Clarifying the Terminology of a Connector Interface
In this document and in the prompts of the PNA calibration wizard, the sex of cable connectors and adapters
is referred to in terms of the center conductor. For example, a connector or device designated as 1.85 mm
–f– has a 1.85 mm female center conductor.
8510-series, 872x, and 875x ONLY: In contrast, during a measurement calibration, the network analyzer
softkey menus label a 1.85 mm calibration device with reference to the sex of the analyzer's test port
connector—not the calibration device connector. For example, the label SHORT(F) refers to the short that is
to be connected to the female test port. This will be a male short from the calibration kit.

A connector gage is referred to in terms of the connector that it measures. For instance, a male connector
gage has a female connector on the gage so that it can measure male devices.
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
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
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.
Change in the environment (especially temperature) between calibration and measurement is the major
