How Keysight Verifies the 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 NIST (National
Institute of Standards and Technology). 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 calibration device is electrically tested on this system. For the initial
(before sale) testing of the calibration devices, Keysight includes the test
measurement uncertainty as a guardband to guarantee each device meets
the published specification. For recertifications (after sale), no guardband
is used and the measured data is compared directly with the specification
to determine the pass or fail status. The measurement uncertainty for each
device is, however, recorded in the calibration report that accompanies
recertified kits.
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 this kit is traceable to NIST through Keysight Technologies.
Recertification
The following will be provided with a recertified kit:
— a new calibration sticker affixed to the case
— a certificate of calibration
— a calibration report for each device in the kit listing measured values,
specifications, and uncertainties
Keysight Technologies offers a Standard calibration for the recertification of
this kit. For more information, contact Keysight Technologies - refer to
“Contacting Keysight” on page 5-4 .
A list of NIST traceable numbers may be purchased upon request to be
included in the calibration report.
