Measuring the Characteristics of Modulated Non-Linear Devices
Yves Rolain, Wendy Van Moer, Philip Vael · 1999
A flexible and reconfigurable measurement setup for non-linear devices is proposed. It combines the advantages of a reconfigurable instrument and interchangeability of the instrumentation modules. To show the framework capability, the non-linear characterisation of an amplifier in the 900 MHz band under cw and modulated excitation is presented. The spectral regrowth is hereby fully characterised in amplitude and phase.
