VNA Tools II is free and supports most of the Vector Network Analyzers (VNAs) in today’s market. The software simplifies your tasks of generating accurate measurement uncertainty and vindicating metrological traceability. The software is ideal […]
by Murat Celep In the wide band radiometer, it is necessary to use more than one low noise amplifier (LNA) because of their narrow band characteristic. The change in the gain of the LNAs with […]
by Michael Schwartz Many calibration labs are starting to calibrate power sensors or looking to increase their capabilities and frequency range. In this Metrology 101 we are hoping to help some calibration labs improve their […]
by Bart Caswell In 2013 and 2014, the U.S. Army Primary Standards Laboratory piloted a six-laboratory intercomparison (ILC) of phase noise measurements using a Fluke 9640A-LPN signal generator as the test article. The article was […]
EVERETT, Wash., Aug. 6, 2014 – Fluke Calibration introduces the 96270A and 96040A Low Phase Noise RF Reference Sources, which simplify RF and microwave calibration systems by replacing many of the instruments and accessories in […]
by Jesse Morse If a person making a dc or low frequency measurement fails to select the proper cables, or to properly connect the shields the traceability chain for that measurement can be violated. This […]
The Metrology 101 article from the Jul-Sep 2013 issue, “Testing Linearity on the Agilent E441xA Power Sensors,” has been updated online. The upper and lower readings are incorrect in the printed version. An Excel spreadsheet […]
by Michael Schwartz Today’s new high dynamic range power sensors are not built the same as the older generations of sensors. Older generations of power sensors only had a correction table for their frequency response. […]
