  • Page 7: General Information

    Calibration Kit Overview This waveguide calibration kit is used to calibrate network analyzer systems (such as the Keysight 8510, 872x, or PNA series). With the calibration data properly loaded in the network analyzer and a measurement calibration completed, systematic errors are minimized.

  • Page 8: Equipment Required But Not Supplied

    The 8510 network analyzer is no longer being sold or supported by Keysight. However, you can download the 8510 class assignments and standard definitions from Keysight’s Calibration Kit Definitions Web page at http://na.support.keysight.com/pna/caldefs/stddefs.html.
