Vector Receiver

A vector-receiver load pull system utilizes couplers between the DUT and the tuning element(s) which could be Passive or Active to measure the a and b waves.

These a and b waveforms can be mathematically translated to uncover the voltage and current waveforms at the terminals of the device.

As the system allows for accurate measurement of fundamental and harmonic content, this approach removes the reliance placed on accurate and robust pre-calibration of tuners, as the input and output impedances are now measured live during the measurements.
