Calibration Devices and Their Use
Calibration Devices and Their Use
The R, Q, U, V, and W11644 waveguide calibration kits may contain some or all of the
following: short, standard section, termination loads, wavelength shim, and waveguide
straights.
The following briefly describes the design and construction of all the calibration kit
devices.
Short
A short is also called a flush short. It is connected directly to the test port, or used as an
offset short when combined with the ¼ wavelength shim.
Standard Section
A standard section is used to check system operation after you complete a calibration.
Termination
A termination is also called a load. It is connected directly to the test port, or used as an
offset load when combined with the ¼ wavelength shim.
¼ Wavelength Shim
A ¼ wavelength shim is also called an offset, or ¼ wavelength section. The shim is
terminated by the short, fixed load, or the second test port of the analyzer.
Waveguide Straight Section (verification device)
A waveguide straight is included as a system verification device. Be sure to keep it
protected from wear and damage. When using it, always connect the same side, in the
same orientation, for consistent and accurate mating.
Waveguide Straight Section (port 1 and 2)
Two waveguide straights, provided in this kit, are used as port 1 and port 2 measurement
planes when properly connected to the directional couplers. Because these straight
sections are used as port 1 and port 2 for device connections, they reduce wear that would
otherwise occur to the coupler flanges. These particular straights should be replaced or
renewed whenever the calibration devices are replaced or renewed.

Electrostatic Discharge
Electrostatic Discharge
Protection against electrostatic discharge (ESD) is essential while connecting, inspecting,
or cleaning connectors attached to a static-sensitive circuit (such as those found in test
sets).
Static electricity can build up on your body and can easily damage sensitive internal
circuit elements when discharged. Static discharges too small to be felt can cause
permanent damage. Devices such as calibration c omponents and devices under test (DUT),
can also carry an electrostatic charge. To prevent damage to the test set, components, and
devices:
• Always wear a grounded wrist strap havi ng a 1 MΩ resistor in series with it when
handling components and devices or when making connections to the test set.
• Always use a grounded antistatic mat in front of your test equipment.
• Always wear a heel strap when working in an area with a conductive floor. If you are
uncertain about the conductivity of your floor, wear a heel strap.
Figure 4-1 shows a typical ESD protection setup using a grounded mat and wrist strap.
Refer to Table 7-6 o n page 7-14 for information on ordering supplies for ESD protection.
Figure 4-1ESD Protection Setup
Visual Inspection
Visual inspection and, if necessary, cleaning should be done every time a connection is
made. Inspect mating surfaces for dirt, dust, foreign particles, or scratches, which can
degrade dev ice performance. A damaged mat ing surface ca n damage any go o d su rface
connected to it. If necessary, clean all mating surfaces.

Cleaning the Mating Plane Surfaces
Cleaning the Mating Plane Surfaces
1. Use Compressed Air or Nitrogen
WARNINGAlways use protective eyewear when using compressed air or
nitrogen.
Use compressed air (or nitrogen) to loose n particles on the mating plane su rfaces. Cl ean
air cannot damage a device or leave particles or residues behind.
You can use any source of clean, dry, low-pressure compressed air or nitrogen that has
an effective oil-vapor filter and liquid condensation trap placed just before the outlet
hose.
Ground the hose nozzle to prevent electrostatic discharge, and set the air pressure to
less than 414 kP a (6 0 psi) to c ontrol the v elocity of the air stream. High-veloci ty streams
of compressed air can cause electrostatic effects when directed into a device. These
electrostatic effects can damage the device. Refer to “Electro stati c Disc harge ” earlier in
this chapter for additional information.
WARNINGKeep isopropyl alcohol away from heat, sparks, and flame. Store in a
tightly closed container. It is extremely flammable. In case of fire, use
alcohol foam, dry chemical, or carbon dioxide; water may be
ineffective.
Use isopropyl alcohol with adequate ventilation and avoid contact
with eyes, skin, and clothing. It causes skin irritation, may cause eye
damage, and is harmful if swallowed or inhaled. It may be harmful if
absorbed through the skin. Wash thoroughly after handling.
In case of spill, soak up with sand or earth. Flush spill area with
water.
Dispose of isopropyl alcohol in accordance with all applicable
federal, state, and local environmental regulations.
2. Clean the Mat ing Plane Surfaces
a. Apply a small amount of isopropyl alcohol to a lint-free cleaning swab.
b. Clean the mating plane surfaces.
c. Let the alcohol evaporate, then blow the mating plane surface dry with a gentle
stream of clean, low-pressure compressed air or nitrogen. Always completely dry a
device before you reassemble or use it.
3. Inspect
a. Inspect the mating plane surface to make sure that no particles or residue remain.

Handling and Storage
Handling and Storage
• Install the protective end caps and store the calibration devices in the foam-lined
storage case when not in use.
• Never sto re de vices loose in a bo x, o r in a de sk or bench drawer. This is the most
common cause of device damage during storage.
• Keep devices clean.
• Do not touch mating plane surfaces. Natural skin oils and microscopic particles of dirt
are easily transferred to a device and are very difficult to remove.
• Do not set devices contact-end down on a hard surface. The plating and the mating
plane surfaces can be damaged if the interface comes in contact with any hard surface.

Performance Verification
Introduction
Introduction
The performance of your calibra tion kit can only be verified by retur ning the kit to Agilent
Technologies for recertification. The equipment and calibration standards required to
verify the specifications of the limits of the devices in the kit have been specially
manufactured and are not commercially available. However, you may check the
performance of the terminations in this kit by following the procedure “Termination
Return Loss Measurement” on page 5-4.
To confirm that your calibration kit is performing accurate calibrations, use the
appropriate Agilent 11645A verification kit with the “Specificatio ns & Per formanc e
Verification” disk included in this kit.
How Agilent Verifies the Devices in Your Kit
Agilent verifies the specifications of these devices as follows:
1. The residual microwave error terms of the test system are verified with precision
airlines and shorts that are directly traced to the National Institute of Standards and
Tec hnology (NIST). The airline and short characteristics are developed from mechanical
measurements. The mechanical measurements and material properties are carefully
modeled to give very accurate electrical representa tion. The mechanical measurements
are then traced to NIST through various plug and ring gages and other mechanical
measurements.
2. Each calibration device is electrically tested on this system. For the initial (before sale)
testing of the ca li brat ion de vi ces , Agilent includes the test measurement uncer tainty a s
a guardband to guarantee each device meets the published specification. For
recertifications (after sale), no guardband is used and the measured data is compared
directly with the specification to determine the pass or fail status. The measurement
uncertainty for each device is, however, recorded in the calibration report that
accompanies recertified kits.
These two steps establish a traceable link to NIST for Agilent to the extent allowed by the
institute’s calibration facility. The specifications data provided for the devices in the kit is
traceable to NIST through Agilent Technologies.

Recertification
Recertific at ion
The following will be provided with a recertified kit:
• a new calibration sticker affixed to the case
• a certificate of calibration
• a calibration report for each device in the kit listing measured values, specifications,
and uncertainties
NOTEA list of NIST traceable numbers may be purchased upon request to be
included in the calibration report.
Agilent Technologies offers a Standard calibration for the recertification of the kit. For
more information, contact Agilent Technologies. Refer to “Contacting Agilent” on page 6-4
for a lis t o f o ffices.
How Often to Recertify
The suggested initial inter val fo r recertifi cation i s 12 months or sooner. The actual need for
recertification depends on the use of the kit. After reviewing the results of the initial
recertification, you may establi sh a different recertif ication inter val that reflects the usage
and wear of the kit.
NOTEThe recertification interva l should begin on the date the kit is first used after
the recertification date.
Where to Send a Kit for Recertification
Contact Agilent Technologies for information on where to send your kit for recertification.

Standard Definitions
Nominal Standard Defini ti ons
Nominal Standard Definitions
Standard definitions provide the constants needed to mathematically model the electrical
characteristics (delay, attenuation, and impedance) of each calibration standard. The
nominal values of these constants are theoretically derived from the physical dimensions
and material of each calibr ation standard, o r from actual measured re sponse. T hese values
are used to determine the measurement uncertainties of the network analyzer. The
standard definitions in Tabl es A-6 through A-15 list typical calibration kit parameters
used by the 8510, 872x, and PNA series to specify the mathematical model of each device.
This information must be loaded into the network analyzer to perform valid calibrations.
Refer to your network analyzers user’s guide for instructions on loading calibration
definitions.
NOTEThe values in the standard definitions table are valid only over the specified
operating temperature range.
Setting the System Impedance
This kit contains only 50 ohm devices. Ensure the system impedance (Z0) is set t o 5 0 ohms .
Refer to your network analyzer user’s guide for instructions on setting system impedance.
Version Changes
Class assi gn ments and stan dard defini tio n s may change as mo re accurate mo de l and
calibration methods are developed . The disk shipped with the kit for use with the 8510 wil l
contain the most recent version. The default version that comes with the 872x network
analyz e r firmware may be outdated.
