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 ...
PAM-4, which could be a catalyst for reaching 400-Gb/s Ethernet, will also likely find homes in high-speed serial interfaces such as FibreChannel. Pulse amplitude modulation (PAM) is a way to pack ...
Measurement of average power in a 60Hz circuit (equivalent to V RMS × I RMS × cos(ø)) can be done by sampling the product of voltage and current and averaging. This requires four quadrant ...
Depending on the low-distortion needs of an application, the system engineer can choose from plenty of signal amplifiers. The first step in making the right choice is to understand the typical ...
