Installation

Introduction This chapter explains how to install the HP 8511A test set. The topics

covered include initial inspection, environmental considerations, positioning
and connecting the test set for use, and packaging the instrument. Refer to
the “Installation” chapter of the HP 8510 On-Site Service manual for more
complete system connection and turn-on instructions.

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 3-1.

In addition,check the test setmechanicallyand electrically. If thetestset and
shipping container are undamaged, passing the Operator’s Check (in
Chapter 4, “Operation”) should suffice for incoming inspection. If the test
set does not pass the Operator’s Check, refer to the troubleshooting
procedures in the HP 8510 On-Site Service Manual or call your local HP
Customer Engineer.

If the shipping container is damaged or defective, keep the shipping
materials and notify both the carrier and the nearest Hewlett-Packar d office.
The HP office will arrange for repair orreplacement of the test set without
waiting for settlement of the claim. If the components receivedwith the test
set are incomplete, notify your nearest HP office and the deficient parts will
be sent to you.

Environmental Considerations

Environmental Considerations

Operationand Storage To perform within specifications, the HP 8511A should be operated in

temperatures between 0 °Cand+55°C with relative humidity between 5%
and 95% at 40 °C (maximum dry bulb temperature). It may be operated at
altitudes up to 4,500 metres (15,000 feet).

The HP 8511A may be stored in temperatures from
relative humidity up to 90% at +65 °C (maximum dr y bulb temperature) and
at altitudes up to 15,240 metres (50,000 feet).

Preparation for Use P ositioning the Test Set

Typically the HP 8511A is placed under the HP 8510 network analyzer or
the source whether it is rack-mounted or used on a bench. To install the
flanges to rack mount the instrument (with or without handles) ina standard
19 inch rack, refer to Figure 3-2 on page 3-3.

Static-free
Workstation

When installing the test set for use on a bench, place it on a grounded
anti-static work surface to lessen the chance of ESD damage. The anti-static
surface should extend far enough in front of the test set to provide effective
protection at the test ports and cable ends. If your test set is equipped with a
grounding receptacle, you may use that in place of a static mat.

Controlling Multiple Test Sets

Controlling Multiple Test Sets

Option 001 for the HP 851X-series test sets allows an HP 8510 to alternately
control up to four test sets. While a measurement is proceeding on test set
number 1, which is equipped with option 001, test device hookup can be
accomplished on Test Set number 2,which does not need to be equipped
with option 001, unless another test set is to be connected. When the
measurement on test set number 1 is complete, then the HP 8510 can control
test set number 2.

In a s tandard test set, the 20 MHz IF and control signals are applied directly
to J11 TEST SET INTERCONNECT, which connects to the HP 8510.
Option 001 adds a set of IF switches, control swit ches, and the JIO TEST
SET INTERCONNECT connector. This allows the selectionof 20 MHz test
set IF signals. As shown in Figure 4-5 on page 4-7, test set number l can
apply its IF to the HP 8510 or it can switch to pass the IF from test set
number 2 through the J10 TEST SET INTERCONNECT to the HP 8510.

Initialization at
Power-up

Upon power-up, the IF switches must be configured so t hat only one system

active.

1. Check th e active lights of all syst em te st sets.

2. Check the HP 8510’s expected test set address by pres sing

SET]

. This should match the address of the desired tes tset. If not, change

the address.

3. If unselected test setsare active, (active light ON), deactivate the test set
by temporarily addressing it. Then return to the desired address.

[LOCAL] [TEST

Selecting a Test Set TestSet IF Switching. The activetest set is selectedby the built-in

capability of the HP 8510 to generate an addressed command to the test set.
Each time the HP 8510 ADDRESS of TEST SET function is changed (see
HP 8510 LOCAL Menu), the HP 8510 switches the pr eviously addressed
test set IF to external and the newly addressed test set IF to internal. The test
set front panel ACTIVE indicatorshows the test set status. When the test set
is activethe IF signals from the test set are applied directly to J11 TEST SET
INTER CONNE CT. When the test set is inactive the IF signals appearing at
J10 are passed through to J 11and on to the next test set or the HP 8510.

The address of the test set can be changed manually from the HP8510 front
panel by selecting the ADDRESS of TEST SET function then e nt ering the

[XI],

address of the test set and pressing
control using the HP 8510 GPIB ADDRESS; command. The GPIB address
of a particular test s etis set by a ddre ss switches on the test set rear panel.

RF Switch Driver Commands. A related feature of the HP 8510 is that
when the HP 8510 ADDRESS of TEST SET function is changed, a code
sequence is automatically issued over the HP 8510 system bus to the de vice
at the ADDRESS of RF SWITCH. In the recommended configuration, this
device is an HP 11713A attenuator/switch driver which in turn controls one
or more HP 33311C coaxial switch. As shown in Figure 4-5 on page 4-7 and
Figure 4-6 on page 4-10, these switches are used to select which of the test
sets receive the RF Output of the network analyzer s ource. The exact
command issued depends upon the new value of the ADDRESS of TEST
SET function, also shown in Figur e 4-5 on page 4-7 and Figure 4-6 on
page 4-10.

Calib r ation

After selecting the active test set, perform the system calibration procedure
as usual.When you select a dif f erent test set , make sure that you recallthe
cal set thatapplies to that tes t set .

Since the cal set limited instrument s tate does not include the number of the
act i vetest set, a cal set which does not applyto the current tes t set can be
turned on without any HP 8510 caution messages appearing. This w ill cause
errors inthe displayed data because incorrect errorcoefficients are applied to
the measured data.

It may be conve nient to store a hardwa re state file and an instrument state
file for each combination of test set and cal set. Y ou may also store your
hardware sate file on a disk for future us e. T o change the configuration,
