Description
The S93083A includes the scalar mixer/converter plus phase (SMC+Phase) measurement class that provides fully calibrated conversion gain/loss, relative phase, and absolute group delay measurements of mixers and converters without the need for reference or calibration mixers. Eliminating the calibration mixer requires a U9391C/F/G comb generator and an external DC power supply. A vector mixer/converter measurement (VMC) class is also included for measuring the phase difference between multiple paths or devices, or for measuring phase shifts within a device. Using VMC or the comb-generator-based calibration for SMC+Phase requires an instru¬ment with a configurable test set (i.e., has front-panel RF loops). For units without front-panel loops, SMC+Phase can be used with an external calibration mixer. The S93083A provides an intuitive and easy-to-use user interface for setting up mixer and converter measurements, with single or dual conversion stages. It can control the analyzer’s built-in source(s) as well as external signal generators for use as LO signals. The S93083A is a superset of S93082A. S93083A is compatible with S93084A, which enables measure¬ments of converters with internal LOs.
