As components increase their rate of data processing the Printed Circuit Board is expected to transfer data at ever faster rates to keep pace. Beyond 2 Gb/s the impact of dielectric loss becomes a critical factor in the design process [1]. Agreement of loss measurements between PCB manufacturers and their customer base can be crucial in ensuring that design tolerances are met.
We have developed a calibration technique for Vector Signal Analyzers (VSA) that provides traceability to primary standards. This technique has been implemented using standard commercial equipment. A multisine signal generator provides detailed magnitude and phase stimulus over the instrument bandwidth and a Digital Sampling Oscilloscope (DSO) measures the same multisine waveform. Traceability is...
