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 oce. 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 oce
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 a static-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 a voltage 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.
Personnel 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
a buildup of static charge.
Table 1-2 lists static-safe accessories that can be obtained from
Hewlett-Packard by using the HP part numbers shown.

Operation Veri cation
This chapter contains operation veri cation test procedures that test
the electrical performance of the receiver.
Allow the receiver to warm up in accordance with the Temperature
Stability speci cation before performing the tests in this chapter.
None of the test procedures involve removing the cover of the
receiver.
Operation veri cation tests only the most critical speci cations of
the receiver. These tests are recommended for incoming inspection,
troubleshooting, or after repair.

Read the rest of this section before you start any of the tests, and
make a copy of the Operation Veri cation Test Record at the end of
this chapter.
2-2 Operation Veri cation
Test equipment you will need
Tables 2-2 through 2-4 list the recommended test equipment,
accessories, and cables for the manual operation veri cation. Any
equipment that meets the critical speci cations given in the table can
be substituted for the recommended model.
Recording the test results
A operation veri cation test record is provided at the end of this
chapter.
Each test result is identi ed as a TR Entry in the operation
veri cation tests and on the operation veri cation test record. We
recommend that you make a copy of the operation veri cation test
record, record the test results on the copy, and keep the copy for your
test record. This record could prove valuable in tracking gradual
changes in test results over long periods of time.
If the receiver doesn't meet speci cations
If the receiver fails one or more speci cations, complete any
remaining tests and record all test results on a copy of the operation
veri cation test record. Then refer to Chapter 3, \Customer Support,"
for instructions on how to solve the problem.
Periodically verifying operation
The receiver requires periodic veri cation of operation. Under most
conditions of use, you should test the receiver at least once a year
with either operation veri cation or the complete set of operation
veri cation tests.
