# Introduction

The PXIe-9908 is a high-density SMU module designed for automated testing and mini/micro LED wafer probing applications. It supports precision sourcing and measurement up to ±100V and 100mA, with scalable configurations. With compatibility across major operating systems and programming languages, it delivers fast, accurate, and reliable testing performance tailored for automated test systems and next-generation display technologies.

# Ordering Information

# Source and Measurement Unit

• PXIe-9908
8-ch 4-quadrant Source Measurement Unit (SMU)

# Terminal Boards & Cables

• TB-6221\*1
Termination Board with 62-pin D-Sub Connector (cables not included)

• ACL-10262\*1

D-Sub 62 Pin (Male) to D-Sub 62 Pin (Female), 1M

\*1 Using TB-6221 and ACL-10262 will cause unstable output and measurement when operating under low current range (below 2mA). If operation under such a low current range is required, it is recommended to design dedicated cables and connection boards.

# Software Support

• Operating System Support
Windows 10/11 x86/x64 or later
• Driver and SDK
C/C++, C#, LabVIEW

# Specifications

• Specifications are valid under the following conditions unless otherwise noted.

• Ambient temperature of 25°C ± 5°C
• Calibration interval of 1 year
• 30-minute warm-up time
• Fans set to the highest setting when the PXI Express chassis has multiple fan speed settings
