This paper analyzes and accurately models the complex noise behavior of vector network analyzers (VNAs) when measuring large-mismatch devices and subsequently shows how the VNA measurement noise performance is enhanced through implementation of a high-speed, broadband, active RF interferometer module. The presented VNA noise model provides a solid framework, benchmarked by measurement data, to analyze existing RF interferometer approaches. The performance improvement of the proposed interferometer implementation is then benchmarked in terms of magnitude and phase stability of the renormalized impedance level. A test bench employing the novel add-on RF interferometer module is presented and demonstrated to achieve high-speed cancellation of the scattered wave over a broad frequency band. The first experiment shows ultralow noise in a 1-18 GHz broadband measurement of co-planar waveguide 0.5-and 5-k impedance standards. Employing the proposed hardware setup improves the noise uncertainty for the 5-k impedance standard by a factor of 8 and 20 at 1 and 18 GHz, respectively. In the second experiment, a factor of 2 height-resolution enhancement is achieved in a scanning microwave microscope when the RF interferometer module is added to the instrument.

“…According to Luca Galatro in (Galatro, Mubarak, & Spirito, 2016), The relationship between conceptions of learning, approaches to learning and learning outcomes is not, however, necessarily straightforward. discuss the apparent paradox in the relationship between conceptions of and approaches to learning, and the learning context, in so far as the literature suggests both that conceptions and approaches are stable yet they can be influenced by the learning environment.…”

“…discuss the apparent paradox in the relationship between conceptions of and approaches to learning, and the learning context, in so far as the literature suggests both that conceptions and approaches are stable yet they can be influenced by the learning environment. Marco Spirito in (Galatro et al, 2016) has developed an interactive systems model of teaching and learning to map how students' general conceptions of and approaches to learning interact with characteristics in the Considerable research now supports the various relationships posited in the model. For instance, some educational practices (presage) have been identified as encouraging surface learning strategies (process).…”

“…For instance, some educational practices (presage) have been identified as encouraging surface learning strategies (process). In turn, research has also demonstrated that specific surface learning strategies (process) typically result in low-level learning outcomes (product), while deep learning strategies lead to cognitively complex performances Marco in (Galatro et al, 2016). Furthermore, when there are differences among students in their general approaches to learning (presage), changes to assessment procedures in a given situation (presage) will lead to changes for all students in their use of deep versus surface learning strategies in that situation (process), but the relative strength among students in their use of deep versus surface modes of operation will remain constant.…”

This research focuses on student perception about how to prepare to understand the use of types of references (anaphoric, cataphoric, and exophoric reference) in the Descriptive text. The objectives of this research are to find out what the types of references that many used in Descriptive text and how many types of references for all paragraph in Descriptive text. The method used in this research is a descriptive qualitative method. The researcher got the data from document analysis namely in the Descriptive text about Artikel. The result from this research are the result from the tenth paragraph of the Descriptive text that has already done to analysis, there are 6 anaphoric reference, 6 cataphoric and in this article contains an understanding of a text and a concept so students can understand about the material.
