Use Proper SMA Connector Care and Connection Techniques
Good connections are essential for accurate calibrations and measurements and
require a skilled operator. The most common cause of measurement error is poor
connections.
SMA connectors will mate with 2.92 and 3.5 mm connectors. However, a
damaged SMA connector, or a used SMA connector with a slightly bent pin can
destroy a 2.92 or 3.5 mm connector. In SMA connectors, the center pin connects
first, before the threads. If an SMA pin is bent or off-center for any reason, then
the pin will make contact with the 2.92/3.5 mm female contacts which are
unsupported as an air dielectric is used, and the female contact may be pushed
out of place.
