Start Button

When the Start button is pressed, the CDB5461AU will capture pulse rate data according to the values in the Inte-
gration Seconds
and Periods to Average fields. After each integration period, the Pulse Count and Frequency col-
umns will be updated. The Average Freq. and Standard Deviation columns will only be updated after all the
integrations have been collected. The software stops collecting data when the user presses the Stop button, or when
the data collection is complete. Due to speed limitations of the on-board microcontroller, some higher pulse rates
cannot be accurately collected.

the CS5461A and analyze them using time domain, FFT, and histogram plots. The Data Collection window is ac-
cessible through the Menu pull-down, or by pressing .
