Safety Summary
The follo
wing general safety precautions must be observed during all phases of op eration,
service, and repair of this instrument. Failure to comply with these precautions or with
specic
W
ARNINGS giv
en elsewhere in this manual violates safety standards of design,
manufacture, and intended use of the instrument.
The Agilent Technologies assumes no liability for the customer's failur
etocomply with these
requir
ements.
DO NOT Operate In An Explosive Atmosphere
Do not op erate the instrument in the presence of ammable gasses or fumes. Operation of any

OPERATING AND SAFETY PRECAUTIONS
Operating
You need observe only normal precautions in handling and op erating the 87511A/B. Do not
exceed its op erating level input of +23 dBm or any DC voltage.
Caution
Electrostatic discharge (ESD) can damage the highly sensitive micro circuits
in the 87511A/B test sets. ESD damage is most likely to occur as the test
sets are connected or disconnected. Protect them by wearing a grounding
strap that provides apathto ground of high resistance. Alternatively,ground
yourself by touching the outer shell of any grounded instrument chassis before
touching the test p ort connectors.
Never touch the center contacts of the connectors.
Use a work station equipped with an anti-static surface.
Service
The voltages in this test set do not w
arrant more than normal caution for operator safety.
Nevertheless, service should be p erformed b
y qualied p ersonnel.

Installation
INTRODUCTION
This chapter explains ho
wto install the 87511A/B test set. The topics covered include initial
inspection, environment considerations, positioning and connecting the test set for use, and
packaging the instrument.
INITIAL INSPECTION
Inspect the shipping container (including cushioning material) for damage. If it is damaged,
keep it until you have checked the contents for completeness. The contents are listed in
Table 2-1.
In addition, check the test set mechanically and electrically. If the test set and shipping
container are undamaged, performing the Directivity performance test in Chapter 4 should
suce for incoming insp ection. If the test set do es not pass the performance test, refer to the
troublesho oting pro cedures in Chapter 7.
If the shipping container is damaged, perform all electrical performance tests in Chapter 4. If
the test set fails the electrical tests, or is damaged, defective, or incomplete, keep the shipping
materials and notify b oth the carrier and the nearest Agilent Technologies oce. The Agilent
Technologies oce will arrange for repair or replacement of the test set without waiting for
settlementof the claim.

PREPARATION FOR USE
Positioning the Test Set
Typically the 87511A/B is placed under the 8751A network analyzer whether it is
rack-mounted or used on a bench.
To install the 87511A/B for use on a b ench, place it under or next to the 8751A.Usean
anti-static work surface to lessen the chance of ESD damage.
Connecting the Test Set
Mating Connectors
Ports 1 and 2 of the 87511A are precision 7 mm connectors and mate with precision 7
mm connectors. Ports 1 and 2 of the 87511A Option 001 are precision 50 type-N female
connector and mate with precision 50 male connectors. Ports 1 and 2 of the 87511B are
precision 75 typ e-N female connector and mate with precision 75 male connectors.
Caution
Do not mate type-N 50 connectors to type-N 75 connectors or damage may
result.
The RF IN, R, A and B p orts of the 87511A/B are precision 50 t
ype-N female connectors
which mate with the corresp onding precision type-N male connectors whose dimensions
conform to US sp ecication MIL-C-39012.
The NETWORK ANALYZER INTERCONNECT connector is a series D 25-contact female
connector and mates with the corresponding male connector.
Power and Control Connections
Power for the 87511A/B is supplied by the 8751A network analyzer through the interconnect
cable. The interconnect cable also transmits control signals between the test set and the
network analyzer. Connect the interconnect cable from the NETWORK ANALYZER
INTERCONNECT connector on the rear panel of the 87511A/B to the TEST SET
INTERCONNECT connector on the rear panel of the 8751A.
