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 the kit include:
• routine visual inspection
• cleaning
• proper gaging
• proper connection techniques
All of these techniques are described in Chapter 3 . 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 connection
techniques, can also damage these devices.
When to Calibrate
A network analyzer calibration remains valid as long as the changes in the systematic
