TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Four Practical Applications Using An Electronic Load

  This article presents four tips on how to test with electronic loads and illustrate the flexibility and usefulness of a DC electronic load. 

• 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.

• 5G New Radio Over-The-Air Base Station Receiver Tests

  This application note describes all mandatory RF receiver tests, according to the Release 16 (V16.3.0). It also offers a brief introduction about the different R&S OA antenna test solutions and how they are applicable for base station conformance testing.

• Ensuring Test Site Compliance for Radiated Emissions With Normalized Site Attenuation

  This application note provides a synopsis of Normalized Site Attenuation (NSA) and Reference Site Method measurements which indicate a challenging but important aspect of radiated emissions measurements on an OATS, SAC, or FAR.  

• Field Probe Correction Factors

  To better achieve accurate field level measurements, it is helpful to have an understanding of field probe calibrations, the factors generated, and what’s presented as data during testing. This application note presents how to utilize the factors presented for inclusion into test data, how to generate composite measurements, and why calibrations are performed at selected frequencies.
