5-2 Keysight Technologies 85059A 1.0 mm Calibration and Verification Kit
Performance Verification
NOTE In some cases, the first time a kit is used after being recertified occurs some
time after the actual recertification date. The recertification interval should
begin on the date the kit is
first
used.
Where to Send a Kit for
Recertification

How Keysight
Technologies Verifies
Devices in this 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
