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.

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 Standard Connection Requirements
Port 1 Open No connection, Gate to Source/Emitter.
Port 1 Short Direct connection, Gate to Source/Emitter.
Port 1 50 Ω Load Gate 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 Open No connection, Drain/Collector to Source/Emitter.
Port 2 Short Direct connection, Drain/Collector to Source/Emitter.
Port 2 50 Ω Load Drain/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 25 Damaged 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 7 Keysight 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 8 Wrench Positions
22 Keysight PD1000A Power Device Measurement System
Use Proper SMA Connector Care and Connection Techniques
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 9 Using 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 System 23
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.
