THE PRECISION AUTOMATED SCALAR NETWORK ANALYZER. THE INTEGRATION OF DIGITAL SIGNAL PROCESSING AND PRECISION AIRLINE TECHNIQUES

摘要

Microwave Network Analyzers have errors introduced by the complex network parameters of both the measurement devices and the device-under-test. For over a decade, the phasor analyzers have attempted to characterize the measurement devices and to correct the measurement errors. Both calibration procedures and software continue to be developed for this error correction. Now it is possible to make these r.f. error corrections with the scalar network analyzer. This is made possible by using lengths of precisely controlled impedance transmission line.
