Bird Diagnostic System (BDS2)

The Bird Diagnostic System (BDS2) 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 BDS2 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. With the ability to make measurements post-matchbox, the BDS2 uncovers signal characteristics that are not visible to traditional test equipment pre-matchbox.

Using sophisticated parallel signal processing, the BDS2 is able to simultaneously measure and report voltage, current, and phase angle at multiple fundamental, harmonic and intermodulation frequencies. A robust frequency tracking algorithm is employed to guarantee accurate measurements are made under very dynamic signal conditions. 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 BDS2 an incredible tool for researching new RF technologies and repeating high precision processes. The BDS2 is compatible with existing BDS sensor and cable installations.
