Hello, I am using N5242A PNA-X with 001 option for material measurement with waveguide calibration kit.(X11644A ) using smart cal kit option for NA. I need to ask
1. While performing waveguide calibration, should i connect the 1/4 lambda shim for the through( defined thru) calibration or not. The delay for the standard defined thru option that come on PNA screen is ( 0mm / 0sec). If I add the shim for the thru calibration then should i change/add the value of the delay in the cal kit standards.
2. If shim is added for thru calibration, then what would be the sample holder length in the 85071E material measurement software.

I don't know the PNA-X menus, but for a normal waveguide calibration kit, to perform a 2-port cal, you only need a
* Flush short on port 1
* Quarter wave offset short on port 1 (which in the X11644A you get combining the quarter wave shim and the short)
* Load on port 1
* Flush short on port 2
* Quarter wave offset short on port 2 (which in the X11644A you get combining the quater wave shim and the short)
* Load on port 2
* *Zero length thru.*
If the PNA is telling you a zero delay thru, then I would do as it says, as that is what I would expect. It is what I always do when doing a waveguide calibration. In fact, I have built waveguide cal kits for others, and say they should do that.
The X11644A comes with a precision section of waveguide. The manual tells you to how to verify the calibration by adding that, and putting a short on the end. Then see what the maximum ripple is.

I very much doubt you need the shim. So I would have thought your sample length was just whatever you put between the waveguide flanges.
Note,
1) I don't work for Keysight
2) I don't have a PNA-X
3) I don't have the materials measurement software.
All my suggestions are based on what I know from calibration of much older analyzers.
