Rf Vector Measurement Test-bench for Evaluation of Behavioral Model Accuracy under Realistic Excitation
نویسندگان
چکیده
This paper presents a simple test bench providing RF vector measurements of typical wireless communication system building blocks under realistic signal conditions. The instruments are synchronized by use of an experimental method based on an estimate of the signal path’s time delay. As an example, a complex digitally modulated signal with a carrier frequency of 2.45 GHz was used. The ultimate goal of this test-bench is to deliver accurate measurement data enabling evaluation of the quality of large-signal behavioral models of the measured RF blocks.

Using of Behavioral level AMS & RF Simulation for Validation Test set Optimization
The expansion of Wireless Systems-on-Chip leads to a rapid development of new design and test methods. In this paper, the test benches defined for design validation or characterization of AMS & RF SoCs are first optimized and then re-used for production testing. Although the original validation test set allows the verification of both design functionalities and performances, this test set is no...
متن کاملInvestigation of STATCOM effects on synchronous generator impedance based LOF relay with considering a realistic model for the excitation system of the generator
This paper studies the effects of static synchronous compensator (STATCOM) on synchronous generator conventional loss of field (LOF) protection. To accomplish a comprehensive study, a typical and realistic excitation system is considered for the generator by using the phase-domain generator model available in the real-time-digital-simulator. Using such a system, LOF phenomenon is realistically ...
متن کاملB1 Mapping and Parallel Excitation using Vector Decoupling
Introduction: Parallel RF excitation is a novel technology that can significantly accelerate multidimensional selective excitation, improve RF homogeneity and reduce SAR. High-fidelity excitation requires accurate knowledge of the transmit array B1 sensitivity profiles and a linear RF transmit system. We present an approach using vector decoupling [1] to facilitate measurement of the B1 sensiti...

Anti-cyclic peptide antibodies (CCP/ACPA) are directed towards synthetic citrullinated peptides and are specific markers in diagnosis of Rheumatoid arthritis. This study aimed to compare the values and acuracy of the test in anticyclic citrullinated peptides (Anti-CCP /ACPA) antibodies, rheumatoid factor (RF), C-reactive protein (CRP) and disease activity index (PASI) in early diagnosis of untr...
متن کاملRadio-Frequency-Controlled Urea Dosing for NH3-SCR Catalysts: NH3 Storage Influence to Catalyst Performance under Transient Conditions
Current developments in exhaust gas aftertreatment led to a huge mistrust in diesel driven passenger cars due to their NOx emissions being too high. The selective catalytic reduction (SCR) with ammonia (NH₃) as reducing agent is the only approach today with the capability to meet upcoming emission limits. Therefore, the radio-frequency-based (RF) catalyst state determination to monitor the NH₃ ...
