TCS50 Calibration Substrate

An S-parameter calibration substrate with short, open and load standards for vector network analyzer. 

The substrate supports all Agilent PNA and ENA calibration to remove probe and probe tip contact errors. It allows users to move the measurement reference point all the way to the probe tip. This substrate standard can also be used to set impedance reference for Agilent ENA to within 0.5% accuracy.

For S-Probes with probe pitches larger than 1.0 mm, please contact PacketMicro to order TCS50 substrate, which has long patterns to support wider pitches and costs $400, same as TCS70.
