The analyser supports simultaneous phase-coherent signal analysis of two unknown RF signals, this is important when doing phase difference measurements in any RF multi-path application without the need to take out a partial component of the complete transmission path.
The unit can carry out vector calculation of two signals, which can be used for detection of reception problems caused by inter-circuit interferences or by radio wave reflections.
The simultaneously, phase-synchronous measure of two signals can be used for identification of noise sources. It can help to identify the transmission path of interferers in electro-vehicles.
Typical applications include cross polarisation discrimination in satellite communication, phased array / radar antenna measurements, EMI and astrophysical measurements at inconvenient ambient noise conditions, antenna diversity or multi-path receiver measurements, smart antennas.
There are three Advantest models available from Rohde & Schwarz: U3841 (2 x 3GHz), U3851 (2 x 8GHz), U3872 (2 x 43GHz).
