This FPGA-based data acquisition unit synchronizes the output control and the input data acquisition. It seamlessly integrates with Doric Neuroscience Studio that provides a user interface for multi-channel photometry experiments. The software interface enables control over the CW pulsed excitation light, or sinusoidal waveform trig of an external source (i.e., LED driver) with 4 TTL and 4 analog voltage outputs. The software interface displays real-time recording data of up to 4 detector input signals. Signal processing does basic arithmetic functions between two channels, filter function to remove unwanted frequencies from the data, calculates ΔF/F, etc. New functionalities are being continuously added.

• 4 Digital Input/Output TTL to sync with other devices
• 4 Analog Inputs to record multiple data stream (i.e., detectors)
• 4 Analog Outputs to control other devices (i.e., LED driver)
• Real-time lock-in amplification, filters, and interleave demodulation
• USB2 connection to a computer, cable included
• Controlled by Doric Neuroscience Studio with photometry-oriented interface
• Frequent and free software updates
