Calibration Kits Documented in This Manual
Calibration Kits Documented in This Manual
This manual applies to any 85050B calibration kit whose serial number is listed on the
title page. If your calibration kit has a different serial number prefix, refer to the
"Calibration Kit History"
section below for information on how this manual applies.
Calibration Kit History
This section describes calibration kits with serial number prefixes lower that the ones
listed on the title page.
85050B Kits with Serial Prefix 3027A
These calibration kits did not have the calibration definitions disk to support the Agilent
8510C network analyzer. The part numbers provided in this manual are the recommended
replacement parts for these kits. The devices in these kits should meet the specifications
published in this manual.
Preventive Maintenance
The best techniques for maintaining the integrity of the devices in the kit include:
• routine visual inspection
• cleaning
• proper gaging
• proper connection techniques
All of these are described in
Chapter 3 , "Use, Maintenance, and Care of the Devices."
Failure to detect and remove dirt or metallic particles on a mating plane surface can
degrade repeatability and accuracy and can damage any connector mated to it. Improper
connections, resulting from pin depth values being out of the observed limits (see
Table 2-2
on page
2-5) or from bad connection techniques, can also damage these devices.
When to Calibrate
A network analyzer calibration remains valid as long as the changes in the systematic
error are insignificant. This means that changes to the uncorrected leakages (directivity
and isolation), mismatches (source match and load match), and frequency response of the
system are small (<10%) relative to accuracy specifications.
