PPG Heart Rate Simulator Test System | User Manual
System Introduction
WhaleTeq Heart Rate Simulator (HRS) is a test system designed for
“Photoplethysmography” (PPG) technology. For PPG sensor suppliers, IC Solution
providers, and wearable manufacturers, HRS simulates the reflected light of human
skin, and provides different adjustable parameters such as brightness, heart rate, and
so on.
1.1 Basic Concept
1.1.1 Photoplethysmography (PPG)
This technology captures blood information via optical signal. Most Pulse
Oximeter (SpO2) equipment on market now use PPG technology. In the recent
years, wearable devices are becoming increasingly popular and most
manufacturers and brand companies use PPG technology as the key
technology to capture heart rate value.
The theory behind this technology: By shining LED light to the skin and while
the light would be partially absorbed by the skin and reflected (or refracted)
back to photodiode, the system can then collect and calculate the value
differences into heart rate (BPM).
1.1.2 Perfusion Index (PI)
Following the description stated in section 1.1.1, the below diagram can be
explained as X axis representing for the time while Y axis representing the light
reflection received by photodiode.
As shown in the above diagram, there are slight signal fluctuations (AC, refers
to Heart rate signal) above the carrier signal (DC) and the ratio of AC to DC is
defined as Perfusion Index (PI).
Remark: PI value can be adjusted, but the value range would be varied due to
the changes of DC value. See upper-right figure.

1.1.3 WhaleTeq Heart Rate Simulator Test System
WhaleTeq HRS test system is based on the concept described in section 1.1.1
and 1.1.2. The simulated light source provided by the system verify if the
photodiode of the wearables can receive the LED light properly, and if the
module can react well with different simulated light. Meanwhile, the test
system has built-in photodiode as well. Users can use the built-in photodiode
to verify the light source of different wearables.
On top of simulation of heart rate signals, users can also adjust parameters to
simulate reflection of different brightness levels (DC), conditions of peripheral
circulation (PI). The WhaleTeq HRS test system provides various settings and
multiple operation modes for different PPG sensors and different scenarios.
WhaleTeq HRS test system has 2 different models –HRS200 and HRS100+.
-HRS200：
Premium Model. Designed for R&D and test engineers to provide multiple
and stable signal simulations to facilitate the verification of system and
heart rate accuracy.
-HRS100+：
Advanced Model. Designed for test engineers and production line
application. This model can quickly measure DUT’s PD and LED.
Furthermore, this test system can conduct heart rate test procedure and
quickly sort out defective LED.
This document is mainly for HRS200 and you may contact WhaleTeq at
[email protected] for details of HRS100+.
1.1.4 How HRS interacts with DUT
In order to accurately simulate heart rate, HRS test system has built-in LED
and PD, which are individually corresponding to the wearable’s PD and LED.
Please note that LED and PD shown in HRS PC software from the view of
HRS. For example, PD sampling (section 3.2.1) shown in HRS PC software
indicates DUT’s LED status.
