The requirement is for an iWorx-compatible physiological data acquisition system with a minimum 18-channel recorder expandable to at least 34 total channels and the ability to gang multiple recorders for expanded acquisition. It must include wireless ECG/EMG and 3-axis accelerometer capability with expansion to 16 wired channels, two built-in ±15 V low-voltage inputs, an isolated constant-current high-voltage stimulator, at least 16 digital I/O channels, and at least one audio output. Integrated measurement features include pulse oximetry, spirometry, grip force and intensity sensors, pre-calibrated temperature/force/spirometry/blood pressure sensors, an ECG simulator, and a barometric pressure sensor to improve spirometry accuracy without external hardware. The unit must be portable, operate via USB-C power, and support iWire compatibility for future sensor and instrumentation expansion. It also must include lifetime free LabScribe software updates, an open site license, and unlimited online training at no additional cost.
