TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Measurement Setup For Phase Noise Test At Frequencies Above 50 GHz

  Recent semiconductor technologies require more of the frequency range beyond 50 GHz, especially in wideband applications, such as 802.11ad, microwave links, or automotive RADAR. Low phase noise is essential for these applications to work properly, and accurate measurement of phase noise is needed to improve the performance. However, test setups at these frequencies become difficult, especially when cross correlation of two receive paths is needed to suppress additional phase noise.

• 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.

• How To Perform A Radiated Emissions Measurement

  Explore the intricacies of setting up radiated emissions testing with this guide, covering everything from antenna placement and polarization to accurate frequency selection and signal measurement.

• Crowdsourcing Versus Mobile Network Testing

  The need for an objective evaluation of mobile network quality and performance drives two fundamentally different approaches, crowdsourcing, and mobile network testing.

• 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.
