Scattering parameters: reflection coefficient (Sii) on waveguides, real and imaginary. Passive device, one and two port devices, -1 to 1
Absolute expanded uncertainty (k = 2.5, level of confidence 95 %): 0.002 to 0.008
Network analyser
Frequency range: 10 MHz to 67 GHz
Waveguide designation: R70, R100, R140, R220, R320, R400, R620, R900
Uncertainty is dominated by repeatability and device performance. The value estimated here assumes a very repeatable device.
