TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Testing For Coexistence In Crowded And Contested RF Environments

  In this paper, we review some of the key research, development, test and evaluation (RDT&E) challenges that arise when developing and deploying systems that need to operate in congested and/or contested RF environments.

• Circuit Models For Plastic Packaged Microwave Diodes

  This paper reports on the measurement and establishment of circuit models for SOT-23 and SOD-323 packaged diodes. Results indicate that the 1.5 nH estimate for the SOT-23 is a useful result, as is 1.2 nH for SOD-323 single packaged diodes. It was also determined that the effective inductance of the SOT-23 may be reduced to approximately 0.4 nH by adding a second bond wire and modifying the microstrip line. Other lead configurations, including parallel bond wires and common cathode configurations, were also studied.

• Compact Solution For Network Analysis In The mmWave Range

  The R&S^® ZNA vector network analyzer with integrated LO output and direct IF input options is a simple, cost-effective solution for 2-port and 4-port measurements using Rohde & Schwarz mmWave converters.

• Load Transient Response – Enhancing Loop Stability Testing

  Ensuring stability in power supply design requires validating switching converter stability through frequency loop and load transient responses, aided by modern oscilloscopes for visualizing PWM signals and identifying converter effects.

• Crowdsourcing Versus Mobile Network Testing

  The need for an objective evaluation of mobile network quality and performance drives two fundamentally different approaches, crowdsourcing, and mobile network testing.
