The Bird VIP System is a tool for measuring voltage, current and the phase angle between these parameters in complex applications. The VIP System is Bird Technologies' solution to the semiconductor market to provide more information than traditional VI probe instruments . Each calibrated system is comprised of a sensor that attaches in-situ in the RF feed line, a receiver that performs the data conversion and communicates to your workstation, and a data cable that connects the sensor to the receiver.

Using a streamlined architecture, the VIP System is able to measure and report voltage, current, and phase angle at multiple fundamental, harmonic and intermodulation frequencies. With this data, power and impedance are calculated at each frequency, giving users the ability to identify small discrepancies that may make the difference between a successful and a failed process. This makes the VIP System an incredible tool for repeating high precision processes.
