Many applications in aerospace and defense as well as in mobile communication require a defined magnitude and phase relation between several signals, for example, to design a smart antenna array and it's distribution network, or to ensure accurate phase alignment between different transmitter or receiver chains of T/R modules. Magnitude can be measured with spectrum analyzers or power meters. For phase measurements, a vector network analyzer is the easiest, fastest and most accurate instrument.This application note shows how to measure the phase accurately between several signals using vector network analyzers of the R&S®ZNA, R&S®ZNB and R&S®ZNBT families.

Frequency converters e.g. in satellite transponders need to be characterized not only in terms of amplitude transmission but also in terms of phase transmission or group delay, especially with the transition to digital modulation schemes. They often do not provide access to the internal local oscillators. This application note describes a method using the R&S®ZNA analyzer family to measure group delay of mixers and frequency converters with an embedded local oscillator very accurately. The key aspect of this new technique is that the network analyzer applies a 2-tone signal to the frequency converter. By measuring the phase differences between the two signals at the input and at the output, it calculates group delay and relative phase.
