Principles of Microwave Connector Care

Proper connector care and connection techniques are critical for accurate,

repeatable measurements.

Refer to the calibration kit documentation for connector care information.

Prior to making connections to the network analyzer, carefully review the

information about inspecting, cleaning and gaging connectors.

Having good connector care and connection techniques extends the life of these

devices. In addition, you obtain the most accurate measurements.

This type of information is typically located in Chapter 3 of the calibration kit

manuals.

For additional connector care instruction, contact your local Hewlett-P

Sales and Service Oce about course numbers HP 85050A+24A and

HP 85050A+24D.

See the following table for quick reference tips about connector care

ackard

Handling and Storage

Do Do Not

Keep connectors clean Touch mating-plane surfaces

Extend sleeve or connector nut Set connectors contact|end down

Use plastic end-caps during storage

Visual Inspection

Do Do Not

Inspect all connectors carefully Use a damaged connector|ever

Look for metal particles, scratches, and dents

Connector Cleaning

Do Do Not

Try compressed air rst Use any abrasives

Use isopropyl alcohol Get liquid into plastic support beads

Clean connector threads

Gaging Connectors

Do Do Not

Clean and zero the gage before use Use an out-of-spec connector

Use the correct gage type

Use correct end of calibration block

Gage all connectors before rst use

Making Connections

Do Do Not

Align connectors carefully Apply bending force to connection

Make preliminary connection lightly Over tighten preliminary connection

Turn only the connector nut Twist or screw any connection

Use a torque wrench for nal connect Tighten past torque wrench \break" point

System Verication and Performance

Tests

How to Test the Performance of Your Analyzer

To obtain the same quality of performance testing that Hewlett-Packard has

administered at the factory, you must perform:

the system verication procedure

AND

all

of the performance test procedures.

This quality of performance testing guarantees that the analyzer is performing

within

will issue a Certicate of Calibration for your analyzer if two conditions are

met:

all

of the published specications. A Hewlett-Packard Customer Engineer

Your analyzer passes all the performed tests.

The equipment and standards that were used to perform the tests are

traceable to a national standards institute.

Note

If you have a particular type of measurement application that

does not use all of the analyzer's measurement capabilities,

you may ask your local Hewlett-Packard Customer Service

Center for a subset of specications that you want veried.

However, this does create the potential for making incorrect

measurements when using a dierent application.

(supplied in the HP 85032B 50 type-N calibration kit or the HP 85036B 75

type-N calibration kit) and comparing the measured data to the specication

limits drawn on the analyzer display. The measured data must fall within the

specication limits at all frequencies to pass the test.

System verication is only part of an instrument's calibration procedure.

The complete set of instrument specications can be tested by performing

the \HP 8752C System Verication" and all of the analyzer's performance

tests. An HP 85032B Option 002 or an HP 85036B Option 1BP calibration kit

(including with a Certicate of Calibration with United States National Institute

of Standards and Technology (NIST) test numbers) is required for a calibration

traceable to NIST.

Note

A Certicate of Calibration is issued if the analyzer's system

verication as well as all of the performance tests are

performed by a Hewlett-Packard Customer Engineer with all

having passed.

System Verication and Performance Tests 2-3

System Verication Cycle and Kit Recertication

The recommended system verication cycle is every six months. Hewlett-

Packard also suggests the calibration kit be recertied annually.For more

information about the kit recertication, refer to the

HP 85032B 50 Type-N

Calibration Kit Operation and Service Manual

Measurement Uncertainty

Associated with any analyzer are measurement errors that add uncertainty to

the measured results. This uncertainty limits how accurately a device under test

(DUT) can be measured.

The measurement uncertainty is dened to be the sum of the residual

systematic (repeatable) and random (non-repeatable) errors in the measurement

system. The systematic errors are eective directivity, eective source match,

load match, reection and transmission tracking, and isolation (crosstalk).

Random errors include errors due to noise, drift, connector repeatability, and

test cable stability.

The typical measurement uncertainties for type-N connectors using a

1-port error correction utilize an RSS (Root Sum of Squares) model for the

contributions of random errors such as noise, pin depth, pin diameter variation,

load return loss, and connector repeatability.

Measurement Uncertainty Window

The PASS/FAIL result of the limit line test generally indicates the status of the

verication test. The validity of the limit lines, drawn on the analyzer display

during the verication tests, are determined by the measurement uncertainty.

The measurement uncertainty must be taken into account when analyzing

the test results. If the analyzer detects the test data outside of the limits,a

FAIL

will be displayed on the analyzer. This

FAIL

status may not represent

a true failure if at the worst point, the test data is within the measurement

uncertainty window (not displayed on the analyzer). Refer to Figure 2-1 for

interpretations of test data.

Description

This test determines the reection test port output power range and level

linearity for all analyzers without Option 004. The specications are veried

by rst setting a reference at05 dBm for relative power measurements. Next,

the analyzer's reection test port output power is stepped and measured over

its operating power range. The power level linearity is found by calculating the

dierence between the power meter reading and the power oset listed in the

This test measures the system trace noise at a designated CW frequency in both

the transmission and reection modes. It is performed at the instrument's

highest CW frequency since this is the worse case for the system trace noise.

For an analyzer with Options 003 and 075, a CW frequency of 2 GHz is selected

instead of 3 GHz.
