Doric NC500 Neuroscience Acquisition Host

Product Overview

Product positioning: Multi functional integrated scientific research acquisition hardware, which improves the number of channels, sampling rate, and sampling accuracy compared to the previous generation fiber optic photometric host. It can synchronously collect multimodal experimental data in parallel and achieve closed-loop linkage of optoelectronic physiology, microscopy, light stimulation, and behavioral equipment.

Core experimental functions

Multi color multi-point fiber optic photometry: built-in phase-locked and time-division sampling algorithms, high-precision fluorescence signal acquisition;

Third generation micro fluorescence microscope signal acquisition;

Digitized recording of in vivo electrophysiological head end signals;

TTL digital IO realizes synchronous closed-loop control of optical genetic light source, behavioral box, camera, and trajectory tracking equipment;

Manually mark experimental behavior events with panel buttons.

Hardware key electrical specifications

1 IO channel parameters

Project parameters

The total number of digital channels is 32 (with 24 branches from 8BNC+DB25)

Digital maximum sampling 50kSps, DO maximum output 20kHz

Analog output: 8-channel BNC, 0~5V, 16 bit, up to 10kHz

Analog input: 8-channel BNC, ± 10V, 18 bit, up to 50kSps

2 Analog inputs (chopper noise reduction mode)

The device defaults to chopper noise reduction to reduce zero drift and noise. The lower the sampling rate, the higher the effective resolution: 0.3kSps can achieve a 20 bit effective resolution and noise of 9.6 μ V; The higher the speed, the greater the noise and the lower the effective number of bits.

3 Minimum Computer Configuration

Win10 64 bit system, CPU 3GHz eight core, ≥ 8GB memory (recommended 16GB), hard disk reserved 500MB space, preferred SSD, USB3.0 communication.

4 Mechanical dimensions: 115 × 50 × 400mm

Environmental Usage Standards

Work: 0~40 ℃, humidity 40%~60% RH, no condensation, indoor use only;

Storage: Same temperature and humidity standards.
