Functional Description

A high-frequency step signal is applied to the coupon or PCB. Up to 16 transmission lines can be tested via spring loaded needles by using a high-performance multiplexer unit.

The setup of the coupon (line type, goal impedance, tolerances) is assembled automatically by the testing program which is run for each coupon, reducing the measurement duration to only a few seconds. The testing program as well as the Gerber production files can easily be generated with the included coupon generator.

The testing adapter provides a single slot for the coupon, which is pressed to the test fixture by closing the adapter. This guarantees a highly reproducible contact between spring-loaded needles and tested transmission lines.

Immediately after closing the adapter the measure­ment is started ensuring a fast exe­cution time. The completion of the measurement is signaled to the user and the coupon can be removed.

The impedance data is automatically saved and immediately ready for use as e.g. creating a PDF-report.
