產品規格

Item	Details / Reference	Value
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.	±1% for values greater or equal to 500μV. ±5μV for values under 500μV.
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 (see 4.2). 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
