In normal operation (non-burst mode), this is the datalogger scan rate, or the time series data interval.
If the measurement instruction that created the time-series data used burst mode (that is, the channel was entered as a negative number), the CR6 burst measurement sampling frequency is determined by the fN1 (first notch frequency) parameter, which can go up to a maximum of 93750 Hz (minimum sample interval of 10.667 uS). The SettlingTime parameter is used to delay once prior to beginning the burst. The total time prior to beginning the burst is the SettlingTime plus the ADC flush time (which is 810uS). The sample interval resolution is 1/93750Hz. The specified notch frequency will use the nearest multiple of (1/93750Hz) to get as close to the specified frequency as possible.
Type: Constant (or expression that evaluates as a constant)
