1 General Information
Adapter Set Overview
The Keysight 11904S adapter set is designed to give network analyzer systems with 2.4 mm test
ports (such as the Keysight 8510, 8722, and the PNA Series) the ability to perform measurements
on devices with 2.92 mm connectors. The set can be used to achieve calibrated measurements of
2.92 mm devices up to 40 GHz, and 2.4 mm devices up to 50 GHz.
Adapter set contents
The basic 11904S adapter set includes the following items:
– User’s and Service Guide (x 1)
– 2.4 mm to 2.92 mm adapters (x 4)
– 5/16 in, 56 N-cm (5 in-lb) torque wrench for use on the 2.92 mm connectors (x 1)
– Open-end wrench for the 7 mm flats on some of the components (x 1)
Calibration definitions
The calibration definitions are for you to use with your analyzer. Refer to your network analyzer
User’s Guide, or embedded Help for information on modifying the calibration kit standard
definitions.
8510
– 2.92 mm A.3, contains modified standards data to account for the adapters, which are inserted
after a 2.4 mm calibration is performed.
– 2.4 mm A.4, contains calibration definitions for only the 2.4 mm devices.
Adapters (2.4 mm and 2.92 mm)
Like the other devices in the kit, the adapters are built to very tight tolerances to provide good
broadband performance and to ensure stable, repeatable connections.
The adapters are designed so that their nominal electrical lengths are the same, which allows them
to be used in calibration procedures for non-insertable devices (such as adapter removal).
The male 2.4 mm and 2.92 mm connectors are metrology grade. The female PSC-2.4 mm is a
metrology–grade, precision slotless connector. The female 2.92 mm connectors have slotted
contacts and therefore cannot be considered metrology grade. Due to the extremely thin wall of
the 2.92 mm female connector, a slotless metrology grade 2.92 mm connector pair does not
currently exist.
Connector adapter sets documented in this manual
The part numbers provided in this manual are the recommended replacement parts for this set. The
devices in this set should meet the specifications published in this manual.
Equipment required but not supplied
Some items are required or recommended for successful operation of your kit, but are not supplied
with the kit.

Incoming Inspection
To verify the electrical performance of the devices in this set, see Chapter 4, "Performance
Verification".
Check for damage. The foam-lined storage case provides protection during shipping. If the case or
any device appears damaged, or if the shipment is incomplete, refer to the Keysight contact
numbers located at the end of this manual. Keysight will arrange for repair or replacement of
incomplete or damaged shipments without waiting for a settlement from the transportation
company. See “Returning a Kit or Device to Keysight” on page 49.

Keysight 11904S User’s and Service Guide 13
1 General Information
Clarifying the Sex of Connectors
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.
Tab le 1-1 Clarifying the sex of connectors: examples
Terminology Meaning
Short –f– Female short (female center conductor)
Short (f) Male short (male center conductor) to be connected to female port
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.
14 Keysight 11904S User’s and Service Guide
Preventive Maintenance
The best techniques for maintaining the integrity of the devices in the kit include:
– routine visual inspection
– routine cleaning
– proper gaging
– proper connection techniques
All of these 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 20) or from bad connection
techniques, can also damage these devices.
