Section 1. General Information
The purpose of this manual is to enable you to use your HP 8514B S-parameter or HP 8512A reflection/
transmission test set effectively and confidently. These test sets are integral components of the
HP8510 measurement system. For that reason, this manual has been divided into two major portions
(Operating and Service) to be an integral part of the HP8510 documentation.

VERIFYING THE TEST SET
The HP8514B and HP8512A have been designed to operate specifically with the HP8510 network
analyzer.
0 To install the instrument, turn to the Installation section of this manual.
l To check the proper operation of the test set, see the Operator’s Check in the Operation section of
this manual.
l To see the specifications of the test set refer to Specifications in the HP8570B System Manual or
Genera/ information in volume 1 of the HP 8510A manual set.

l To verify that the instrument meets its published specifications, turn to the Performance Tests
section in the HP8510B System Manual or Volume 2 of the HP851OA Operating and Service Manual.
Note that the HP8514B can be performance tested only to 18 GHz with the HP851OA software.
l To troubleshoot the test set, refer to the Service Overview section and the TestSet Troubleshooting
section of the HP8510B Service Manual. Or refer to the Service section in Volume 4 of the HP851OA
Operating and Service Manual. Otherwise call your local Hewlett-Packard office.
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.

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
Option W30 adds two additional years of return-to-HP service, to follow the first year of warranty.
Option W30 can be ordered only at the time of purchase. Instruments ordered with option W30 are
identified on the serial number label, or on a special identification label supplied with the instrument.
NOTE: additional system warranty information is included in the HP8510 manual set.
