PRODUCT
DESCRIPTION The HP 41952A and HP 41952B Transmission/Reflection Test
Sets are used with the HP 4195A to perform both transmission
and reflection measurements. The HP 41952A Is used for 50(1
applications and the HP 41952B is used for 75n applications.
Using two HP 41952A or HP 41952B test sets, full ¶meter
measurements can be performed. The following are the main
feature of the HP 41952A/B.
• Frequency rat* : 100 kHz to 500 MHz
• Directivity : 40 dB (HP 41952A, 300 kHz to 200 MHz)
• Effective Source Match : Z 20 dB (300 kHz)
• Direct connection to the HP 4195A

SAFETY
CONSIDERATIONS The HP 41952A/B Transmisslon/Reflection Test Sets conform to
the safety requiremcnts for IEC 348, and CSA 556B instruments,
and is 'shipped from the factory in a safe condition. This opera-
tion note contains information, CAUTIONS and WARNINGS which
must be followed by the user to ensure safe operation,
UNITS COVERED BY
THIS OPERATION
NOTE
Hewlett-Packard uses a two-part, nine character serial number
which is stamped on the serial number plate (see Figure 1-1)
attached to the inside of the carrying case. The first four digits
and a letter are the prefix and the last five digits are the suffix of
the serial number, The letter in the serial, number identifies the
country where the instrument was manufactured. The prefix is
same for all identical instruments, it changes only when a change
Is made to the instrument. The suffix, however, is assigned
sequentially and is different for each Instrument. This operation
note applies to instruments with serial number prefixes listed
under Serial Numbers on the title page.
Figure 1-1. Serial Number Plate
Units manufactured after this operation note was printed may
have a serial number prefix which is not listed on the title page.
An unlisted serial number prefix indicates that the instrument may
be different from those described in this operation note. Opera-
tion notes for new instruments may be accompanied by a yellow
Manual Supplement page, or have a different part number, This
supplement contains "Change Information" explaining how to
adapt this operation note to newer instruments.

This section provides the following information.
The HP 41952A/B Transmission/RefrectIon Test Sets meet all of
the specifications listed in Table 1.3. Upon receipt, Inspect the
shipping container for damage. If the shipping container or the
cushioning material has been damaged, beep the' container and
packing material until the contents have been checked for com-
pleteness and the test set has been checked oit mechanically
and electrically. Figure 2-1 shows the product, overview., The

shipment when necessary. 1
Original
Pakaging Containers and packing material Identical to those'used in factory
packaging are available from Hewlett-Packard. if the unit Is being
returned to Hewlett-Packard for servicing, attach,a tag Indicating
the type of service required, return address, model number and
full serial number,
Other
Packaging The following general instructions should be used for repacking
; with commercially available materials.
1. Wrap the unit in hea(ey paper or plastic. It shipping to a
HP sales office or service center, attach a tag indicating
the type of service required, return address, model num-
ber and full serial number.
2. Use a strong shipping container. A double-walled carton
made of 350 pound test material Is adequate.
3. Use enough shock absorbing material (a 3 to 4 inch layer)
around all sides of the' unit to provide a film cushion and
to prevent the unit, from moving inside the container.
4. Seal the shipping container securely.
5. Mark the shipping container FRAGILE to ensure careful
handling.
6. In any correspondence, refer to unit by Its model number
and the full serial number.

(1) RF INPUT connector : 600 N(f) connector
The output signal from HP 4195A's OUTPUT Si , or S2 Is input
through the RF ,INPUT connector, the signal is then split and fed
to the INCIDENT and TEST PORT / REFLECTED connectors
(2) INCIDENT connector : 600 N(m) connector
This connerttor is used to route a portion (INCIDENT) of the OUT-
PUT S1 or S2 signal to the HP 4195A's INPUT R1 or R2. This
signal Is Used as the refejence sIgnal for ratio measurements.
(3) REFLECTED connector : 500 N(m) connector
This connector is used to route' the REFLECTED sigmil from the
DUT to the HP 4195A's INPUT T1 or '1"2.
(4) TEST PORT connector :HP 41952A :500 NO) connector
:HP 41952B :750 N(I) connector
This connector' Is used to route the OUTPUT signal to the OUT
and to receive the REFLECTED signal from the OUT.
(5) Semi-rigid cable :1.00 N(m)-N(m) cable
This cable is used to connect HP 4195A OUTPUT S1 or S2 to the
HP 41952A/13's RF1NPUT.
CAUTION1
Do not apply signals with power levels exceeding +23 dBm
to the RF INPUT and TEST PORT connectors, or damage
may result.
ICAUTION
Do not mate a 500 type-N connector to a ma type-N con-
nector or damage may result.

CALIBRATION
CONSIDERATIONS The HP 4195A provides calibration capabilities for enhancing
measurement accuracy. You can select from the following call-
bration functions (appropriate for your measurement) to compen-
sate for errors due to the test set. Refer to the HP 4195A Opera-
tion Manual for details.
• For Transmission Measrements
• Normalize (Through) Calibration:
Compensates frequency response errors.
• Normalize & Isolation Calibration:
Compensates frequency response and crosstalk
errors. 1
• For Reflection Measurements
• NorMalize (Open\ Calibration:
ComOnsates trequency response lors.
• One Pail Partial Calibration:
Compensate, frequency response and directivity
errors.

INTRODUCTION This section provides the performance test procedure to ensure
that the HP 41952A/B meets the specifications listed in Table 1-3,
Specifications. The performance test can be performed without
accessing the interior of the HP 41952A/B.
The test results should be recorded into the Performance Test
Record located at the end of this section.
EQUIPMENT REQUIRED
The equipment required for performance testing is listed in Table
4-1. Substitutions can be made for the equipment in this list if
the specifications meet or exceed the specifications listed in the
Requirements column.

CALIBRATION CYCLECYCLE
The HP 41952A/3 requires periodic performance Verification. The''
HP 41952A/B bliould be checked out using the performance test
at least once a year or more depending on the frequency of use. ,
Preventive maintenance should be performed at least twice a year
to keep dowtt-time to a minimum, and to insure optimum
operation.
PREPARATION This paragraph provides the information you need to know, and
the steps you must perform before starting the performance test.
1, The test equipment must be allowed to warm-up and stabilize
for at least 30 minutes.
2. An HP 4195A Is required to performance test the HP 41952A/
B, In the remainder of this manual, the HP 4195A's softkeys
are indicated in boldface type and are enclosed In single
quotes (e.g., 'NETWORK' soltkey), and keys are indicated in
bold face type only (e,g., PRESET key).
3. The HP 4195A's calibration capability Is used to performance
test the HP 41952A/B. Perform the procedure given below to
change the calibration standard data stored In the HP 4195A
before running the performance test. If you are testing a
HP 41952A, perform steps a and b. I: you are testing a
HP 41952B, perform steps a through d,
a, Turn the HP 4195A ON, and sequentially press the PRE-
SET and CAL keys, and the 'more 112' and 'CAL STD
