TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Measurement Of The Phase Between Several Signals

  Measurement of magnitude can be done with spectrum analyzers, power meters etc. For a phase measurement, a VNA is the easiest, fastest and most accurate instrument. 

• 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.

• 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.

• Accurately Measure Your UWB Device's Time Of Flight

  The R&S®CMP200 radio communication tester together with the R&S®CM-Z300A time of flight kit provides an accurate setup for time of flight measurements – in validation, calibration and certification.

• Basic Bulk Current Injection Testing

  Bulk current injection (BCI) testing is a conducted susceptibility procedure that uses an injection current probe. This paper provides an example of BCI testing, covering all steps, including gathering the required equipment, pre-calibration procedures, injection testing procedures, and safety precautions.
