MECG 2.0 multi-channel ECG waveforms

Compliant with IEC 60601-2-25, IEC 60601-2-47, ANSI / AAMI EC57, YY0782 and YY0885.

• Load and replay multi-channel ECG waveforms for diagnostic and ambulatory ECG

• Output analog signals simultaneously up to 8 channels and support 12 lead ECG

• Embedded CAL, ANE, NST and biological waveforms

• Directly support AHA, MIT, CU, NST, ESC and PhysioNet format databases

• Support digital file playback function for user to repeatedly play clinical-recorded or programmed waveforms

• Extreme output voltage resolution - 0.15μV for MECG 2.0 (2020)

• Command replay function enables to program test sequences with commands

• Software Development Kit (SDK) allows to develop customized or automated test software with less efforts.

• Items	Details / Reference	Values
  Output channels	The 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 lead 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.	For MECG 2.0, ±1% for values greater or equal to 500μV and ±5μV for values under 500μV. For 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 normal laboratory environment. The selection of critical components such as reference voltages, DAC, precision resistors are known to be stable in the range shown.	15 - 30°C 10 - 95% RH
