A stand-alone apparatus is provided for acquiring analog signals of noise, vibration, temperature, pressure or the like and processing the acquired signals. The apparatus includes an input module, a processing module, an interface, a data logging memory and a power supply module. The input module is connected to sensors. The processing module has an amplifier, a filter, an AD converter, a DSP, an FPGA (Field Programmable Gate Array) and a microprocessor unit with a RTOS (real time operating system). The interface connects the apparatus with a computer. |
