Use, Maintenance, and Care of the Devices
Electrostatic Discharge
Electrostatic Discharge
Protection against ESD (electrostatic discharge) 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 (DUTs), 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 Mresistor in series with it when handling components
and devices or when making connections to the test set.
•always use a grounded, conductive table mat while making connections.
•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 (from your calibration kit) 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.
4. Remove the short from the cable.
Refer to Chapter 6 for part numbers and instructions for ordering ESD protection devices.

Use, Maintenance, and Care of the Devices
Visual Inspection
Visual Inspection
Examine the mating surfaces first for obvious defects or damage. If necessary, cleaning should be done
every time a connection is made. Metal particles or dirt may fall onto the mating surface during the
connection and disconnection process.
CAUTION Devices with damaged mating surfaces should be immediately discarded or clearly marked
and set aside for repair. A damaged device will in turn damage any good device to which it is
attached. Determine the cause of the damage before connecting a new, undamaged device
in the same configuration.
In some cases, magnification is necessary to see damage to a connector; a magnifying device with a
magnification of 10x is recommended. However, not all defects that are visible only under magnification
will affect the electrical performance of the connector. Use the following guidelines when evaluating the
integrity of a connector.
What Causes Mating Surface Wear?
Mating surface wear is caused by connecting and disconnecting the devices. The more use a device gets,
the faster it wears and degrades. The wear is greatly accelerated when mating surfaces are not kept clean,
or are not connected properly.
Mating surfacer wear eventually degrades performance of the device. Calibration devices should have a long
life if their use is on the order of a few times per week. Replace devices with worn mating surfaces.
The test port connectors on the PNA test set may have many connections each day, and are, therefore, more
subject to wear. It is recommended that an adapter be used as a test port saver to minimize the wear on the
test set’s test port connectors.
Inspect the Mating Plane Surfaces
Flat contact between the mating plane surfaces is required for a good connection. Look especially for deep
scratches or dents, and for dirt and metal particles on the mating plane surfaces. Also look for signs of
damage due to excessive or uneven wear or misalignment.
Light burnishing of the mating plane surfaces is normal, and is evident as light scratches or shallow marks
distributed more or less uniformly over the mating plane surface. Other small defects and cosmetic
imperfections are also normal. None of these affect electrical or mechanical performance. If a mating
surface shows deep scratches or dents, clinging particles, or uneven wear, clean and inspect it again.

Use, Maintenance, and Care of the Devices
Cleaning the Mating Plane Surfaces
Cleaning the Mating Plane Surfaces
1. Use Compressed Air or Nitrogen
Clean mating surfaces are essential for ensuring the integrity of the waveguide.
WARNING Always use protective eyewear when using compressed air or nitrogen.
Use compressed air (or nitrogen) to loosen particles on the mating plane surfaces.
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 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 device. These electrostatic effects can damage the device.
Refer to “Electrostatic Discharge” on page 3-2 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 surface dry with a gentle stream of clean, low-pressure
compressed air or nitrogen. Always completely dry the surfaces before you use it.
3. Inspect the Mating Surfaces
Inspect the mating surface to make sure that no particles or residue remain. Refer to “Visual Inspection”
on page 3-3.

Connections
Connections
Good connections require a skilled operator. Instrument sensitivity and mechanical tolerances are such that
slight errors in operator technique can have a significant effect on measurements and measurement
uncertainties. The most common cause of measurement error is bad connections.
Connecting Waveguide Devices
IMPORTANT Unlike threaded devices, the WR-28, WR-22, WR-19, WR-15, and WR-10 waveguide mating
planes are flanges (often precision) that you must carefully screw together. Always connect
port 1 of the device to port 1 of the PNA during the system verification procedure. When you
are reading the label on the device, port 1 is on the left or at the top, depending on whether
the label is oriented horizontally or vertically. See the following pictures.
Figure 3-2 Flange Example 1
Figure 3-3 Flange Example 2
The following procedures illustrate how to make good connections.

How to Connect:
R-band WR-28
Always connect the waveguide with the same flange orientation. For example, always connect a device with
the label facing the same direction.
Follow theses recommendations for optimum connection technique:
1. Place two alignment pins (with heads) in opposite holes of each flange. For example, one in the top left,
and one in the bottom right.
2. Using the pins as guides, carefully align the flanges, and insert screws in the two open corner holes.
3. Place a lock washer and nut on each screw, and finger tighten.
4. Remove the alignment pins and insert the remaining two screws.
5. Place a lock washer and nut on each screw, and finger tighten.
6. Inspect each lock washer to be sure they are similarly compressed.
7. In an X pattern (for equal compression), use the hex ball driver to tighten all four screws. Do not
over-tighten.
NOTE Apply symmetrical pressure as you gradually tighten the screws.
8. Visually inspect the connection:
a. Place an electric light or white paper behind the connection.
b. 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).
c. Inspect the washers for symmetrical compression. This ensures that all four screws are equally
torqued.
How to Connect:
Q-band WR-22
U-band WR-19
V-band WR-15
W-band WR-10
To ensure proper flange mating, each device has two attached alignment pins, and two alignment holes
through which you slide additional pins. You don’t have to use nuts or washers when connecting Q, U, V, or
W-band waveguide. The flanges have tapped screw holes; captive screws (threaded half-way up the shaft)
are provided in these kits. 

Follow these recommendation for optimum connection technique:
1. Install four captive screws into the test port.
2. Install the alignment pins.
3. Using the pins as a guide, bring the flanges together and gently engage the first few threads of each
