Welded DIN1.5 1-64Hz Brain Wave EEG Development Signal Generator Toggle Switch Version for EEG Development and Calibration
Description:
- EEGCAL EEG signal generator, suitable for use in the development and calibration of EEG equipment.
- Equipped with lithium battery and charging circuit, more convenient to use.
- It can generate single point sine signals (corresponding to the steady-state response of the channel), sweep signals (corresponding to the frequency response of the channel), and pulse signals (corresponding to the pulse response of the channel). The frequency and amplitude of the generated signals are consistent with EEG, making it suitable for use in EEG equipment development or calibration. Especially for EEG acquisition devices that use ADS1299 as AFE, this signal generator has been specially optimized and tested to support differential testing under various modes such as SRB1 as a public reference, SRB2 as a public reference, BIAS common mode negative feedback, etc.
- It can generate single point sine signals ranging from 1 to 64Hz, with output amplitudes of 2000uV, 200u, and 50uV.
- It can generate sweep frequency signals ranging from 1 to 64Hz, and multiple sweep frequency parameters can be set.
- It can generate pulse signals, and the pulse width and repetition frequency can be set.
- Equipped with battery level detection.
Test 1-ADS1299 Acquisition Test:
- Set the signal generator to single point sine mode and connect it to channel 1 of the ADS1299 acquisition board, as shown in the following figure:
- The driver program for the acquisition server under OpenViBE has been designed for the EEG acquisition board. Connect the acquisition server to the acquisition board, create the following scenario in OpenViBE Designer, and then start acquisition, as shown in the following figure:
- After starting the acquisition, the obtained results are shown below, and the correct results were observed in channel 1.
