CALIBRATION
CONSIDERATIONS
The HP 4195A provides calibration capabilities for enhancing
measurement accuracy. You can select from the following calibration 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.
l
For Transmission Measurements
. Normalize (Through) Calibration:
Compensates frequency response errors.
l
Normalize & Isolation Calibration:
Compensates frequency response and crosstalk
errors.
l
For Reflection Measurements
l
Normalize (Open) Calibration:
Compensates frequency response errors.
. One Port Partial Calibration:
Compensates frequency response and directivity
errors.

The standard values for reflection calibration are stored In the
HP 4195A’S memory, and these values can be modified to match
,,“,your standards. Use the values listed in Table 3-1 for the stan-
dard values when using the HP 880328 of HP 850368 callbratlon

PERFORMANCE TESTS
SECTION 4
INTRODUCTION
This section provides the performance test procedure to ensure
that the HP 41952A/B meets the specifications listed in Table i-3.
Specifications. The performance test can be performed without
accessing the interior ot the HP 41952A/B.
The test results should be recorded into the Performance Test
Record located at the end of this section.
EQUlPMENT 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
Reauirements column.

CALIBRATION CYCLE
The HP 41952A/B requires periodic performance verification. The
HP 41952A/B should 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 down-time to a minimum, and to ,lnsure optimum
operation.

PREPARATION
t
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 4t952A/
6. 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’ softkey). 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 teat. If you are testing a
HP 41952A. perform steps a and b. If you are testing a
HP 419528. perform steps a through d.
a. Turn the HP 4195A ON. and sequentially press the PAE-
SET and CAL keys, and the ‘more, 112’ and ‘CAL STD
