Calibration method for network analyzers

Network analyzers with more than two ports must be calibrated daily for use in electronics, communication engineering and high-frequency technology. This calibration can currently be very time consuming. A new calibration method from PTB mitigates this situation. Here, novel multiport star circuit standards are characterized using a PTB reference calibration (see figure). The network analyzer is calibrated by means of such a calibrated standard applying the least-squares method. (Technology Offer 0456)
Advantages
