Connector Kit Overview

The N9041B, Signal Analyzer has two input connectors, the right side RF Input 1
connector is a 2.4 mm male.

The left side RF Input 2 connector is a special 1.0 mm male Keysight bulk head
connector that has 14 mm wrench flats. This test port connector has external
threads that accept the Keysight Test port adaptors, and has internal threads that
will accept Keysight standard 1.0 mm female adaptor, such as the 11920B.

The Connector Kit contains:

Adaptor - 2.4 Female to K Female Used on RF Input 1 as a connector saver to

connect 3.5 mm or sma devices or cables.

Use of the Test Port Adaptors on Instrument RF Input 2

Use of the Test Port Adaptors on Instrument RF Input 2

Two, 1mm test port adaptors are supplied in the kit. The 1 mm female test port to
1 mm female adaptor is used as a connector saver to extend the lifespan of the
instrument RF Input 2 connector. The other test port adaptor is a 1mm female test
port to 1.85 mm female adaptor. This adaptor is also a connector saver.

USE CAUTION WHEN INSTALLING ADAPTORS! Rotation of the adaptor after the
connectors are engaged will damage the input connector on the instrument.

1. Align the test port adaptor with the 1 mm RF Input 2 connector on the instrument
and engage the nut of the input connector with the adaptor. Fully engage the
threads, but do not attempt to fully torque the connection.

2. Locate the torque wrench in the kit.
a. If connecting the 1 mm to 1 mm adapter, locate a 12 mm open end wrench.

b.

If connecting the 1 mm to 1.85 mm adapter, locate a 8 mm open end wrench.

3. Place the jaws of the open end wrench onto the test port adaptor wrench flats,
but do not turn this wrench.

4. Place the jaws of the 10-inch-pounds end of the torque wrench onto the
instrument RF Input 2 connector. While holding the test port adaptor still with
the open end wrench, torque the input connector to 10- inch-pounds.

Input Connector Vise Assembly

Input Connector Vise Assembly

Keysight Technologies recommends the use of the supplied Keysight Technologies
test port adaptors when using RF Input 2, the 1 mm input connector. The test port
adaptors attach to the external threads on the instrument bulkhead input connector.

However, if Keysight Technologies standard adaptors will be used instead of the test
port adaptors, the use of the supplied Connector Vise assembly is recommended to
prevent damage to the 1 mm input connector due to over torque.

Standard adaptors other that those manufactured by Keysight Technologies may
not work with the Vise Clamp.

USE CAUTION WHEN INSTALLING ADAPTORS! Rotation of the adaptor after the
connectors are engaged will damage the input connector on the instrument.

To use Keysight Technologies standard adaptors with the Vise Clamp:

1. Install the Vise Clamp with the two supplied pan-head screws. Tighten the
screws to 9 inch-pounds.

2. Loosen the Vise Clamp screw so that the vise jaws clear the body of the standard
adaptor that is to be used.

3. Align the flats of the 1 mm female end of the adaptor with the vise jaws and
tighten the Vise Clamp screw until the jaws grip the adaptor. Loosen the screw
slightly to allow the adaptor to slide in the jaws.

4. Align the adaptor with the 1 mm input connector on the instrument and engage
the nut of the input connector with the adaptor. Fully engage the threads, but do
not attempt to fully torque the connection.

5. Re-align the jaws of the vise so they make good contact with the flats on the
adaptor. Do this by pulling back on the vise jaws while tightening the vise clamp
screw. DO NOT OVER TIGHTEN.

6. Tighten the input connector nut to 4 inch-pounds using the 4-inch-pounds end of
the 14 mm torque wrench.

7. Re-tighten the vise clamp screw to snugly lock the jaws against the flats of the
adaptor. DO NOT OVER TIGHTEN.

8. If the standard adaptor will remain on the input connector for a long period of
time, periodically check the Vise Clamp screw to ensure that it remains snugly
tightened.

Input Connector Vise Assembly

The Vise Clamp will now protect the input connector from damage when
connections are made to the adaptor that exceed 4 inch-pounds torque. The Vise
Clamp is only a rotation prevention device. It will not protect the input connector
against damage from bending due to heavy side to side or up/down loading on the
adaptor.

RF Input 1, 2.4 mm adaptor installation

Align the adaptor with the 2.4 mm input connector on the instrument and engage the
nut of the input connector with the adaptor.

Torque the bulkhead 2.4 mm input connector (with an 8 mm or 5/16" torque wrench)
to 8 inch-pounds while holding the adaptor with a 7 mm open-end wrench.

Visual Inspection

Visual Inspection

Visual inspection and , if necessary cleaning should be done every time a connection
is made. Metal particles from connector threads may fall into the connector when it
is disconnected. One connection made with a dirty or damaged connector can
damage both connectors beyond repair.

Magnification is helpful when inspecting connectors, but it is not required and may
actually be misleading. Defects and damage that cannot be seen without
magnification generally have no effect on electrical or mechanical performance.
Magnification is of great use in analyzing the nature and cause of damage and in
cleaning connectors, but it is not required for inspection.

Obvious defects or damage

Examine the connectors first for obvious defects or damage:

– Plating

– Bare metal showing

– Burrs or blisters

– Deformed threads

– Center conductors

– Bent

– Broken

– Misaligned

– Concentricity

– Connector nuts should move smoothly and be free of:

– Burrs

– Loose metal particles

– Rough spots

Any connector that has obvious defects should be discarded.

Connector Contacts

Inspect the connector contacts for integrity. It is necessary to use good lighting (such
as a halogen task light) to see the contacts.

Notice the location of the cross hairs in relationship to the center of the figures.

Contact integrity

Refer to the following for visual guidelines when evaluating the contact integrity of a
connector.

Making Connections

Good connections require a skilled operator. Instrument sensitivity and coaxial
connector mechanical tolerances are such that slight errors in operator technique
can have a significant effect on measurements and measurement uncertainties.

The most common cause of measurement error is poor connections.

Connection Procedure

1. Ground yourself and all devices (wear a grounded wrist strap and work on an
antistatic mat).

2. Visually inspect the connectors (refer to Visual Inspection).

3. If necessary, clean the connectors (refer to Cleaning Connectors).

4. Carefully align the connectors. The male connector center pin must slip
concentrically into the contact fingers of the female connector.

2 Connector Care

Making Connections

5. Push the connectors straight together. Do not twist or screw them together. As
the center conductors mate, there is usually a slight resistance.

6. Do not twist one connector into the other (like insertinga light

bulb). This happens when you turn the device body, rather than the
connector nut. Major damage to the center conductor and the outer
conductor can occur if the device body is twisted.

7. Initial tightening can be done by hand or with an open-end wrench. Tighten until
"snug" or where the connectors are first making contact. The preliminary
connection is tight enough when the mating plane surfaces make uniform, light
contact. Do not over tighten this connection.
At this point, all you want is for the outer conductors to make gentle contact on
both mating surfaces. Use very light finger pressure (no more than 2 inch-pounds
of torque).

8. Relieve any side pressure on the connection from long or heavy devices or
cables. This assures consistent torque.

9. Torque the cable or device to the final value using a torque wrench.

Cleaning Connectors

Cleaning Connectors

Basic Cleaning Procedure

1. Inspect the connectors for dust, dirt, metal fragment, oils or film, and debris.

2. Blow off any dust with a filtered, clean supply of compressed air.

3. Add a few drops of high-purity isopropyl alcohol to a small cleaning swab (do not
apply alcohol directly to the parts).

4. When using isopropyl alcohol to clean connectors do not allow the

liquid to flow down inside the connector. This may cause
measurement errors due to residue inside the connector. If possible
keep the connector facing down.

5. Gently wipe connecting surfaces with the end of the cleaning swab.

6. Blow dry with compressed air.

7. Inspect and repeat cleaning procedure if necessary.
