| 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 12leads. | 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 |
| 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 |
