G'day Jim,
You are quite right of course.
When I wrote the reply to Don I had only just finished reading his referenced Keysight/Agilent/HP document.
I meant to put in a comment that the document was specifically referring to Metrology grade measurements but my head was still spinning from the degree of detail in the document.
It certainly made extremely interesting reading having spent some time in development labs in past lives.
Connector Savers are a real godsend to the fabulous NanoVNAs and TinySAs currently available to us these days. They are the best accessory you can buy for your instruments.
It is interesting also that HP made a range of Connector Savers and Adapters available and characterised the effect they could/would have on measurements.
Cheers...Bob VK2ZRE
And the cool thing is, with the connector saver, the effects of the saver are incorporated in the calibration. They're so short I doubt there's any interpolation or other issues.
