After the configuration file is loaded, the settings can be further
optimized using the ADPD Config window shown in Figure 11.
Typically, the device is set up under some set of conditions,
for example, measuring the response from a fixed reflector or
measuring a PPG signal from the wrist (see Figure 12). Settings
can be optimized for any set of conditions by manipulating LED
drive currents, transimpedance amplifier (TIA) gain, and

analog front end (AFE) timing or by using different operating
modes that may be more optimal for a specific set of conditions,
for example, using float mode for very low current transfer ratio
(CTR). For information on optimization of the ADPD188GG,
refer to the ADPD188GG data sheet. For functional descriptions of
the Applications Wavetool, refer to the Applications Wavetool user
guide that is provided in the software package download.
