Hubner+Suhner adaptors are used to measure applications with QN interfaces
These adaptors support calibration with open standard interfaces, due in part to the same electrical length and the same return loss behaviour of all these adaptors, the swapping method can be utilised
Identical electrical length Fast measurement set-up change: e.g
male to female Measure devices with QN interfaces Precise calibration for phase critical measurements 50Ω, 11GHz
