The Cross Domain Analyzer U3800 Series is a vector and spectrum-signal analyzer with built-in two-channel RF input function. This is the industry’s first metrology tool that enables comparative measurement/analysis of the signals from two channels on the basis of their time, amplitude, phase, and frequency domains by simultaneous and synchronized measurement.

This Cross Domain Analyzer has the following features and functions:

● Two-channel RF input and wide frequency range

● The best-in-class time domain analysis bandwidth of 40 MHz

● Vector operation that allows composition/decomposition

U3800 Series allow the users to easily measure and analyze multiplexed/mixed/interfered www.abb-drive.com signals so that complex signal analyses that are conven

tionally difficult to perform, such as multipath analysis, electromagnetic field decomposition, and inter-circuit interference, can be carried out.

U3800 Series consists of analyzers applicable to a wide variety of fields such as broadcasting, telecommunication, and EMC.

A new field of RF measurement—Concept of Cross Domain

”We want to freely compare two RF signals in different analytical domains so that measurement and comparison of two signals that change with time, such as those in transient phenomena, modulating waves, and EMC noise can be achieved by means of a vector operation.” In order to satisfy such requirements, we have developed a measurement equipment that can easily measure, compare, and

analyze true momentary signals, which is difficult in the case of conventional measurement equipments, by equipping it with a two-channel phase-locked loop vector measurement function and operation function.

Key performance of the U3800 Series

● World’s first two-channel simultaneous/parallel measurement in the analysis bandwidth (maximum: 40 MHz)

● Vector comparison with high sensitivity and wide dynamic range (pre-amplifier equipped as standard)

● U3800 Series to support 9 kHz to 43 GHz of measurement frequencies
