The Aim
System testing of ET requires a complex test and measurement environment, which measures the performance of the ET power supply both with a resistive load, and in conjunction with an RF PA. Nujira had developed an in-house test and measurement system to validate the performance across multiple RF frequency bands, power levels, and test waveforms.
The aim of the project was to optimise the software used to test Nujira’s leading product, the envelope tracking power supply modulators which power energy efficient 4G cellular terminals, base stations and digital broadcast transmitters. Written in LabVIEW.
