2.7
The CS5463 features a pulse-rate energy output. The CDB5463U has the capability to demonstrate the
functionality of this output in the Pulse Rate Output Window. See Figure 11. The Pulse Rate Output Win-
dow can be accessed by pressing <F5>, or by pulling down the Menu menu, and selecting the Pulse Rate
Window item.
2.7.1
This field allows the user to select the length of time over which pulses will be collected. Because there is
a time delay (2x N / OWR) from start conversion to pulse output, the Integration Seconds field is normally
set to a delay longer than the actual pulsing period.
2.7.2
This field allows the user to average a number of integration periods.
2.7.3
When the Start button is pressed, the CDB5463U will capture pulse rate data according to the values in
the Integration Seconds and Periods to Average fields. After each integration period, the Pulse Count and
Frequency columns will be updated. The Average Frequency 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 finished. Due to speed limitations of the on-
board microcontroller, some higher pulse rates cannot be accurately collected.
