Overview
- Integrates IEC 60601-2-47 test items*, including dynamic range, input impedance, frequency response, etc.
- Equipped with 4 sets of electrode terminals － RA/LA/RLD electrode terminals on each set to meet testing needs for wearable device's ECG function
- Outputs 7 types of standard ECG waveforms － ECG Waveform, Sine, Triangle, Square, Exponential, Rectangle Pulse, and Triangle Pulse
- Provides SDK － users can flexibly develop automated testing programs and control multiple WECG400 to test more than 4 DUTs simultaneously
- Supports sequential testing － tests DUTs one at a time according to a user-defined sequence
- Equipped with 4 DUT Monitor ports to connect to an oscilloscope － amplifies the ECG signals to help users monitor the signal output with higher resolutions
- Rack-mountable and easy to deploy with the 1U height design
*Note: For the two test items as system noise and common mode rejection, please refer to the CMRR 3.0+ Common Mode Rejection Ratio Tester for testing.
Testing Scenario - Single WECG400
