VXI-based automatic scalar network analyzer system in 2-118.1 GHz frequency range

Abstract

An automatic scalar network analyzer system in the 2-118.1 GHz frequency range has been designed on the basis of the VXI bus. Features of the system include: wide dynamic range; solid-state synthesized source with 0.3 Hz step and /spl plusmn/5/spl times/10/sup -8/ frequency uncertainty; pure source signal spectrum, with harmonic and nonharmonic spurious suppression of more than 40 dB; calibration with interpolation through the entire frequency range; a convenient user interface; hard copy output to a printer; modular system architecture with flexible options and possible performance expansion; two independent measurement channels with arbitrary choice of measuring parameter (including transmission/reflection), frequency and number of points; available options to 178 GHz and/or with inch-based waveguides according to IEC standards.
