Safety Notices
The following safety precautions should be
observed before using this product and any
associated instrumentation.
This product is intended for use by qualified
personnel who recognize shock hazards and
are familiar with the safety precautions
required to avoid possible injury. Read and fol-
low all installation, operation, and main-
tenance information carefully before using the
product.
ARNING
If this product is not used as specified, the
protection provided by the equipment could
be impaired. This product must be used in a
normal condition (in which all means for pro-
tection are intact) only.
The types of product users are:
nResponsible body is the individual or
group responsible for the use and
maintenance of equipment, for ensur-
ing that the equipment is operated
within its specifications and oper-
ating limits, and for ensuring oper-
ators are adequately trained.
nOperators use the product for its
intended function. They must be
trained in electrical safety pro-
cedures and proper use of the instru-
ment. They must be protected from
electric shock and contact with haz-
ardous live circuits.
nMaintenance personnel perform
routine procedures on the product to

keep it operating properly (for
example, setting the line voltage or
replacing consumable materials).
Maintenance procedures are
described in the user documentation.
The procedures explicitly state if the
operator may perform them. Other-
wise, they should be performed only
by service personnel.
nService personnel are trained to
work on live circuits, perform safe
installations, and repair products.
Only properly trained service per-
sonnel may perform installation and
service procedures.
ARNING
Operator is responsible to maintain safe
operating conditions. To ensure safe oper-
ating conditions, modules should not be
operated beyond the full temperature range
specified in the Environmental and physical
specification. Exceeding safe operating con-
ditions can result in shorter lifespans,
improper module performance and user
safety issues. When the modules are in use
and operation within the specified full tem-
perature range is not maintained, module
surface temperatures may exceed safe hand-
ling conditions which can cause discomfort
or burns if touched. In the event of a module
exceeding the full temperature range,
always allow the module to cool before
touching or removing modules from chassis.
Keysight products are designed for use with
electrical signals that are rated Meas-
urement Category I and Measurement Cat-
egory II, as described in the International
Electrotechnical Commission (IEC) Standard
IEC 60664. Most measurement, control,
and data I/O signals are Measurement Cat-
egory I and must not be directly connected
to mains voltage or to voltage sources with
high transient over-voltages. Measurement
Category II connections require protection
for high transient over-voltages often asso-
ciated with local AC mains connections.
Assume all measurement, control, and data
I/O connections are for connection to Cat-
egory I sources unless otherwise marked or
described in the user documentation.
Exercise extreme caution when a shock hazard
is present. Lethal voltage may be present on
cable connector jacks or test fixtures. The
American National Standards Institute (ANSI)
states that a shock hazard exists when voltage
levels greater than 30V RMS, 42.4V peak, or
60VDC are present. A good safety practice is to
expect that hazardous voltage is present in any
unknown circuit before measuring.
Operators of this product must be protected
from electric shock at all times. The respons-
ible body must ensure that operators are pre-
vented access and/or insulated from every
connection point. In some cases, connections
must be exposed to potential human contact.
Product operators in these circumstances
must be trained to protect themselves from
the risk of electric shock. If the circuit is cap-
able of operating at or above 1000V, no con-
ductive part of the circuit may be exposed.
Do not connect switching cards directly to
unlimited power circuits. They are intended to
be used with impedance-limited sources.
NEVER connect switching cards directly to AC
mains. When connecting sources to switching
cards, install protective devices to limit fault
current and voltage to the card.
Before operating an instrument, ensure that
the line cord is connected to a properly-groun-
ded power receptacle. Inspect the connecting
cables, test leads, and jumpers for possible
wear, cracks, or breaks before each use.
When installing equipment where access to
the main power cord is restricted, such as rack
mounting, a separate main input power dis-
connect device must be provided in close prox-
imity to the equipment and within easy reach
of the operator.
For maximum safety, do not touch the
product, test cables, or any other instruments
while power is applied to the circuit under
test. ALWAYS remove power from the entire
test system and discharge any capacitors
before: connecting or disconnecting cables or
jumpers, installing or removing switching
cards, or making internal changes, such as
installing or removing jumpers.
Do not touch any object that could provide a
current path to the common side of the circuit
under test or power line (earth) ground.
Always make measurements with dry hands
while standing on a dry, insulated surface cap-
able of withstanding the voltage being meas-
ured.
The instrument and accessories must be used
in accordance with its specifications and oper-
ating instructions, or the safety of the equip-
ment may be impaired.
Do not exceed the maximum signal levels of
the instruments and accessories, as defined in
the specifications and operating information,
and as shown on the instrument or test fixture
panels, or switching card.
When fuses are used in a product, replace with
the same type and rating for continued pro-
tection against fire hazard.
Chassis connections must only be used as
shield connections for measuring circuits, NOT
as safety earth ground connections.
If you are using a test fixture, keep the lid
closed while power is applied to the device
under test. Safe operation requires the use of a
lid interlock.
ACAUTION notice denotes a hazard. It calls
attention to an operating procedure, practice,

or the like that, if not correctly performed or
adhered to, could result in damage to the
product or loss of important data. Do not pro-
ceed beyond a CAUTION notice until the indic-
ated conditions are fully understood and met.
A WARNING notice denotes a hazard. It
calls attention to an operating procedure,
practice, or the like that, if not correctly per-
formed or adhered to, could result in per-
sonal injury or death. Do not proceed beyond
a WARNING notice until the indicated con-
ditions are fully understood and met.
Instrumentation and accessories shall not be
connected to humans.
Before performing any maintenance, dis-
connect the line cord and all test cables.
To maintain protection from electric shock and
fire, replacement components in mains circuits
– including the power transformer, test leads,
and input jacks – must be purchased from Key-
sight. Standard fuses with applicable national
safety approvals may be used if the rating and
type are the same. Other components that are
not safety-related may be purchased from
other suppliers as long as they are equivalent
to the original component (note that selected
parts should be purchased only through Key-
sight to maintain accuracy and functionality of
the product). If you are unsure about the
applicability of a replacement component, call
an Keysight office for information.
No operator serviceable parts inside. Refer
servicing to qualified personnel. To prevent
electrical shock do not remove covers. For
continued protection against fire hazard,
replace fuse with same type and rating.

Step 1: Unpack and Inspect the Module
Step 1: Unpack and Inspect the Module
The module is shipped in materials which prevent damage from static. The module should only be removed
from the packaging in an anti-static area ensuring that correct anti-static precautions are taken. Store all mod-
ules in anti-static envelopes when not in use.
ESD
Electrostatic discharge (ESD) can damage or destroy elec-
tronic components. Use a static-safe work station to per-
form all work on electronic assemblies. The figure (left)
shows a static-safe work station using two types of ESD pro-
tection: conductive table-mat and wrist-strap combination,
and conductive floor-mat and heel-strap combination. Both
types, when used together, provide a significant level of ESD
protection. Of the two, only the table-mat and wrist-strap
combination provides adequate ESD protection when used
alone. To ensure user safety, the static-safe accessories
must provide at least 1MΩof isolation from ground.
DONOT use these techniques for a static-safe work station when working on circuitry with a voltage potential
greater than 500 volts.
Inspect for Damage
After unpacking a module, inspect it for any shipping damage. Report any damage to the shipping agent
immediately, as such damage is not covered by the warranty (see warranty information at beginning of this
document).
To avoid damage when handling a module, do not touch exposed connector pins.
See www.keysight.com/find/tips for information on preventing damage to your keysight equipment.

abilities. Before installing or removing a module to/from the chassis, power off the chassis to prevent damage
to the module.
This module can be used in a chassis with PXIe or PXI-H chassis slots.
Recommended best practices to ensure proper and safe module operating
conditions
lEnsure proper chassis air flow is maintained
lSelect a chassis that provides thermal protection if fans become inoperable or forced air cooling is
obstructed
lUse slot blockers (Keysight model Y1212A, 5 per kit) and EMC filler panels in empty module slots to
ensure proper operating temperatures. Keysight chassis Keysight M9018A chassis and slot blockers
optimize module temperature performance and reliability of test.
lSet chassis fans to high or auto. Do not disable fans.
Keysight M9300A PXIe Frequency Reference Startup Guide 17

Step 4: Install the Module
lPosition chassis to allow plenty of space around chassis air intake and fan exhaust.
lAt environment temperatures above 45 °C, set chassis fan speed to high.
M9018A Chassis Air Flow
The M9018A has multiple air intakes. They are located at the lower sides, lower front, and bottom of the
chassis.
Module Installation Process Overview
Themodulecanbeinstalled in anyPXIeor hybridPXIslot markedwithaperipheralslot compatibility
image(solidblackcirclefor PXIe,or solidblackcirclewiththeletter “H” for hybrid).
1. Make sure that the line cord is plugged in to establish earth ground and that the chassis power switch is Off.
2. If the chassis has multiple fan speed settings, ensure that the fan switch is set to AUTO and the inhibit switch is set to
DEF.
3. Position the chassis to provide ample space between the chassis fan intake and exhaust vents. Blockage by walls or
obstructions affects the air flow needed for cooling. (Refer to the chassis documentation for more information about
cooling).
4. Before inserting a module into the chassis, back the mounting screws out to ensure that there is no interference
between the screws and the mounting rails.
5. See "M9300A Modular Instrument Connections" on page 20 for positioning the M9300A module as a component of the
Keysight M9380A PXIe CW Source or the Keysight M9381A PXIe Vector Signal Generator. Install the left-most module
18 Keysight M9300A PXIe Frequency Reference Startup Guide

Step 4: Install the Module
first and then proceed installing modules from left to right. If only the M9300A is to be installed, any PXIe or PXI-H slot
may be used.
6. Holding the module by the injector/ejector handle, slide it into an available PXI (or hybrid) slot, as shown in the following
figure.
a. Install the module into the slot of the
chassis by placing the module card edges
into the front module guides (top and bot-
tom).
b. Slide the module to the rear of the chassis
and ensure that the injector/ejector handle
is pushed down in the unlatched (down-
ward) position.
c. Slide the module completely into the
chassis. When you begin to feel resistance,
pull up on the injector/ejector handle to
fully inject the module into the chassis.
7. Secure all modules to the chassis using the module mounting screws. Use a #1 Pozidriv® or a slotted screwdriver and
torque to 5 Lb-In (0.57 N-m). Performance may suffer if the screws are not tightened properly.
8. Verify that the PXI chassis fans are operable and free of dust and other contaminants that may restrict airflow.
9. Install filler panels and slot blockers after installing the modules. Missing filler panels or slot blockers may disrupt air cir-
culation in the chassis. The left-most slot does not accept a slot blocker.
10. Use the Cabling Diagram on the next page to attach the cables to the instrument. The torque specification for SMA con-
nectors is 8 Lb-In (0.904 Nm).
11. Power up the PXI chassis.
12. If you are using a remote PC, reboot the PC host.
13. Proceed to Step 5: Verify Operation of the M9300A Module (Optional) (page 26).
