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

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
