If your PNA-X is running recent firmware, then it will support a .xkt file. A .xkt file is supplied on a USB stick. If however your firmware is very old, then it will not support the .xkt file format. The best solution, which will give you bug-fixed and enchancements, is to just update the firmware. But if this is not possible, or you don't wish to update the firmware, then please let us know and we will generate you a .ckt file which your PNA will read. We do not put a .ckt file on the USB stick on every kit we sell, as making this is requires some manual processes that we can not automate.
If you wish to use one of our kits on a PNA-X, then follow the instructions for configuring a Agilent/Keysight PNA series vector network analyzer. The modern PNA and PNA-X take the same file .xkt format. Each kit is shipped with a .xkt file, which works for FieldFox, PNA and PNA-X. Older PNAs need a little more work, but are easy to set up.
Kirkby Microwave do not own a PNA-X, but one of our customers in the USA has their N5247A PNA-X set up to allow remote access - mainly for technical support from Keysight staff. However, they have given us permission to log in too, when the instrument is not in use, so we can check that calibration kit files have loaded properly.
