AECG100 | User Manual
Product Introduction
WhaleTeq’s AECG100 is a multifunction testing unit, which could
function as ECG (Electrocardiogram) tester, PPG (Photoplethysmography)
tester, PWTT (Pulse Wave Transit Time) tester, and SpO2(Peripheral
Oxyhemoglobin Saturation) tester parameter adjustment control. The
main ECG module is a single-lead ECG tester that could produce signals
according to IEC standards for medical equipment. The users can use it
with the single-channel or dual-channel PPG module of their choice. The
single-channel PPG module provides a green LED, offering simulated PPG
heart rate signals; besides, the dual-channel PPG module provides red
LED and infrared LED, simulating different Sp02blood oxygen levels.
When the ECG module and the PPG module work at the same time, the
users can get the pulse wave transit time (PWTT) by adjusting the time
difference (PTTp or PTTf) between the peak value of ECG to the peak or
the valley of the PPG wave. The parameters can be used for improving
the wearable devices on measuring blood pressure and calculating the
degree of arteriosclerosis. This method can significantly increase the
accuracy of the blood pressure measurement.

2.4 DUT Best Position Adjustment
2.4.1 Reflective SpO2Testing Device
Figure 13: Reflective PPG-1R-525 Module (as example)
Step 1: Line up the DUT’s LED with the PD of AECG100.
Step 2:Confirm the position of the DUT’s LED and AECG100’s PD
are lined up: Connect AECG100 to the computer and power
on AECG100. Download, install and execute the AECG100
software on the computer, and see if the pulse signals are
visible on the PD’s sampling tab. If so, the LED of the DUT is
lined up with AECG100’s PD.
Step 3: Confirm the positions of the DUT’s PD and AECG100’s LED:
Execute the AECG100 software, and under PPG test mode,
set DC=500mV AC=30mV BPM=60, and check if DUT can get
the heart rate of 60 BPM.
。If so, then the relative positions of DUT’s PD and
AECG100’s LED are correct.
。If not, try to modify the DC value by adding or
reducing 50mV and check again to see if DUT can get
the heart rate of 60. If the heart rate is still not found,

19
AECG100 | User Manual
reposition DUT and repeat Step 2 and Step 3 until
DUT can get the heart rate.
2.4.2 Transmission SpO2Testing Device
Figure 14: Transmission SpO2Module (PPG-2TF-660)
Step 1: Clamp the DUT to the index finger simulation on the PPG-2TF-
660, and plug the DB15 connector on the PPG-2TF-660 into the
DB15 port on the AECG100 main console. Plug the USB Type-B
connectors of the USB cables provided to the AUX PWR port and
USB port on the AECG100 main console; at the other end of the
USB cables, plug the USB Type-A connectors into a laptop or a PC.
Switch the power switch located at the lower-left corner on the top
of the AECG100 main console to ‘’On’’ to power on it.
Note: Align the LED and PD on DUT to the PD and LED on the PPG-
2TF-660 respectively.
Step 2: Go to the official AECG100 webpage to download and install the
AECG100 software. Complete the installation and click the AECG
icon to start the test. Select the Auto Test SpO2tab and check the
"signal strength" on the software interface. It shows the optical
signal intensity detected.

Note:
Because the light intensity of the DUT varies, the "signal strength" may not
be filled. Please adjust the position and find a relatively large signal value.
2.5 Operation Modes
AECG100 can be controlled through PC software operation or
standalone operation.
2.5.1 PC Software Operation
AECG100 must be connected to the computer and the PC
software should be installed properly. AECG100 offers a total
of 4 test modes, including ECG test mode, PPG test mode,
PWTT test mode, and SpO2test mode. Auto Sequence test
mode can combine any of the 4. Please see chapter 4 Software
Interface for a detailed operation description.
ECG test mode: AECG100 can conduct single-lead ECG testing
under this test mode. All the ECG-related standards are
supported including a series of single-channel testing, such as
sensitivity, frequency response, input impedance, and so on.
This test mode is compliant with international standards of YY-
0885 and IEC 60601-2-47.
