OPTIMIZING AND RUNNING THE
After the configuration file is loaded, the settings can be further
optimized using the
ADPD Config
window shown in Figure 7.
Typically, the device is set up under a certain set of conditions,
such as measuring the response from a fixed reflector or
measuring a PPG signal from the ear (see Figure 8). Settings
can be optimized for any set of conditions by manipulating
LED drive currents, transimpedance amplifier (TIA) gain, and
analog front end (AFE) timing. Another option is to use
different operating modes that can be more optimal for a
specific set of conditions, such as using float mode for a low
current transfer ratio (CTR). For information on optimization
of the
data sheet. For
functional descriptions of the Applications Wavetool, refer to
the Applications Wavetool user guide provided in the software
package download.
