TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• 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.

• Characterization Of An Amplifier With The Combination Of Network And Spectrum Analysis

  The general characterization of complex DUTs such as amplifiers requires the measurement of several parameters. Thanks to its versatility, the R&S^® ZNL is an economic solution that can characterize a variety of DUTs both via network analysis and spectrum analysis.

• AC-DC Converter Testing Fundamentals

  AC-DC conversion stage in front of any electronic equipment is needed. For this purpose, different solutions exist to convert the higher AC voltage to a lower and safe DC voltage.

• Battery Simulation With DC Power Supplies

  This application note guides users in creating custom battery models for R&S^® NGM200 and R&S^® NGU201 power supplies, enabling gradual battery discharge via QuickArb and data logging, with recorded data adaptable for battery simulation using a provided developer tool.

• Wi-Fi Performance In A House With Two Routers

  Wireless InSite’s Communication System Analyzer provides capabilities for assessing the performance of LTE, WiMAX, 802.11n, and 802.11ac systems. This example investigates WiFi throughput coverage in a house provided by 802.11ac routers operating at 5 GHz using an 80 MHz bandwidth.
