The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

Oscilloscopes often include the ability to cross plot the data from two waveforms using X-Y displays. These displays find applications in switched-mode power measurements, baseband ...

Keysight Technologies, Inc. introduced measurement software designed to help engineers quickly and accurately characterize PAM-4 (pulse amplitude modulation with four amplitude levels) signals using ...

Many of today's high-speed serial designs use embedded clocks to avoid routing and timing issues involved with separate data and clock signals and to free up precious real estate on board designs.

Spread spectrum clocking (SSC) is used in many computer interfaces such as PCI Express and Serial ATA to improve the EMI performance of the interface. It takes the form of frequency modulation (FM) of ...

Called 8650HD, two 65GHz channels can be operated though 1.85mm 50Ω connectors, or it can be switched to four 33GHz channels. It is part of the 8000HD family of scopes, with six models from 20 to ...
