Step 1: Unpack and Inspect the Modules
The modules are 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.

Inspect for Damage
After unpacking a solution, inspect all components for any shipping damage. Report any damage to the ship-
ping agent immediately, as such damage is not covered by the

Return an Instrument for Service
Should it become necessary to return an instrument for repair or service, follow the steps below:
It is recommended that you return all modules and cables of the M9381A or M9391A instrument for repair and
calibration. If your Keysight M9300A PXIe Frequency Reference is operating properly, you need not send it in
with the other modules because your instrument may be repaired and calibrated without your M9300A. Doing
so, however, will effect your calibration schedule, since repairs are followed by calibration. The Calibration
Due Date for your M9300A will not match the date of your other modules.
All component modules for an M9381A M9391A instrument are factory tested, aligned, calibrated and shipped as
a "bundle". It is important that you maintain the bundle when installing modules or returning an instrument for
repair. See

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 MΩ of isolation from ground.
DO NOT use these techniques for a static-safe work
station when working on circuitry with a voltage potential greater
