12 DS676DB1
In the CS5466 Pulse Rate Output Window, the Pulse Count, Frequency, Average Freq and Standard Deviation are
displayed for the three energy-to-pulse outputs.
Count Span: The Count Span entry allows for a time period to be specified for counting the energy pulses output
by the CS5466. The Count Span is a decimal number having a range of 0.18 < Count Span < 167,772, with units of
seconds.
Periods to Average: The Periods to Average entry allows an average to be performed on the pulses counted during
the specified Count Span. The Periods to Average is an integer with a range of 1 < Periods to Average < 10,000.
Reset DUT: When this button is selected, the evaluation software will request the microcontroller to hardware reset
the CS5466. The CS5466 will perform a reset as discussed in the CS5466 data sheet.
Start/Stop: Initially the Stop button is hidden. When the Start button is selected, the evaluation software will instruct
the microcontroller to start counting the energy-to-pulse outputs from the CS5466. At this time the Start button is
disabled and the Stop button will appear. The evaluation software will then collect the Pulse Count over a duration
of time specified (in seconds) by the Count Span. The counted pulses will then be averaged over the specified Pe-
riods to Average entry. The Pulse Count and calculated Frequency, Average Freq and Standard Deviation will be
displayed at the end of the cycle.
