About this Manual
We’ve added this manual to the Agilent website in an effort to help you support
your product. This manual is the best copy we could find; it may be incomplete
or contain dated information. If we find a more recent copy in the future, we will
add it to the Agilent website.
Support for Your Product
Agilent no longer sells or supports this product. Our service centers may be able
to perform calibration if no repair parts are needed, but no other support from
Agilent is available. You will find any other available product information on the
Agilent Test & Measurement website, www.tm.agilent.com.
HP References in this Manual
This manual may contain references to HP or Hewlett-Packard. Please note that
Hewlett-Packard's former test and measurement, semiconductor products and
chemical analysis businesses are now part of Agilent Technologies. We have
made no changes to this manual copy. In other documentation, to reduce
potential confusion, the only change to product numbers and names has been in
the company name prefix: where a product number/name was HP XXXX the
current name/number is now Agilent XXXX. For example, model number
HP8648A is now model number Agilent 8648A.

General Safety Considerations
WARNING
No operator serviceable parts inside. Refer servicing to
qualied personnel. To prevent electrical shock, do not remove
covers.
If this instrument is not used as specied, the protection
provided by the equipment may be impaired. This instrument
must be used in a normal condition (in which all means for
protection are intact) only.
For continued protection against re hazard, replace line fuse
only with same type and rating ([F 5A/250V]). The use of other
fuses or material is prohibited.
CAUTION
Before switching on this instrument, make sure that the line voltage
selector switch is set to the voltage of the power supply and the
correct fuse is installed.
Always use the three-prong ac power cord supplied with this
instrument. Failure to ensure adequate earth grounding by not
using this cord may cause instrument damage.
Only clean the instrument cabinet using adamp cloth.

Preparing for Use
Introducing the EMI Receiver
The EMI receiver includes the receiver RF section, the RF lter
section, and all the accessories you will need to prepare the system
for use.
This chapter contains information about accessories supplied, initial
inspection, electrostatic discharge, and available power cables.
In addition, installation procedures show how to install the handles,
lock the system together, set the line voltage selector switches, check
the fuses, add the front and rear cables, and set the HP-IB address.

Initial Inspection
Inspect the shipping container for damage
. If the shipping container
or cushioning material is damaged, keep it until you have veried
that the contents are complete and you have tested the EMI receiver
mechanically and electrically.
Table 1-1 contains the accessories shipped with the EMI receiver.
If the contents are incomplete or if the EMI receiver does not pass
the operation verication tests in Chapter 2, notify the nearest
Hewlett-Packard oce. If the shipping container is damaged or the
cushioning material shows signs of stress, also notify the carrier. Keep
the shipping materials for the carrier's inspection. The HP oce
will arrange for repair or replacement without waiting for a claim
settlement.
If the shipping materials are in good condition, retain them for
possible future use.You may wish to ship the EMI receiver to another
location or return it to Hewlett-Packard for service. See \Returning
the EMI Receiver for Service," in Chapter 3, for more information
about shipping materials.
1-4 Preparing for Use

Electrostatic Discharge
Electrostatic discharge (ESD) can damage or destroy electronic
components
.All work on electronic assemblies should be performed
at astatic-safe work station. Figure 1-2 shows an example of a
static-safe work station using two types of ESD protection:
Conductive table-mat and wrist-strap combination.
Conductive oor-mat and heel-strap combination.
Both types, when used together, provide a signicant 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 M of isolation from ground. Refer to Table 1-2 for information on
ordering static-safe accessories.
WARNING
Do not use either of the two types of ESD protection described
above for a static-safe work station when working on circuitry
with avoltage potential greater than 500 volts
.
Figure 1-2. Example of a Static-Safe Work Station
Preparing for Use 1-5

Reducing Damage Caused by ESD
The following suggestions may help reduce ESD damage that occurs
during testing and servicing operations.
Before connecting any coaxial cable to an EMI receiver connector
for the rst time each day, momentarily ground the center and
outer conductors of the cable.
P
ersonnel should be grounded with a resistor-isolated wrist strap
before touching the center pin of any connector and before
removing any assembly from the unit.
Be sure that all instruments are properly earth-grounded to prevent
abuildup of static charge
.

1-6 Preparing for Use

Installation Procedures
This section provides procedures on how to prepare the EMI receiver
and receiver RF section for use. Refer to the procedure below that
applies to your instrument.
Installing the EMI receiver
Installing the receiver RF section
WARNING
Do not lift the instrument by its handles when it is congured as
an EMI receiver
,that is
, when the receiver RF section is joined
together with the RF lter section. Otherwise, personal injury
may be incurred.
CAUTION
V
entilation Requirements:
When installing the instrument in a
cabinet, the convection into and out of the instrument must not be
restricted. The ambient temperature (outside the cabinet) must be
less than the maximum operating temperature of the instrument
by 4

C for every 100 watts dissipated in the cabinet. If the total
power dissipated in the cabinet is greater than 800 watts, then forced
convection must be used.
CA
UTION
The EMI receiver and receiver RF section are designed for use in
Installation Category II and Pollution Degree 2 per IEC 1010 and 664,
respectively
.
