This chapter provides you with an overview of the 11904S adapter set.

1 General Information
12 Keysight 11904S User’s and Service Guide
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.

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.
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.
Table 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

General Information 1
Keysight 11904S User’s and Service Guide 15
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.

Environmental Requirements
The Keysight 8497K Attenuator is designed to fully comply with Keysight Technologies’ product
operating environmental specifications as shown in Table 2-1.
Temperature — what to watch out for
Changes in temperature can affect electrical characteristics. Therefore, the operating temperature
is a critical factor in performance. During a measurement calibration, the temperature of the
calibration devices must be stable and within the range shown in Table 2-1.

Mechanical Characteristics
Mechanical characteristics such as center conductor protrusion and pin depth are not performance
specifications. They are, however, important supplemental characteristics related to electrical
performance. Keysight Technologies verifies the mechanical characteristics of the devices in the kit
with special gaging processes and electrical testing.
This ensures that the device connectors do not exhibit any center conductor protrusion or improper
pin depth when the kit leaves the factory.
“Gaging Connectors” on page 32 explains how to use gages to determine if the kit devices have
maintained their mechanical integrity. Refer to Table 2-2 for typical and observed pin depth limits.
Pin depth
Pin depth is the distance the center conductor mating plane differs from being flush with the outer
conductor mating plane. See Figure 2-1. The pin depth of a connector can be in one of two states:
either protruding or recessed.
Protrusion is the condition in which the center conductor extends beyond the outer conductor
mating plane. This condition will indicate a positive value on the connector gage.
Recession is the condition in which the center conductor is set back from the outer conductor
mating plane. This condition will indicate a negative value on the connector gage.
Figure 2-1 Connector pin depth
The pin depth value of each calibration device in the kit is not specified, but is an important
mechanical parameter. The electrical performance of the device depends, to some extent, on its
pin depth. The electrical specifications for each device in the kit take into account the effect of pin
depth on the device’s performance. Table 2-2 lists the typical pin depths and measurement
uncertainties, and provides observed pin depth limits for the devices in the kit. If the pin depth of a
device does not measure within the observed pin depth limits, it may be an indication that the
device fails to meet electrical specifications. Refer to Figure 2-1 for a visual representation of
proper pin depth (slightly recessed).

When measuring pin depth, the measured value (resultant average of three or more
measurements) is not the true value. Always compare the measured value with the observed pin
depth limits in Table 2-2 to evaluate the condition of device connectors.
Table 2-2 Pin depth limits
Device Typical pin depth Measurement uncertainty[a]
[a] Approximately +2 sigma to -2 sigma of gage uncertainty based on studies done at the factory according to recommended procedures.
Observed pin depth limits[b]
[b] Observed pin depth limits are the range of observation limits seen on the gage reading due to measurement uncertainty. The depth could
still be within specifications.
