The Spectrum Spectral Analysis and High-Speed Input Module—available in three-channel or nine-channel variants—offers high-speed synchronous sampling for analog inputs, with dedicated analog input hardware that includes amplifiers, filters, and analog-to-digital converters (ADC). Benefits and Features - Synchronization across multiple modules - Ideal for three-axis accelerometers and strain gages - Connection to data logger via EPI and CPI - Streamlined creation of basic programs - Sample rate up to 10 kHz Technical Description 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.
