Downloads for the Kirkby Microwave 85054 type-N calibration kit for HP/Agilent 8719, 8720 and 8722 series instruments

8720ES VNA

Models without floppy disk drives (8719A, 8719B, 8719C, 8720A, 8720A, 8720B, 8720C, 8722A, 8722B and 8733C)

If you have an early 8720 instrument without a floppy disk, then the easiest way to install the coefficients is to have a PC with an HP/Agilent or National Instruments GPIB card, install the VNA Cal Kit Manager 2.1. Then load the file 85054.ckm in the software and copy to the 8719, 8720 or 8722 over the GPIB bus.

Another way, which is a bit more tedious, but works very well, is to enter the coefficients from the front panel. The coefficients are given at the bottom of this page.

Models with floppy disk drives (8719D, 8719ES, 8720D, 8720ES, 8722D and 8722ES)

If you have an 8719, 8720 or 8722 with a floppy disk, then you can use the method above using the VNA Cal Kit Manager 2.1 software, but there is an easier way.

It is easiest to use a floppy disk. You can either order the disk with the 85054 kit, or if you have lost the disk, just download the file and write the contents to a floppy disk. There are a number of USB based floppy disk drives available, so you don't need a PC with a floppy disk drive.

Once you have the files on a floppy disk, recall the contents of the disk.

The coefficients

Here are the coefficients for the 85054 kit in the format used by HP/Agilent on the 8719, 8720, 8722 series. You can enter these directly from the front panel of the instrument if you wish.
