Two amplifiers have been set up for a rating of 600 VA and 70 VA, respectively. The 600 VA version is used for testing standard burdens, while the other one is used as a source for a calibrator for testing test sets for conventional and non-conventional current or voltage transformers. The amplifiers offer the possibility to switch between a voltage mode and a current mode. The bandwidth of the amplifiers covers the range from 16.7 Hz to at least 3 kHz. Different ranges between 80 V to 280 V in the voltage mode, and 2 A to 10 A in the current mode are realized with a transformer-coupled output stage. The gain accuracy is in the order of 1 %, while the stability is better than 0.01 %. The smaller amplifier will be used to set up future measurement systems in the EMRP project \"Non-conventional voltage and current sensors for future power grids\".","PeriodicalId":415488,"journal":{"name":"2016 Conference on Precision Electromagnetic Measurements (CPEM 2016)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116737880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advanced signal processing algorithms provide precise measurements of single period events (i.e. single period of a wave form) for sinusoidal, non-sinusoidal and quasi-stationary signals. The uncertainty for AC current and power measurements of a single period event are <;75 pμ/A and <;200 μW/W. The uncertainty of the phase measurement between two single period events (i.e. voltage-to-voltage, current-to-current, and voltage-to-current) is <;50 μrad. Uncertainties are materially reduced with averaging over multiple periods. This paper describes the architecture and algorithms.","PeriodicalId":415488,"journal":{"name":"2016 Conference on Precision Electromagnetic Measurements (CPEM 2016)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117046458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The radiometer will estimate the noise temperature of a device under test (DUT) based on comparison with room temperature and 77K noise standards. This is a standard physical approach in other NIST microwave radiometers. The radiometer is particularly amenable to performing noise temperature as well as noise parameter measurements for amplifier and transistor characterization. As wireless communications progresses towards millimeter wave systems, noise characterization of related components and subsystems becomes essential.
