Connector Sex

Offset Shorts
Choosing Calibration Standards
The connector sex of a 1.0 mm calibration standard can have a significant
effect on its electrical characteristics. Many of the standards in the 1.0 mm
calibration kit have separate standard definitions for male and female
versions. It is very important to use the correct definition for the sex of the
standard you are measuring.
The standard labels which appear in the calibration menus specify connector
sex as "(M)" or "(F)". The parentheses around the sex designator mean that
it refers to the sex of the port to which the standard is connected (not the sex
of the standard itself).
For example:
•
"(M) OPEN" means an open that connects to a male port (in other
words, the open itself has a female connector).
•
"(F) SHORT" means a short that connects to a female port (in other
words, the short itself has a male connector).
•
Whenever a device is described as "M" or "F" without parentheses, the
letter indicates the sex of the device itself.
In the 8510XF, at frequencies above 50 GHz, offset shorts are used in the
place of opens and loads. The "OPEN" category is therefore renamed
"OPEN/SHORT", and the "LOAD" category is renamed "LOAD/SHORT".
The offset shorts that are included in the 1.0 mm calibration kit have
different offset lengths. To distinguish them clearly, each offset short is
assigned a number (1 to 4), and that many rings are engraved on the body of
the device (that is, Short 2 has two rings, and Short 4 has four rings).
The offset shorts have different standard definitions for the versions with
male or female connectors. For example, when using Short 3, the standard
definition to use is "(M) SHORT3", if the device is connected to a male port,
or "(F) SHORT3" if it is connected to a female port.
