Accelerate TDR Measurements with Electronic Calibration
by John Dorighi and Rob Sleigh An important consideration for improving the accuracy of time domain reflectometer (TDR) measurements is user calibration. A TDR user calibration is performed to correct for systematic instrument errors along […]
Calibrating a UUT on a Remote Computer Using Fluke MET/CAL®
by Michael Schwartz Current and next generation test equipment will be modular and tightly coupled with a computer’s operating system. Calibration labs have to be highly dynamic supporting all the measurement test systems turned in […]
1mW Power Sensor Calibration with Vector Mismatch Corrections Based on the Direct Comparison Method
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 […]
Analyzing the Effects of Reducing the Ending Zero Versus Ignoring the Trailing Zero on Measuring Instruments Used for Force Calibration
by Henry Zumbrun Differing opinions are found within the ASTM E28 sub-committee regarding the proper treatment of the trailing zero following the removal of an applied force. The ASTM E28 committee is responsible for the […]
Documentation & Document Control
by Kenneth Parson There is an old saying, “Say what you do” and “Do what you say. This saying is the essence of the whole matter of laboratory management, operation and accreditation. I always like […]
Report of an Interlaboratory Comparison of Phase Noise
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 […]
