Short Specs

Item	Details	Value
Output Channels	8 output channels are provided through a network as specified in IEC 60601-2-51 to provide signals to 10 lead electrodes; in the device under test, this will be displayed as 12 leads	8 outputs 10 leads electrodes 12 leads
Voltage Accuracy	IEC 60601-2-51 specifies a limit of ±1%, but does not provide a lower limit (all systems must have a lower limit). An inferred specification of 1% ±5µV is derived from the device under test specification in IEC 60601-2-51 of 5% ±25µV	– MECG 2.0, ±1% for values greater or equal to 500μV and ±5μV for values under 500μV – MECG 2.0 (2020), ±1% for values greater or equal to 100μV. ±5μV for values under 100μV
Output voltage resolution	MECG 2.0 uses 12 bit DAC and MECG 2.0 (2020) uses 16 bit DAC	MECG 2.0 for 2.4μV and MECG 2.0 (2020) for 0.15μV
Output Voltage	The output voltage on most of the database and ECG is +5mV~-5mV.	±5mV
Output Noise Level 0-150Hz	Output noise should not influence the test. A value a 5µV is suitable for this requirement. Can be verified by monitoring the signal in the device under test using a “diagnostic” filter setting	<5µV
Time Accuracy	IEC 60601-2-51 does not provide any limits. An inferred limit from the device under test. An inferred limit of ±1% is used. The system’s design accuracy exceeds 0.1% as a 100ppm crystal reference is used	±1%
Sampling Rate	A maximum sampling rate of 1kHz matches the sampling rates of ECG files	1kHz (8 channels)
Power Supply	Powered from the USB supply (5V 0.2A)	N/A
Environment	Intended for laboratory environment. The selection of critical components such as reference voltages, DAC, and precision resistors are known to be stable in the range shown	15-30°C 10-95% RH
