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:
— Conductive table-mat and wrist-strap combination.
— 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 megohm of isolation from
ground.
Figure 1 Example of a Static-Safe Workstation
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.
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 N9042-90011
Option ST1 and ST2 – IQ Streaming
— 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.

Upgrade Contents
This upgrade kits includes enough parts so that all versions of the N9042B instrument can be
successfully upgraded with the IQ streaming option. Because of that, there may be some parts that
will not be needed. The main differentiator for this is the presence of option G2H in the instrument.
Instruments with option G2H are the latest version of hardware and will not require parts such as
the new rear panel and some of the other small metal parts. The upgrade instructions will call out
option G2H instruments when a decision on what parts to install needs to be made.

Initial Instrument Functionality Check
Power on the instrument and allow it to complete its boot up process. Verify that there are no
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 Software Revision Check
While the instrument is still powered on check to see what version of the instrument software is
installed. To do so press System, Show System and look on the System Information screen for the
Instrument S/W Revision. Record the software revision below.
Instrument S/W Revision Installed: __________

Instrument Configuration Determination
The following instrument condition and configuration checks need to be performed before any work
on upgrading the instrument is done. This information will assist in knowing what needs to be done
to the instrument and what parts will be needed.
Option G2H Check
While the instrument is still powered on check to see if the instrument has option G2H installed. To
do so press System, Show System and look on the System Information screen for option G2H.
Note whether option G2H is installed or not below.
Option G2H Installed: __________ Yes _________ No
Option R40 Check
While the instrument is still powered on check to see if the instrument has option R40 installed. To
do so press System, Show System and look on the System Information screen for option R40. Note
whether option R40 is installed or not below.
Option R40 Installed: __________ Yes _________ No
Installed Power Supply Check
Looking at the writing on the rear panel of the instrument for the power supply maximum power
rating. It will either be 850 W Max or 900 W Max. Enter the value found below.
Maximum Power Rating: __________ Watts Max
Determine Instrument Configuration
If the Maximum Power Rating is 850 watts, the instrument has Configuration A.
If the Maximum Power Rating is 900 watts and the instrument does not have Option G2H, the
instrument has Configuration B.
If the Maximum Power Rating is 900 watts and the instrument has Option G2H, the instrument
has Configuration C.
The instrument configuration determined above will be used when it comes to reinstalling the
instrument rear panel and the associated the rear panel ODI connector.
