it requires the ability to look at the accumulated time to a final crossing. Using track functions allows a scope to determine when the final crossing has occurred.

The data busses in aircraft and spacecraft require very high quality in transmission and reception since proper communication of commands and data are crucial to operation. The ARINC 429 standard used predominately in commercial aircraft and the MIL-STD-1553 bus used in military avionics and space vehicles (military and commercial) have some common characteristics as well as important differences. This paper will give useful examples of how to view, test and troubleshoot these busses using digital oscilloscopes.
