Ripples in waveguide calibration E5063A

After calibrating E5063A using X11664A  kit (composed of FLANN elements) we have ripples in the measurement results. At a smaller device (circulator) we have ripples 0.06 dB peak to peak, at bigger device (waveguide combiner) with potentially bigger cable movement we have ripples up to 0.1 dB peak to peak.


Is it due to calibration residual or due to cable movement? Currently we are using with VNA Maury Stability+ cables .

What can you recommend to change for lower ripples?
