General Information
Clarifying the Terminology of a Connector Interface
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 this kit include:
• routine visual inspection
• cleaning
• proper gaging
• proper connection techniques
All of the above 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 2-4 ), or from bad connections, can also damage these devices.
