技术说明
The Spectrum 103 (three channels) and 109 (nine channels) share the same design, offering a variety of selectable input ranges on each channel.
Synchronization
Channels are digitized using a 32-bit ADC and offer channel-to-channel sampling synchronization within approximately ±10 ns.
When using the EPI bus for synchronization across multiple modules, module-to-module synchronization is achieved within approximately ±100 ns.
Three-Axis
Each Spectrum channel offers selectable input ranges: ±200 mV, ±1 V, ±5 V, and ±10 V. The Spectrum 103 and 109, providing three or nine input channels respectively, make them ideal for three-axis accelerometers and strain gages.
Connection via EPI and CPI
Spectrum modules connect to data loggers via EPI or CPI networks using standard Ethernet cables (CAT5e, CAT6, or higher). EPI networks are ideal for Spectrum applications. For smaller channel count setups, a single Spectrum is connected to a traditional CPI-enabled data logger, such as the CR6 or CR1000X.
Basic Programming
Short Cut software streamlines basic program creation for reading multiple Spectrum modules. It generates a wiring diagram and a CRBasic program for your data logger. For advanced processing or data management, you can further customize the CRBasic program.
Sample Rate
Program an anti-aliasing filter for sample rates up to 10 kHz and bandwidths up to 5 kHz.
