Overview
The technology described in this article was successfully used in the Ground Recorder System to achieve a very high measurement of dynamic range for a recent NASA project. This technology is now integrated into the CoCo-80X portable hardware platform by Crystal Instruments.
Sampling Synchronization Through GPS Signals
Crystal Instruments has recently been granted a patent (US 11,611,946) for the methodology used to synchronize signals acquired using multiple physically unconnected data acquisition systems.

Featuring the highest sampling rate provided in the industry at 256 kHz. Handheld battery powered system with wired & wireless network options and 20V input range. Sync between multiple devices. Choose the convenient portable model or industrial model for permanent mounting.
The Spider-20H, Spider-20HE, and Spider-20i received a hardware upgrade to support an impressive 256 kHz samping rate on all 4 input channels. It is the highest sampling rate offered in the market of compact analyzers. The high sampling rate is especially beneficial for measuring high orders and transient capture in blast tests, pyroshock events, drop shock tests, crash tests, etc.
In addition to the high samping rate, the input range is expanded to 20V to capture larger signals.

Crystal Instruments EDM 9.0 release introduces new additions to the Spider product line featuring support for sampling rates up to 256 kHz.
The new Spider-80Hi and Spider-80Ci are scalable versions of the Spider system featuring the impressive new 256 kHz sampling rate. Recording can also be performed at sampling rates up to 256 kHz for all input channels, up to 512 channels per Spider system.
The compact, ultra-portable four channel version of the Spider has also been developed to support a 256 kHz sampling rate. Currently, three variations of the compact Spiders supporting the 256 kHz sampling rate are available: Spider-20H, Spider-20HE, Spider-20i.

When designing and testing materials and products it is essential to understand its material properties and how it reacts to the forces and loads applied to it. The deformation a DUT experiences when a force is applied is called strain. Strain is the ratio of the change in length of a material to the original length. Strain can be positive (tensile) or negative (compressive).

EDM’s Account Management program controls the accessibility of features from different users. This provides a structure for managing the privileges for different groups of users. The Account Manager can be used to prevent lower-level users from adjusting parameters or display settings. It also allows users to customize the toolbars for a simplified user interface. By hiding certain features, the UI can be made much easier to use.

The Spider-80Xi platform gives users the immense flexibility to combine the Spider-80Xi, Spider-80SGi or Spider-80Ti devices into one system with synchronized data acquisition. The Spider-80SG and Spider-80SGi can work as general-purpose data acquisition systems that not only supports strain measurement but also supports several sensor types requiring precision excitation voltage, including MEMS and strain gage based sensors. The Spider-80Ti on the other hand can acquire temperature data along with any other type of measurement quantity by using it with any combination of Spider-80Xs and Spider-80SGs.
