TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Measurement Of The Phase Between Several Signals

  Measurement of magnitude can be done with spectrum analyzers, power meters etc. For a phase measurement, a VNA is the easiest, fastest and most accurate instrument. 

• Wideband Optical Modulator And Detector Characterization: Uncertainties And The Impact On Eye Diagrams/Time Domain Modeling

  Optical modulators and detectors have been characterized and calibrated over the years, but less attention has been given to the optimization of converter measurement uncertainties in a practical user context. Since frequency dependencies of various error mechanisms are different, the wide bandwidths could require procedural changes for optimum results. This paper explores these characterization and calibration processes, as well as the net uncertainties, and their impact on example eye diagram generation.

• Testing A 24-28GHz Power Amplifier Using The 5G New Radio Test Standard

  In this white paper, we will introduce some of the main challenges in test and measurement of a device at mmWave frequencies, with a 26 GHz pioneer band defined for the UK between 24.25 - 27.5 GHz.

• Real-Time Spectrum Analysis For EMI Diagnostics

  This application note examines the different stages of design and testing in regards to test equipment and measurement techniques. It also provides an example of EMI diagnostics using the unique DPX spectrum display for discovery and the frequency mask trigger for signal capture.

• Introduction To Specifying RF/Microwave Power Amplifiers For EMC Testing

  Historically, amplifier selection for Electromagnetic Compatibility (EMC) testing was based mainly on tribal knowledge and information scattered across the EMC industry. This application note provides the EMC test engineer or technician with the information necessary to make the proper decision.
