Waveguide Sample Holder Measurement Reproducibility (X/R Band, PP)

Measurement Results

  • Measured five times, recalibrating the system before each measurement.
Waveguide sample holder X-band measurement reproducibility for polypropylene, Dk frequency characteristics.
Waveguide sample holder X-band measurement reproducibility for polypropylene, Df frequency characteristics.
Waveguide sample holder R-band measurement reproducibility for polypropylene, Dk frequency characteristics.
Waveguide sample holder R-band measurement reproducibility for polypropylene, Df frequency characteristics.

Key Point!

  • Excellent reproducibility, with variation below 1%.
  • Similarly high reproducibility is achieved across multiple products.

When measuring materials, reproducibility, or how consistently the same result can be obtained, is a very important point. High measurement reproducibility allows R&D teams to detect even slight differences between materials and apply those findings to the next prototype. In manufacturing, it also enables stable sample monitoring and more accurate quality control.
Here, repeated measurement results for polypropylene are shown. The system was recalibrated before every measurement, so the results are close to what would be obtained in practical measurement workflows.
