General Information
Static-safe Handling Procedures
Electrostatic discharge (ESD) can
damage or destroy electronic
components. Use a static-safe work
station to perform at work on electronic
assemblies. The figure shows a
static-safe work station using two types
of ESD protection:
-Conductive table-mat and wrist-strap
combination
-Conductive floor-mat and heel-strap
combination
Both types, when used together, provide a significant level of ESD protection. Of
the two, only the table-mat and wrist-strap combination provides adequate ESD
protection when used alone. To ensure user safety, the static-safe accessories
must provide at least 1 MΩ of isolation from ground.

Customizing an SMD Test Fixture
Create a New PC Board
The customer is responsible to design and layout a microstrip line PC board with
the contact pattern to match the device(s) being tested. A DXF CAD file for the
PC board is available at www.keysight.com/find/PD1000A. Carefully layout the
microstrip line PC board following the guidelines in the DXF CAD file. The board
must not exceed the 30 mm x 36 mm (shown below) to fit inside the SMD Test
Fixture frame. Solder pads must extend to the edges of the board to permit
soldering the frame SMA center connector pins to the PC board.
Figure 18 below shows the microstrip line PC board provided with the PD1000A
SMD Test Fixture. Yours will be different. TO-263-7 package shown for
orientation and size reference. Dimensions shown are the critical dimensions, all
dimensions are in mm. Shaded area represents copper clad on the PC board.

Important: The RF signal lines must maintain a 50 Ω impedance by
microstrip line.
Several very good web sites that provide calculations for microstrip line layout to
maintain the 50 Ω characteristic impedance. The following example presents
general guidelines.

Create the Frame Guide
The Frame Guide must be made of ESD protected, heat resistant (>100 °C)
material. Keysight recommends the standard SCM5100 ESD grade IC Test
Socket available from PBI Advanced Materials:
http://www.pbi-am.com/contents/esd/index.html?lang=EN. This material is easily
machined to size and deburred. The following diagram shows the dimensions of

Create New Calibration Standards
Along with the customized microstrip line PC Board and Frame Guide, you will
need to create seven new Calibration Standards. These Cal Standards are small
microstrip line PC boards with Open, Short, and Through; two boards have 50 Ω
SMD resistors. The dimensions of the seven new Cal Standards must be the
same as the outside dimensions of your DUT; the thickness of the Cal Standard
must be the same thickness as your DUT. The seven PC boards must be designed
as follows (use the provided TO-263-7 Cal Standards as examples):
Cal StandardConnection Requirements
Port 1 OpenNo connection, Gate to Source/Emitter.
Port 1 ShortDirect connection, Gate to Source/Emitter.
Port 1 50 Ω LoadGate to Source/Emitter. Use a 50 Ω SMD resistor. The resistor must go on
the top side of the PC board, not the trace side. See Figure 21 below.
Port 2 OpenNo connection, Drain/Collector to Source/Emitter.
Port 2 ShortDirect connection, Drain/Collector to Source/Emitter.
Port 2 50 Ω LoadDrain/Collector to Source/Emitter. Use a 50 Ω SMD resistor. The resistor
must go on the top side of the PC board, not the trace side. See Figure 21.

Troubleshooting
This section provides a simple functional verification procedure to test the
PD1000A Test Fixtures, cables, and Calibration Standards. This test procedures
do not verify the resistance accuracy of the Calibration Standards.
SMA Cables
Do not excessively bend, flex, or stretch the SMA cables. Check the SMA cables
regularly, and replace them if they are damaged in any way. It is possible for the
outside shielding of the cables to break.
Figure 25Damaged SMA Cable
Measuring the DC Resistance of the Calibration Standards
A simple verification test for the Calibration Standards is to measure the DC
resistance of the standards. To the TO-220 and TO-247.
Measure the resistance between the two Cal. Standard pins or SMD pads. As
shown below, the Calibration Standards should measure open (infinite
resistance), short (0 Ω), 50 Ω, and pass-through (Gate to Drain/Collector).

Use Proper SMA Connector Care and Connection Techniques
Use Proper SMA Connector Care and Connection Techniques
Good connections are essential for accurate calibrations and measurements and
require a skilled operator. The most common cause of measurement error is poor
connections.
SMA connectors will mate with 2.92 and 3.5 mm connectors. However, a
damaged SMA connector, or a used SMA connector with a slightly bent pin can
destroy a 2.92 or 3.5 mm connector. In SMA connectors, the center pin connects
first, before the threads. If an SMA pin is bent or off-center for any reason, then
the pin will make contact with the 2.92/3.5 mm female contacts which are
unsupported as an air dielectric is used, and the female contact may be pushed
out of place.
1 Ground yourself and all devices. Wear a grounded wrist strap and work on a
grounded, conductive table mat.
2 Visually inspect the connectors. If necessary, clean the connectors.
3 Carefully align the connectors. As you make the actual connection, be sure
the connectors align perfectly.
4 Push the connectors straight together. Do not twist or screw the connectors
together.
5 Engage the connector nut (of the connector with the retracted sleeve) over
the threads of the other connector (the connector with the extended sleeve).
Turn only the connector nut. Let the connector nut pull the two connectors
straight together.
6 Do not over tighten this connection. A connection in which the outer
conductors make gentle contact at all points on both mating surfaces is
sufficient. Very light finger pressure is enough to accomplish this.
7 Make sure the connectors are properly supported. Relieve any side pressure
on the connection from long or heavy devices or cables.
8 Torque the connection according to the procedures described below.

Final Connection Using a Torque Wrench
Using a torque wrench guarantees the connection is not too tight, preventing
possible connector damage. It also guarantees that all connections are equally
tight. Prevent the rotation of anything other than the connector nut that you are
tightening.
Use a Keysight 8710-1582, 0.56N-m (5 lb-in) 5/16 inch break-over torque
wrench to make a final connection. A Torque wrench is supplied as part of the
PD1000A-SPK Accessory Kit.
.
Figure 7Keysight 8710-1582 SMA Torque Wrench
The Keysight 8710-1582, 5 lb-in Torque Wrench is a precision
instrument and should be treated and maintained like a measuring
instrument.
1 Turn the connector nut. This may be possible to do by hand if one of the
connectors is fixed (as on a test port). However, it is recommended that you
use a second open-end wrench to keep the body of the device from turning.
2 Position both wrenches within 90 degrees of each other before applying force.
Wrenches opposing each other (greater than 90 degrees apart) will cause a
lifting action that can misalign and stress the connections of the device
involved. This is especially true when several devices are connected together.
Refer to the following figure.
Figure 8Wrench Positions

Torquing Direction
Stop when handle begins to yield
3 Hold the torque wrench lightly, at the end of the handle only (beyond the
groove). See the following figure.
Figure 9Using the Torque Wrench
4 Apply force downward to the wrench handle. This applies torque to the
connection through the wrench. Do not hold the wrench so tightly that you
push the handle straight down along its length rather than pivoting it,
otherwise you apply an unknown amount of torque.
You don’t have to fully break the handle of the torque wrench to
reach the specified torque; doing so can cause the handle to kick
back and loosen the connection. Any give at all in the handle is
sufficient torque.
5 Tighten the connection just to the torque wrench break point. The wrench
handle gives way at its internal pivot point. Do not tighten the connection
further.
Separating Connections
To avoid lateral (bending) force on the connector mating plane surfaces, always
support the devices and connections.
Do not turn the device body. Only turn the connector nut. Damage
to the center conductor can occur if the device body is twisted.
1 Use an open-end wrench or spanner wrench to prevent the device body from
turning.
Keysight PD1000A Power Device Measurement System23
2 Use another open-end wrench or the torque wrench to loosen the connector
nut.
3 Complete the separation by hand, turning only the connector nut.
4 Pull the connectors straight apart without twisting, rocking, or bending.
Inspect and Clean Connectors
Clean connector interfaces prolong connector life and produce more accurate
and repeatable measurements. When using SMA female connectors, pay special
attention to the contact fingers on the female center conductor. These can be
bent or broken, and damage to them is not always easy to see. A connector with
damaged contact fingers will not make good electrical contact and must be
repaired or replaced.
Inspect each connector to make sure that no particles or residue are present.
Connector Cleaning
Always use protective eye-wear when using compressed air or
nitrogen.
Keep isopropyl alcohol away from heat, sparks, and flame.
Store in a tightly closed container. Isopropyl alcohol is
extremely flammable. In case of fire, use alcohol foam, dry
chemical, or carbon dioxide; water may be ineffective.
Use Proper SMA Connector Care and Connection Techniques
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
regulation.
– Use compressed air to loosen particles on the connector mating plane
surfaces.
– Apply a small amount of isopropyl alcohol to a lint-free swab. Clean the
connector threads. Let the alcohol evaporate, then blow the threads dry
with a gentle stream of clean, low-pressure compressed air or nitrogen.
Always completely dry a connector before you reassemble or use it.
