TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Understanding Pulsed Phase Noise Measurements

  This application note focuses on phase noise measurements for pulsed RF carriers such as those used for radar systems. It addresses some of the physical limitations relating to pulsed phase noise measurements and introduces new testing capabilities.

• Application Note: Measuring Video Feedthrough in Pulsed Signals Video feedthrough is a very misunderstood term, which is used in the specification of pulse performance for microwave synthesizers.
• How To Generate And Measure Noise Power Ratio (NPR) Signals

  In order to generate noise power ratio stimulus signals and to measure the resulting noise power ratio of a device under test (DUT), Rohde & Schwarz offers the Noise Power Ratio (NPR) as an add-on tool for WinIQSIM / WinIQSIM2™ software. This NPR measurement technique drastically reduces measurement time compared to classic gain wobbling, and is able to characterize the linearity of a wideband amplifier over a custom frequency range. This application note provides an overview of the software, its features, hardware and software requirements, installation, parameters, and more.

• Speeding Up Reflection Measurements On Antenna Systems

  Reflection measurements are a common way of assessing antenna system performance. When a minimum amount of the transmitted signal is reflected, it indicates that the transmission energy can reach the intended coverage. Undesired high reflection causes the system to be inefficient and can damage components. This application note presents solutions for aiding fast and efficient reflection measurements on antenna systems to get it right the first time.

• Measuring RF Levels At Multi-Signal Sites By Narda Safety Test Solutions - An L-3 Communications Company
  The density of systems operating from a single tower or rooftop location is increasing every year. This complex signal environment makes it extremely difficult to accurately determine whether the radiation present at the overall site is in compliance with current standards. Probes with shaped frequency response curves, along with RMS detection, make compliance with FCC guidelines more accurate in complex multisignal measurement environments...
