Description
Product Introduction
⚙️ Product: ZMI-2002
🏷️ Part Number: 8020-0211
🔬 Brand: ZYGO
📐 Product Type: Dual-Axis Displacement Measurement Board
The ZYGO ZMI-2002 8020-0211 is a dual-axis measurement board from the ZMI 2000 series. It is designed for precision displacement measurement using ZYGO heterodyne interferometer systems and is built in a 6U VME form factor. The board processes interferometric reference and measurement signals and provides high-speed position, velocity, and timing data for precision motion applications.
📡 The board supports two measurement axes on a single VME board and can be integrated with servo cards or motion controllers through the P2 interface. ZYGO documentation references data rates up to 7.7 MHz for multi-axis configurations, making the platform suitable for high-speed precision positioning systems.
🏭 Typical applications include semiconductor manufacturing equipment, precision motion stages, metrology systems, optical inspection equipment, high-precision machine tools, and laboratory measurement platforms.

Installation & Use
🛠️ Before installation, verify the complete ZMI-2002 8020-0211 part number, board revision, VME chassis compatibility, interferometer configuration, and required laser/interface equipment.
🔌 Install the board in a compatible 6U VME chassis and confirm the backplane power supply meets the specified +5 VDC requirement. Handle the board using appropriate ESD precautions.
📡 Connect the reference and measurement optical signals according to the ZMI system configuration. Check fiber routing and connector cleanliness carefully, since contamination or excessive bending can affect interferometer signal quality.
📊 After startup, verify the two measurement axes, position data, velocity data, timing synchronization, and communication through the VME/P2 interface.
⚠️ This is precision metrology equipment. For replacement applications, match the exact board revision and system configuration before commissioning; do not substitute a visually similar VME measurement board without verifying electrical and optical compatibility.
