TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Selecting Your Next Oscilloscope: Why Digital Triggering Matters

  Many people tend to overlook the importance of triggering while selecting an oscilloscope, but it's actually a crucial factor to consider. Digital triggering can offer some significant advantages.

• Combining On-Wafer VNA And Spectrum Analyzer Measurements

  This app note describes how S-parameters and spectrum analysis can be monitored simultaneously from 70 kHz to 110 GHz using the VectorStar ME7838A, the Spectrum Master MS2760A, and the Anritsu MN25110A W1 coaxial precision directional coupler.

• 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.

• Design And Implementation Of A Miniature X-Band Edge-Coupled Microstrip Bandpass Filter

  Microwave bandpass filters are the fundamental component used in many RF/microwave applications to eliminate interference from signals operating at nearby frequencies. This application note presents a straightforward and largely nonmathematical method for designing an edge-coupled, bandpass filter for X-band operations with a combination of filter synthesis, closed-form edge-coupled transmission-line models, and EM analysis using the Microwave Office circuit simulator within Cadence AWR Design Environment software.

• eUICC Profile Handling

  This application note describes the eUICC compliance and remote eUICC provisioning test solution based on R&S CMW500/CMW290 and COMPRION eUICC Profile Manager software tool with focus on M2M devices.
