Brief Description

The new U3841, U3851 and U3872 are spectrum analyzers covering 3 GHz, 8 GHz and 43 GHz. They are referred to as Cross Domain Analyzers™ and offer frequency, magnitude, time and phase measurements. Two channels, integrated as standard, enable phase-synchronized RF measurements using a single instrument.

The analyzers can implement cross domain, cross channel and cross vector mathematics in one box.

This new functionality allows quick and easy detection and analysis of electromagnetic interferences of two unknown but correlated radio wave signals. It can measure the phase difference between two signals.

Advantest products can be purchased from Rohde & Schwarz representatives in certain countries. Please check in "Sales Addresses" if your local Rohde & Schwarz representative is also an Advantest representative.
