Bird Diagnostic System (BDS)
BDS Logo

The Bird Diagnostic System (BDS) is a revolutionary tool for measuring voltage and current in complex applications. Where repeatability of sensitive RF measurements is important, such as during the processing of silicon wafers, the BDS provides never-before seen data. Each 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 calibrated data cable that connects the sensor and receiver.

Using a streamlined architecture, the BDS 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 BDS an incredible tool for researching new RF technologies and repeating high precision processes.
