Spectrum M2i.7021-Exp High-Speed Digital I/O Card | 125 MS/s 64-Channel Pattern Generator (M2p.7515-x4 Compatible)

 Technical Reference & Availability: Spectrum Instrumentation M2i.7021-Exp High-Speed Digital I/O

The Spectrum M2i.7021-Exp is a high-performance PCIe-based digital waveform acquisition and pattern generator card. Designed for demanding automated test environments (ATE), it features 64 independent TTL channels and a maximum sampling rate of 125 MS/s. This module is an essential tool for engineers requiring precise digital sequence generation or high-speed logic analysis, often cited as a reliable predecessor or companion to the M2p.7515-x4 series.

Core Technical Specifications

  • Channels: 64 Input or Output channels (TTL levels).

  • Sampling Rate: Up to 125 MS/s (Mega-samples per second).

  • Onboard Memory: Massive 1 GByte buffer for long-duration waveform storage.

  • Bus Interface: PCI Express (PCIe) x1.

  • Modes of Operation: Supports FIFO Mode for continuous data streaming to PC memory or hard drives.

  • Triggering: Advanced pattern, edge, and pulse width triggering, including gated sampling.

  • Synchronization: Compatible with the internal synchronization bus for multi-card arrays (M2i.70xx series).

Advanced Capabilities

The M2i.7021-Exp is optimized for flexibility, allowing resolutions from 1-bit to 64-bit. Its ability to run in FIFO mode makes it ideal for real-time digital communication analysis and large-scale data logging where data gaps are not acceptable.
