General Information
Preventive Maintenance
Preventive Maintenance
The best techniques for maintaining the integrity of the components include:
• routine visual inspection
• routine cleaning
• proper connection techniques
All of these are described in Chapter 3. Failure to detect and remove dirt or metallic particles on a mating
plane surface can degrade repeatability and accuracy and can damage any component mated to it. Improper
connections resulting from poor connection techniques, can also damage these components.
When to Calibrate the Analyzer
An analyzer calibration remains valid as long as the changes in the systematic error are insignificant. This
means that changes to the uncorrected leakages (directivity and isolation), mismatches (source match and
load match), and frequency response of the system are small (<10%) relative to accuracy specifications.
Change in the environment (especially temperature) between calibration and measurement is the major
cause in calibration accuracy degradation. The major effect is a change in the physical length of external and
internal cables. Other important causes are dirty and damaged test port connectors and calibration
standards. If the connectors become dirty or damaged, measurement repeatability and accuracy is affected.
Fortunately, it is relatively easy to evaluate the general validity of the calibration. To test repeatability,
remeasure one of the calibration standards. If you can not obtain repeatable measurements from your
calibration standards, maintenance needs to be performed on the test port connectors, cables and
calibration standards. Also, maintain at least one sample of the device under test or some known device as
your reference device.
How to Calibrate the Analyzer
Your analyzer’s calibration user interface prompts you through each step in a 1-port or a 2-port calibration
procedure. For detailed information on using your analyzer, refer to the appropriate user guide. See “Where
to Look for More Information” on page 4-3.

Temperature—What to Watch Out For
Changes in temperature can affect electrical characteristics. Therefore, the operating temperature is a
critical factor in performance. During a measurement calibration, the temperature of the calibration
components must be stable and within the range shown in
Tab le 2- 1.
IMPORTANT Avoid unnecessary handling of the components during calibration because your fingers act
as a heat source and may increase the temperature of the component.

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
components 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 having a 1 MW 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.
• always ground yourself before you clean, inspect, or make a connection to a static-sensitive device or
test port. You can, for example, grasp the grounded outer shell of the test port or cable connector briefly.
• always ground the center conductor of a test cable before making a connection to the analyzer test port
or other static-sensitive device. This can be done as follows:
1. Connect a short to one end of the cable to short the center conductor to the outer conductor.
2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.
3. Connect the other end of the cable to the test port.
• Remove the short from the cable.
Figure 3-1 shows a typical ESD protection setup using a grounded mat and wrist strap.

Use, Maintenance, and Care of the Components
Visual Inspection
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 component performance. A
damaged mating surface can damage any good surface connected to it. If necessary, clean all mating
surfaces.
Magnification is helpful when inspecting mating surfaces, but it is not required and may actually be
misleading. Defects and damage that cannot be seen without magnification generally have no effect on
electrical or mechanical performance. Magnification is of great use in analyzing the nature and cause of
damage and in cleaning mating surfaces, but it is not required for inspection.

Use, Maintenance, and Care of the Components
Cleaning the Mating Plane Surfaces
Cleaning the Mating Plane Surfaces
1. Use Compressed Air or Nitrogen
WARNING Always use protective eyewear when using compressed air or nitrogen.
Use compressed air (or nitrogen) to loosen particles on the mating plane surfaces. Clean air cannot
damage a component 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 kPa
(60 psi) to control the velocity of the air stream. High-velocity streams of compressed air can cause
electrostatic effects when directed into a component. These electrostatic effects can damage the
component. Refer to “Electrostatic Discharge” earlier in this chapter for additional information.
WARNING Keep 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 Mating 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 component before you reassemble
or use it.
3. Inspect
a. Inspect the mating plane surface to make sure that no particles or residue remain. “Visual
Inspection” on page 3-3.

Connections
Connections
Good connections require a skilled operator. Slight errors in operator technique can have a significant effect
on measurements and measurement uncertainties. The most common cause of measurement error is poor
connections.
The following procedures illustrate how to make good connections.
IMPORTANT Unlike threaded components, the WR-90, WR-62, WR-42 waveguide mating planes are
flanges that you must carefully screw together. Always connect waveguide in the same
flange orientation. For example, use the label as a reference and always connect
components with the labels facing the same direction.
Aligning Two Precision Flanges
A precision flange has two precision alignment holes, as shown in Figure 3-2. A non-precision flange has
only screw holes.

Use, Maintenance, and Care of the Components
Connections
1. Place the slip pins in the top and bottom holes of one flange, as shown in Figure 3-3.
Figure 3-3 Inserting Slip Pins
2. Using the pins as guides for the adapter, offset shim, and waveguide-to-coax adapter, carefully align the
flanges and insert two screws in the diagonal corner holes, as shown in Figure 3-4.
Figure 3-4 Aligning Flanges
3. Place a lock washer and nut on each screw, and finger tighten.
4. Insert the remaining two screws.
5. Place a lock washer and nut on each screw, and finger tighten.
6. Remove the slip pins.
7. Go to “Tightening a Flange Connection” on page 3-7.

Tightening a Flange Connection
NOTE The best connection has symmetrical pressure applied as you gradually tighten the screws.
1. In an “X” pattern (for equal compression), tighten all four screws using a hex ball driver. Do not
over-tighten. See Figure 3-5.
2. Visually inspect the connection. Refer to the following section “Inspecting a Flange Connection.”
Figure 3-5 “X” Screw Pattern
Inspecting a Flange Connection
Inspect the flange connection as follows:
1. Place an electric light or white paper behind the connection.
2. Check the flange matings for any gap. A good connection has no gaps between the connected
waveguide flanges, and the waveguide walls are flush. There is no step or offset.
3. Ensure that all four screws are equally tight.

Handling and Storage
Handling and Storage
• Install the protective end caps and store the calibration components when not in use.
• Never store components loose in a box, or in a desk or bench drawer. This is the most common cause of
component damage during storage.
• Keep components clean.
• Do not touch mating plane surfaces. Natural skin oils and microscopic particles of dirt are easily
transferred to a component and are very difficult to remove.
• Do not set components 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.
