OPERATING AND SAFETY PRECAUTIONS


Operating

You need observe only normal precautions in handling and operating the 87511A/B. Do not
exceed its operating level input of +23 dBm or any DC voltage.
Caution        Electrostatic discharge (ESD) can damage the highly sensitive microcircuits
               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 a path to ground of high resistance. Alternatively, ground
               yourself by touching the outer shell of any grounded instrument chassis before
               touching the test port 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 warrant more than normal caution for operator safety.
Nevertheless, service should be performed by qualied personnel.

Installation
INTRODUCTION

This chapter explains how to 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
suce for incoming inspection. If the test set does not pass the performance test, refer to the
troubleshooting procedures 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 both the carrier and the nearest Agilent Technologies oce. The Agilent
Technologies oce will arrange for repair or replacement of the test set without waiting for
settlement of the claim.

ENVIRONMENTAL CONSIDERATIONS


Operating and Storage

The 87511A/B should be operated in temperatures between 0 C and +55 C with relative
humidity between 5% and 95% at 40C (non-condensing). It may be operated at altitudes up
to 4,500 meters (15,000) feet.
The 87511A/B may be stored in temperatures from 040 C to +70 C, with relative humidity
up to 90% at +65 C (non-condensing) and at altitudes up to 15,240 meters (50,000 feet).


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 bench, place it under or next to the 8751A. Use an
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
 type-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 ports of the 87511A/B are precision 50
 type-N female connectors
which mate with the corresponding precision type-N male connectors whose dimensions
conform to US speci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.

2-2   Installation
Signal Path Connections

Place the test set under the network analyzer and connect its RF IN port to the network
analyzer's RF OUT port, R to R, A to A, B to B. Use the four cables supplied with the test
set.
To connect the signal path ports with the test set not positioned under the network analyzer,
use the longer cables of the 11851B RF cable set. Connect the RF IN port to the RF OUT
port with the longer cable. Connect port R to R, A to A, B to B with the three phase
matched cables.


PACKAGING

If shipping to a Hewlett Packard service center is required, each test set should be repackaged
using the original factory packaging materials.
Alteratively, comparable packaging materials may be used. Wrap the test set in heavy paper
or anti-static plastic. Use sucient shock absorbing material on all sides of the 87511A/B to
provide a thick, rm cushion and prevent movement. Seal the shipping container securely and
mark it FRAGILE .
In any correspondence with Agilent Technologies, refer to the 87511A/B by its full model and
serial number.

Performance Tests
INTRODUCTION

This chapter provides the test procedures used to verify that the 87511A/B's specications
listed in this manual are met. All tests can be performed without access to the interior of
the instrument. The performance tests can also be used to perform incoming inspection,
and to verify that the 87511A/B meets performance specications after troubleshooting or
adjustment. If the performance tests indicate that the 87511A/B is NOT operating within the
specied limits, check your test setup, and then proceed to Adjustments or Troubleshooting in
the 87511A/B service manual, if necessary.
Note           Perform all performance tests in an ambient temperature of 23  C 6 5  C.




PERFORMANCE TEST RECORD

Record the performance test results in the Test Record at the end of this chapter (Photocopy
the Test Record and use the photocopy). The Test Record lists all test specications and
their acceptable limits. Test results recorded during incoming inspection can be used for
comparison purposes during periodic maintenance, troubleshooting, and after repair or
adjustment.
Note           The test limits indicated for each test do not take into account the
               measurement error of the test equipment used. Be sure to take the test
               equipment's measurement error into account when determining whether or not
               the 87511A/B meets specications.



CALIBRATION CYCLE

The 87511A/B requires periodic performance verication. The frequency of performance
verication depends on the operating and environmental conditions under which the
87511A/B is used. Verify the 87511A/B's performance at least once a year, using the
performance tests described in this chapter.

DIRECTIVITY TEST

Directivity is a measure of the ability of a directive device (in this case the 87511A/B) to
discriminate between incident and re
ected signals. In this procedure directivity is tested
by using the internal bridge to measure the re
ection coecient of a standard termination.
Since the return loss of the termination is much greater than the directivity of the test set, the
measurement made in this procedure is essentially the directivity of the 87511A/B test set.
Use the highest quality termination available as that factor determines the accuracy of the
procedure.

Procedure


Note                By convention, when the connector sex is indicated in parentheses for a
                    calibration standard, it refers to the sex of the test port connector (not
                    the actual standard). For example, short (f) indicates that the test port
                    connector, note the short circuit connector, is female.

 1. Connect the equipment as shown in Figure 4-1.

4-8      Performance Tests
EFFECTIVE SOURCE MATCH TEST

This test checks the source match of the 87511A/B. This procedures determines the eective
source match of port 1 and port 2 by examining the calibration coecient arrays. These
arrays are generated during measurement calibration. The array data are the dierence
between the measured known calibration standards and ideal modeled data. Thus the
calibration coecient arrays are a direct indication of performance because they represent the
systematic errors of the test set.
