HP8753E FW 7.74 Calibration Kit File import error

[Ralf HN]

I have a problem with HP8753E FW7.74.

I want to upload a modified VNA Calkit Manager file for a selfmade cal kit with floppy disk to the HP8753E. With state recall comes the error message file has wrong format. The file has the extension .ckm.

Unfortunately also the export of a modified internal user calibration from the device to the floppy disk also does not work. When pressing the save button there is only a short beep and nothing else available.

Saving the settings works. I would be very grateful for support.
