Spider - Model 80M MIMO -Vibration Test Controller

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 drive can be upgraded up to 2 TB. 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.
