Initial Setup of the AECG100 Tester
5.1.1.
Calibration of Opto-mechanical Test Fixture
This test calibrates the optical parameters of the test fixture and ensures that the DUT receives sufficient signal
to continue with this test. To assure a consistent reference, this step is performed with the OB1203SD-RL-EVK
reference board as described in the previous steps.
5.1.1.1.
WhaleTeq AECG100 Setup
1. Set the AECG100 SpO2 settings to the following parameters in the GUI.
Figure 12. WhaleTeq AECG100 GUI Screenshot for Initial Test Fixture Setup
■
In the Sp02 Tab:
●
In the RED Parameter block:
○
Check Lock DC box
○
Red AC of 18.70 mV
○
Red DC of 2000 mV
■
In the IR Parameter block:
○
Check Lock DC box
○
IR AC of 15.00 mV
○
IR DC of 1000 mV
For this test, all other settings can be left to default.
2. Push “Play” and observe the IR and Red ADC counts on the calibration reference devices’ OLED display
running the OB1203 calibration software.
Adjust the IR DC and Red DC values in the WhaleTeq GUI so that the DUT Display reads 60.000 (counts)
for IR and 40.000 (counts) for Red.
