INSTRUMENTS COVERED BY MANUAL

You will find a two-part serial number on the rear panel of the instrument. The first four digits and the

letter are the serial number prefix. The last five digits are the sequential suffix which is unique to each test set. The contents of this manual apply directly to test sets with the same serial number prefix as the one(s) on the title page under the heading

If the serial prefix of your test set is not listed on the title page, your instrument differs from those documented in this manual. The differences are documented in the yellow manual changes supplement supplied with the manual.

To keep this manual as current and accurate as possible, Hewlett-Packard recommends that you periodically request the latest manual changes supplement, as it may contain replacement information as well as change information. The supplement for this manual is keyed to the manual’s print date and part number (on the title page) and is available on request from Hewlett-Packard.

Serial Numbers.

You can order this manual in microfiche form (the part number appears on the title page). With the manual (in 4 x 6 inch microfilm transparency format) you will also receive the latest manual changes supplement.

DESCRIPTION AND OPERATING CHARACTERISTICS OF THE INSTRUMENT

The combination of the HP 8514B test set with the HP8510 network analyzer and source provides a system for making S-parameter measurements over the frequency range of 45 MHz to 20 system is suited for making measurements on two port devices when it is inconvenient or inexpedient to physically reverse the DUT (device under test) to measure all four S-parameters.

The

HP8514B

uses two couplers for signal separation. For measurements of active devices, the

standard HP 8514B includes:

four RF to IF converters to measure all four S-parameters without reconnecting the DUT,

two 90 dB programmable step attenuators for changing (in 10 dB steps) the incident power

level at both ports,

two bias tees for applying external dc bias to both test port center conductors.

GHz.

This

1-2

General Information

8514B/85l2A

Test Sets

In the “High Forward Dynamic Range Configuration” (option 003) the Port 2 coupler is reversed to optimize dynamic range in the forward measurement direction. Because the b2 sampler is connected to the coupler through path instead of the coupled arm, there is less isolation between the b2 sampler and Port 2, and the b2 power level will be higher than bl. This configuration is better for wide dynamic range or reciprocal devices or components like filters, cables, or antennas, where

S,, is generally not

measured. However, as a result of the lower isolation between the test port and the sampler, “sampler bounce,”

appearing as an occasional spurious response related to the

VT0

frequency, can be

noticeable in this “asymmetrical” test set.

The HP 8512A reflection/transmission test set uses one coupler for signal separation. The standard HP 8512A has:

three RF to IF converters, for making reflection (S,,) and transmission (S,,) measurements,

no step attenuators to internally change the incident power level,

no bias tees to apply external DC bias to the test port center conductors.

Option 001

This option adds IF switching capability to allow up to four test sets to be connected to the HP8510B at the same time. The test set in use is selected from the HP85108 front panel. The 20 MHz IF signal is transmitted from the standard test set through the option 001 test set(s) to the network analyzer. IF switching is performed automatically by the option 001 test set(s), without reconnections.

Option 002 (HP 85148 only)

This option deletes the 90 dB programmable step attenuators and the dc bias tees. Note that bias can be applied externally, using the

HP11612A

bias tee, if bias is required but attenuation not.

Option 003 (HP 85148 only)

This high forward dynamic range configuration is described in detail in this section under the title

Description and Operating Characteristics of the Instrument.

Option 002/003 (HP 85148 only)

This option is a combination of option 002 and option 003, which were previously described.

Static Free Workstation

When installing the test set for use on a bench, place it on a grounded anti-static work surface (Figure 2-3) 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 receptical, you may use that in place of a static mat.

HP 8514B/85E!A Test Sets

Connect the system bus cable from the HP85148 (or 8512A) J12 8510 SYSTEM BUS connector to the 8510 INTERCONNECTconnector of the HP85101 display/processor. The test set IF interconnect cable and the system bus cable transmit control signals between the test set and the network analyzer.

Signal Path Connections.

The IF signals from the test set are transmitted to the HP 85102 IF Detector

by the test set IF interconnect cable (see above). RF signals are transmitted from the source to the test set by the 3.5 mm flexible RF cable supplied with

the test set. Recommended torque is 56 N-cm (5in.-lb) for the RF cable-to-test-set/RF input connection.

Anti-Rotation Clamps.

(HP8514B only) Use these clamps to stabilize the test port/RF cable connec-

tion. Connect the test port cables to the test ports and tighten them as specified in the cable manual. Loosen the anti-rotation clamp thumb screw sufficiently to slip the clamp over the cable and up to the front panel. The clamp end with the flats should come to rest on the flats of the test port shoulder. Finger tighten the thumb screws to prevent further loosening or tightening of the test port/RF cable connection.

The internal O-ring is field replaceable without disassembling the anti-rotation clamp. Pry it out with fine tweezers or a similar tool when it no longer holds the RF cable securely. Insert the new O-ring by engaging one side of it in the slot of the phenolic clamp donut. Use your fingers to push the O-ring into the rest of the slot.

The HP part number of the O-ring is 0900-0007 (CD 7).

PACKAGING

If reshipping is required, each test set should be repackaged in the original factory package. Con-

tainers and materials identical to those used by the factory are available through Hewlett-Packard offices.

Alternatively, comparable packaging materials may be used. Wrap the test set in heavy paper or antistatic plastic. If shipping to an HP Office or Service Center, complete and attach a service tag (in the HP 8510 manual set). Use sufficient shock absorbing material on all sides of the test set to provide a thick, firm cushion and prevent movement. Seal the shipping container securely and mark it

FRAGILE.

In any correspondence with HP, refer to the test set by full model and serial number.

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. Only one HP 8516A test set may be used in a multiple test set configuration.

In a standard test set, the 20 MHz IF and control signals are applied directly to

INTERCONNECT, which connects to the HP 8510. Option 001 adds a set of IF switches, control switches, and the JlO TEST SET INTERCONNECT connector. This allows the selection of 20 MHz test set IF signals. As shown in Figure 3-5, test set number 1 can apply its IF to the HP 8510 or it can switch to pass the IF from test set number 2 through the JlO TEST SET INTERCONNECT to the HP 8510.

After selecting the active test set, perform the system calibration procedure as usual. When you select a different test set, make sure that you recall the Cal Set that applies to

test set.

Since the Cal Set Limited Instrument State does not include the number of the active test set, a Cal Set

which does not apply to the current test set can be turned on without any HP 8510 caution messages

appearing. This will cause errors in the displayed data because incorrect error coefficients are applied

to the measured data.

It may be convenient to store a Hardware State file and an Instrument State file for each combination of test set and cal set. You may also store your Hardware State file on a tape or disc for future use. To change the configuration, simply recall the appropriate Hardware State file, which sets the Address of Test Set and issues the RF switch command, then the appropriate Instrument State file, which recalls the Cal Set.

Cable and Anti-Rotation Clamp Installation

The HP 08515-60003 Anti-Rotation Clamps are used to secure the RF connections at the test ports of several Hewlett-Packard test sets. When installed, each clamp holds the large nut that secures the test set RF port connector to the front panel, and the RF cable connector or the front panel adapter mated with the port connector.

Without the clamps, the test port connections may become loose after moving the connected device

and could invalidate calibrations and measurements.

NOTE:

Although the anti-rotation clamps may be used with front panel adapters, these instructions

refer to an installation using the HP RF Cables. Adapter installations will be similar.

Two anti-rotation clamps are included in the test set accessories box. Remove one from the box and loosen the thumbscrew until it is almost out of the counter-bored hole in the clamp body.

Gently push the clamp (round-hole end first) over and past the RF cable connector you will connect to the test set RF port. The rubber O-ring in the round end of the clamp will fit tightly over the connector. Wiggle the clamp if necessary to get it over the connector.

Connect the cable to the test port and tighten as specified in the cable manual. Make sure that you do not twist the cable as you attach it to the test port. Use the torque wrench supplied with your calibration kit to tighten the cable to no more than 90 N-cm (8 in.-lb.).

Important! The test set RF connector is easily loosened so hold the RF cable throughout the rest of

this procedure. Do not allow the cable to rotate.

See Figure 3-7. Turn the clamp so that the thumbscrew is pointing up. From there, turn the clamp to visually align the clamp flats with the flats on the test port connector nut. This will minimize rotating the connector in the next step.

NOTE:

The flats may be in any orientation in respect to the front panel.

TEST SET TEMPERATURE

The processor on the A4 HP-IB assembly monitors the test set temperature with a comparator on the A3

VT0

summing amplifier. The temperature sensor is located on the Al4 VTO/driver assembly. If the

temperature of the VTO/driver exceeds 85°C the HP 85101 displays the “Test Set Too Hot” prompt.

TEST SET TOO HOT means turn off the test set immediately. This message is only a prompt. It does not turn off the test set.

Determine the reason for the prompt before again subjecting the test set to continuous use. Make sure

the fan is operating properly and is not covered by a piece of paper, etc. Make sure the fan and the side

panel air exhaust has at least 8 cm (about 3 inches) clearance, and top cover exhaust has at least 1.5 cm

(about 0.5 inches) clearance.

CHECK ALL CONNECTIONS (loose, broken, crimped, etc.)

Power holes (power loss at a specific frequency) often result from faulty connections. Check the

following connections:

Test set rear panel (including the extension links)

Cables connected to the A3 summing amplifier and A5 Attenuator/Switch

Sampler cables

RF path connections from rear panel to front panel

CHECK POWER SUPPLY/REGULATOR, FUSES, AND SWITCHES

TEST SET SELF-TEST INDICATORS

If the ACTIVE LED on the front panel does not light within two seconds of turn on, or lights immediately, the test set has not passed its self-test. You can determine what part of the self-test failed by determining which HP-IB LEDs on the A4 assembly are lit. The table below shows the possible self-test failures:

Two seconds after turn-on all four HP-IB LEDs should go off, and the front panel ACTIVE LED should

light simultaneously. After going out briefly, the HP-IB LEDs will light according to the state of the test set. If you are using multiple test sets, the first test set in line will be the active test set until another is

chosen.

The configuration switch is on the A3 summing amplifier assembly (see Figure 5-2). It is not easy to access or reset (you must remove the top cover, a bracket, and the A3 assembly). Therefore, unless one of the following conditions exist, don’t change it. Reasons to suspect these switches are set incorrectly include:

Time domain response of the test set can be used to identify problems in the RF path. The plots below show typical time domain responses of the HP

8512A, 8513A,

8514A/B, and 8515A test sets. These can

be used as rough standards when trying to locate a problem in the RF path. Keep in mind that the absolute location in time and absolute height of the responses will vary from test set to test set. The significant factor is the relative height of the main impulse (determined by the calibrated short) and the discontinuities. Discontinuities that may be causing a problem will usually stand out as being much greater than the typical response.

Unratioed Power Test

This procedure allows you to check the output power level of each test set sampler/mixer assembly and its associated IF amplifier alone. The normal power level display, case,

The network analyzer automatically powers and phase-locks a predefined port or ports to

make the measurement selected.

Sll

for example, is a ratio (in this

Ratioed

measurements provide useful data but they can mask certain malfunctions. Assume, for example, the task is to measure an S-parameter at a specific power level. If the test set has a 20 dB power hole due to a faulty RF input connector, that deficiency would be invisible (ratioed out) in a ratioed measurement. But the data would be incorrect; it would not have been taken at the specified power level.

Similarly, troubleshooting system faults in a ratioed measurement mode can be deceptive. The solution

is to check each channel singly, to check the power in an unratioed mode. To do so requires specifying

which port to drive power to and which channel to achieve phase lock with. The following procedures include steps to redefine parameters as required.

Figures 5-13 through 5-18 show which assemblies are parts of the signal path of each channel.

Realizing that some assemblies are common to two, or all four, channels is a powerful troubleshooting

tool. Figures 5-11 and 5-13 through 5-18, following these procedures, show typical traces.

IF ANY USER CHANNEL LOOKS BAD

One or more user channels appear faulty. The question is, what is at fault?, the source or test set or IF/ detector (HP 85102). The service adapter is a source/test set emulator. It provides the same 20 MHz signal to the HP 85102B as the test set and source. Thus it indicates whether the problem is in the IF/ detector.

Section 6. Replaceable Parts

INTRODUCTION

This section contains information for ordering parts. Exchange Assemblies Available describes how to order assemblies which are available on an exchange basis. Table 6-1 is a list of manufacturers (by code number) and reference designations.

HP8514B replaceable parts are identified by Table 6-2 and Figures 6-l through 6-7.

HP8512A replaceable parts are identified by Table 6-3 and Figures 6-3, 6-4 and 6-8 through 6-10.

EXCHANGE ASSEMBLIES AVAILABLE

The items below are replaceable on a rebuilt exchange basis at a cost saving. They are not

field-

repairable. Defective assemblies must be returned for credit to realize the cost savings. Thus, assemblies required for spare parts stock should be ordered by the new assembly part number which is included in the replaceable parts list of this section. See the parts list for the orderable part numbers.

The replaceable parts lists consist of illustrations and tables. Use the illustrations to identify the part to

be ordered; use the tables to determine the ordering information. Each table is arranged in alpha- numerical order by reference designator. The reference designator keys the part listed to the illustra-

tion. The first part number listed is HP’s part number and may differ from the manufacturer’s part

number. The check digit serves as an error check of the part number and should be used when ordering a part. Quantity refers to the total number of that part in the instrument. The description is a brief written description of the part and may be used for ordering purposes. Manufacturers code is a five digit number assigned to each manufacturer (identified in Table 6-l). The manufacturer part number may or

may not be the same as the HP part number. The replaceable parts of ports 1 and 2 of the HP 8514B are identified in Figure 6-6. The replaceable parts of ports 1 and 2 of the
