Spider 80M MIMO Vibration Controller

• Based on Spider-80Xi Architecture
  The Spider-80M platform is based on the efficient Spider-80Xi architecture and is dedicated to MIMO VCS control and MIMO structural testing applications. Each Spider-80M chassis features 8 outputs capable of carrying out 6-degree of freedom MIMO testing. One Spider-80M chassis and multiple Spider-80Xi chassis can chain together to form a very large system with up to 504 input channels.
• Expand Channel Count
  In a Spider-80M hardware chassis a master module with 8-inputs and 8-outputs will always be installed. This master module takes the space of two slots of Spider-80Xi module in the S80M-A35-8N chassis. Up to 6 additional Spider-80Xi front-end modules can be inserted to form a system with 8 outputs and up to 56 inputs.

  The Spider-80M chassis can combine with multiple Spider-80Xi chassis to form a system with up to 504 input channels, all sampled simultaneously. Accurate time synchronization results in excellent phase match in the frequency domain between all channels, either on the same Spider front-end or across different front-ends. Channel phase match, even between separate Spider front-ends, is within 1.0 degree at 20 kHz which is suitable for high quality structural and acoustics applications requiring cross channel measurement.

• Mass Storage
  A high-performance removable 2.5-inch solid-state drive is used as storage media. When recorded, data will be written in the NTFS file format. Data is extracted from the Spider-NAS using Crystal Instruments software to transfer data to the PC. Alternatively, the solid-state drive can be physically removed and connected to extract data to the PC.

  When it is shipped, a 250 GB solid-state drive is installed internally. The solid-state drive performs very well in the high shock and vibration environment. A special error-checking algorithm developed by Crystal Instruments detects and avoids any errors that may occur in the data transfer and storage.

• Time Synchronization
  Through the Ethernet connection, multiple Spider-80Xi or Spider-80M chassis can be synchronized through the IEEE 1588v2 protocol. The synchronization accuracy is within nanoseconds when a specified network switch is used. The data acquired by all the measurement channels will be on the same time base. Phase match between channels across different Spider front-ends is within nanoseconds.

EDM software is a complete VCS (Vibration Control System). Crystal Instruments has recently released the new EDM 9.0 release, the most powerful and feature rich version of EDM software. EDM 9.0 release supports the newly introduced hardware units (Spider-80Hi, Spider-80Ci, Spider-20i, Spider-20H, Spider-20HE) that support data acquisition and recording for up to 256 kHz. In addition, the proprietary Multi-Resolution technology has been extended to benefit frequently used Vibration Control tests for Single-axis and MIMO tests. EDM has the following suite of software modules:
