when the problem occurred (such as calibration or measurement)
Recertification of ECal Modules
The suggested interval for recertification is 12 months. After reviewing the
results of the initial recertification, you may establish a shorter interval that
reflects greater use and wear of the module.
Where to Send a Module for Recertification
Contact Keysight for information on where to send your kit for recertification.
See “Contacting Keysight” on page 1-23. Refer to “Returning Devices to
Keysight” on page 1-23 for instructions on the preparation of returning the
device.
How Keysight Verifies Your ECal Module
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 or low frequency resistance 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 module is electrically tested on this system to the specification listed
in Chapter 5, “Specifications and Characteristics.”
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 module are traceable to NIST through Keysight Technologies.
When transporting the module, use original or comparable packaging.
Only Keysight calibration laboratories use the most accurate reference
standards - directly traceable to national and international primary
standards - to calibrate ECal modules to their warranted specifications.
Calibration services performed by unauthorized calibration service
providers will cause ECal modules to perform substantially below
specifications. Keysight is not responsible for the poor performance of ECal
modules that are calibrated by such unauthorized calibration service
providers.
