TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • Directivity And VSWR Measurements: Understanding Return Loss Measurements

    The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.

  • Verifying The Clock Source

    In order to select or develop a clock generator to use in your design or to ensure that the supplied system clock has the proper performance, you'll need to consider phase noise, jitter, wideband noise and spurs as performance indicators.

  • 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.

  • Speeding Up Reflection Measurements On Antenna Systems

    Reflection measurements are a common way of assessing antenna system performance. When a minimum amount of the transmitted signal is reflected, it indicates that the transmission energy can reach the intended coverage. Undesired high reflection causes the system to be inefficient and can damage components. This application note presents solutions for aiding fast and efficient reflection measurements on antenna systems to get it right the first time.
