Performance Verification
Introduction
Introduction
The performance of your verification kit can only be verified by returning the kit to Keysight
Technologies for recertification. The equipment required to verify the specifications of the
devices in the kit has been specially manufactured and is not commercially available.
How Keysight Verifies the Devices in Your Kit
Keysight verifies the specifications of these devices as follows:
1. The residual microwave error terms of the test system are verified with precision airlines and
shorts that are directly traced to the National Institute of Standards and Technology (NIST).
The airline and short characteristics are developed from mechanical measurements. The
mechanical measurements and material properties are carefully modeled to give very
accurate electrical representation. The mechanical measurements are then traced to NIST
through various plug and ring gages and other mechanical measurements.
2. Each device is electrically tested on this system. The measurement uncertainty for each
device is recorded in the calibration report that accompanies every kit.
These two steps establish a traceable link to NIST for Keysight to the extent allowed by the
institute’s calibration facility. The specifications data provided for the devices in the kit is
traceable to NIST through Keysight Technologies.
