ESD Information
Protection from Electrostatic Discharge
Electrostatic discharge (ESD) can damage or destroy electronic components. All work on electronic
assemblies should be performed at a static-safe workstation. Figure 1 shows an example of a
static-safe workstation using two types of ESD protection:
—Conductivetable-matandwrist-strap combination.
—Conductivefloor-matandheel-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 megohm of isolation from
ground.
Figure 1 Example of a Static-Safe Workstation
These techniques for a static-safe workstation should not be used when working on circuitry
with a voltage potential greater than 500 volts.

6Installation Note N9038-90039
Option EXM – External Mixing Upgrade
Handling of Electronic Components and ESD
The possibility of unseen damage caused by ESD is present whenever components are transported,
stored, or used. The risk of ESD damage can be greatly reduced by paying close attention to how all
components are handled.
— Perform work on all components at a static-safe workstation.
— Keep static-generating materials at least one meter away from all components.
— Store or transport components in static-shielding containers.
Test Equipment Usage and ESD
— Before connecting any coaxial cable to an analyzer connector, momentarily short the center and
outer conductors of the cable together.
— Personnel should be grounded with a 1 megohm resistor-isolated wrist-strap before touching
the center pin of any connector and before removing any assembly from the analyzer.
— Be sure that all analyzers are properly earth-grounded to prevent build-up of static charge.
For Additional Information about ESD
For more information about preventing ESD damage, contact the Electrical Over
Stress/Electrostatic Discharge (EOS/ESD) Association, Inc. The ESD standards developed by this
agency are sanctioned by the American National Standards Institute (ANSI).
Always handle printed circuit board assemblies by the edges. This will reduce the possibility of
ESD damage to components and prevent contamination of exposed plating.

Initial Instrument Functionality Check
Power on the instrument and allow it to complete its boot up process, run its initial alignments and
display the initial measurement screen. Verify that there are no alignment failures or other
instrument messages that would indicate that there is an issue with either the instrument hardware
or software. If there are any issues, investigate and fix the problem before continuing with this
upgrade.
Instrument Operating System Requirement Verification
Verify that Option W7X (Windows Embedded Standard 7, 64 bit OS) is installed in the instrument by
pressing System, Show, System and verify that there is an entry for:
N9038A-W7X Windows Embedded Standard 7, 64 bit OS
If N9038A-W7X is not found in the instrument do not proceed any further with this upgrade. Option
N9038AK, N9094AK-PC4 (or greater) and N9094AK-W7X will need to be installed before
proceeding.
Frequency Range Option Determination
The frequency range option an instrument has will need to be known in order to perform this
upgrade. To determine this press System, Show, System and look for the N9038A-5xx option that
is installed and note it in the space below.
Frequency Range Option: N9038A-5___
The frequency range option recorded above will be used to determine certain steps to take in the
installation instructions to follow.
