INSTRUMENTS COVERED BY MAN UAL
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 Serial Numbers.
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.
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.
DESCRI PT ION AND OPERAT ING CHARACTERI STI CS
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
GHz. This
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:
l four RF to IF converters to measure all four S-parameters without reconnecting the DUT,
l two 90 dB programmable step attenuators for changing (in 10 dB steps) the incident power
level at both ports,
l two bias tees for applying external dc bias to both test port center conductors.
1-2
General Information HP
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:
l
three RF to IF converters, for making reflection (S,,) and transmission (S,,) measurements,
l
no step attenuators to internally change the incident power level,
l
no bias tees to apply external DC bias to the test port center conductors.
Tables 1 and 1B list additional characteristics of the HP85148 and 8512A, respectively. Figure l-2
shows the HP 8514B in a typical measurement set-up.

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.
Option 908
This option supplies the test set with the parts required to rack mount it with handles removed. Refer to
the installation section of this manual for additional information.
Option 910
This option provides a duplicate test set manual.
Option 913
This option supplies the test set with the parts required to rack mount it with handles. Refer to the
INSTALLATION section of this manual for additional information.
Option W03 , Warra nty Conversion
Option W03 converts the standard one year return to Hewlett-Packard warranty to a 90 day on-site
warranty. W03 can only be ordered at the time of instrument purchase. Instruments ordered with option
W03 are identified on the serial number label, or on a special identification label supplied with the
instrument.
Option W30 , Ext ende d Servic e

The recommended rack is the HP85043A. Instructions for rack mounting the test set in a system
configuration with the HP8510 are provided in the HP8570 installation section and in the HP85043A
System Rack Manual.
Sta tic Free Worksta tion
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.

Mating Connectors.
HP 8514B PORTS 1 and 2 are precision 3.5 mm male connectors and mate with
precision 3.5 mm female connectors. The HP 8512A has 7 mm test port connectors.
The TEST SET INTERCONNECT connector is a series D subminature female connector with 7 RF
connections.
The 8510 SYSTEM BUS connector is a female HPIB type connector and mates with the corresponding
male connectors of HPIB cables.
Power and Control Connections.
Figure 2-4 shows the following connections (with the exception of
line power) and the required RF source connections.
Connect the power cord to an electrical outlet and the line module to supply power to the test set.
Connect the test set IF interconnect cable from the Jll TEST SET INTERCONNECT connector on the
rear panel of the test set to the Jl TEST SET INTERCONNECT connector on the rear panel of the
HP85102 IF Detector.
2-4 Installation 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 connec-
tion.
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).
PACKAGIN G
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 anti-
static 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.

Section 3. Operation
This section illustrates the features and functions of the front and rear panels of the HP 8514B and
8512A test sets. It also includes an operator’s check procedure. The function of the operator’s check is
to confirm that the HP 8514B and HP 8512A test sets function properly as part of an HP 8510 system.
The performance tests documented in the HP 85708 System Manual and volume 2 of the HP851OA
manual set are a more rigorous check. Volume 2 of the HP8510A manual set documents the HP8512A
only.
l Also included in this section: a description of the Multiple Test Set Option (Option 001).

This LED lights about two seconds after power
is turned on, following the successful conclusion of self-test.
4. Port 1.
This test port transmits RF energy from the source
to the DUT and receives reflected RF energy from the DUT.
The reflected RF energy is coupled to a sampler within the
instrument.
5. Bias Fuse. (HP8514B only) The fuse which limits bias
applied to Port 1 is within this holder (see the instrument
front panel or the replaceable parts list for the value of the
fuse
Fl).

(HP8514B only) The fuse which limits bias
applied to Port 2 is within this holder (see the instrument
front panel or the replaceable parts list for the value of the
fuse F2).
9. Port 2. In the
HP6514B, this test port transmits RF energy
from the source to the DUT and receives reflected RF energy
from the DUT.
In the HP8512A, this port only receives transmitted (from
Port 1) RF energy. The received RF energy is input directly to
a sampler within the instrument.
