ADVANTEST U3841 Cross Domain Spectrum Analyzer

ADVANTEST U3841 Cross Domain Spectrum Analyzer

OVERVIEW

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 signals so that complex signal analyses that are conventionally 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.

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 3 GHz Cross Domain Analyzer U3841: 9 kHz to 3 GHz 8 GHz Cross Domain Analyzer U3851: 9 kHz to 8 GHz 43 GHz Cross Domain Analyzer U3872: 9 kHz to 43 GHz

Main Functions and Features

Dual-channel RF input:

The U3841 provides a dual-channel RF input function, which enables users to process two RF signals simultaneously, facilitating complex signal analysis.

Wide Frequency Range:

The analyser's frequency coverage ranges from 9 kHz to 3 GHz, making it suitable for a wide range of wireless communication, RF analysis and EMC testing scenarios.

Simultaneous measurement and analysis:

With the simultaneous measurement function, the U3841 is able to compare measurements and analyse signals from two channels in the time, amplitude, phase and frequency domains, which is at the heart of its cross-domain analysis capabilities.

High sensitivity and wide dynamic range:

Equipped with a preamplifier with high sensitivity and wide dynamic range, this enables the U3841 to accurately capture and analyse weak signals.

Vector Operation & Combination/Decomposition:

The U3841 supports vector operation, allowing users to decompose and combine components of a signal, facilitating in-depth analysis of the signal's internal structure and characteristics.

Multi-Domain Applications:

The analyser is suitable for use in a variety of fields such as broadcasting, telecom and EMC, and is capable of responding to a wide range of complex signal analysis needs.
