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. Keysight PD1000A Test Fixture Operating Guide... -
Page 12: General Test Setup
General Test Setup General Test Setup Figure 1 below shows the general test setup for the three PD1000A Test Fixtures (the Surface Mount Device (SMD) fixture is shown in the photo). Note the two PD1000A Bias T networks attached to the test fixture, the E5080A ENA Network Analyzer behind the test fixture, and the B2902A Precision SMU (on top of the E2080A ENA) providing bias voltage to the two Bias T networks. - Page 13 General Test Setup Use with PD1000A Bias T Networks Two Bias T devices are provided with the PD1000A Accessory Kit. Figure 2 shows the two PD1000A Bias T Networks ready to connect to a PD1000A TO-220 or TO-247 Test Fixture. Figure 3 shows the Surface Mount Device (SMD) Test Fixture.
- Page 14 B2902A Source Measure Unit (SMU). Channel 1 on the SMU (front panel) connects to the PD1000A Bias T for the RF input (Gate) to the device under test (DUT). Channel 2 on the SMU (rear panel) connects to the PD1000A Bias T for the RF output (drain or collector) of the DUT.

PD1000A Surface Mount Device Test Fixture PD1000A Surface Mount Device Test Fixture Keysight’s PD1000A SMD Test Fixture is designed for testing surface mount device packages such as the 7-pin TO-263 (also known as D PAK or DDPAK) SMD devices. Other SMD devices may also be tested with the SMD Test Fixture. - Page 18 PD1000A Surface Mount Device Test Fixture When finished testing a device, lift up on the Test Fixture handle and carefully remove the DUT. If your SMD device does not have the pin-out shown below, or if your device has different dimensions than the standard device, you will need to create a custom frame and PC Board.

Page 21: Fixture Calibration Procedure
Test Fixture Calibration Fixture Calibration Procedure The PD1000A Test Fixtures were developed to test semiconductor devices with standard device packaging. Each fixture type has its own Calibration Standards kit. Calibration procedures for the PD1000A Test Fixtures are the same. Use the appropriate mechanical calibration standard devices supplied with your test fixture. - Page 22 The two Calibration Kit files (TO_Fixture_In.xkt for the Input Port and the TO_Fixture_*.xkt for the Output Port) are available from www.keysight.com/find/PD1000A. If you have not already done so, download these files directly to the E5080A hard drive (if it has an Internet connection) or onto a USB memory stick.
