Validating a Calibration
— The System Verification Procedure is also a method for verifying the 
performance of your analyzer.
— Verification kits use accurately known standards with well defined 
magnitude and phase response. These kits include precision airlines, 
mismatch airlines, and precision fixed attenuators.
— Each verification kit standard is measured precisely by Keysight’s accredited 
test laboratory. The measurement data and uncertainty of each standard 
are provided in each kit on a disk or USB storage drive.
— Verification kits may be re-certified by Keysight. Contact Keysight for 
information about ordering verification kits - see “Contacting Keysight” on 
page 1-23.
For detailed information on using your analyzer’s built-in System Verification 
Procedure, refer to the appropriate service guide or online Help. To use the 
internet to view the ENA, PNA, or PXIe online Help, use the steps listed in 
“Finding More Information on Performing a Calibration” on page 3-10.
