Spectrometer Integration Period
The spectrometer integration period is factory set.
The integration period should be as large as possible, to obtain a good signal; the
integration period must not be so large as to cause saturation of the signal.
The spectrometer integration time should not be changed, because the SUNA is
calibrated for the factory configured value.
Dark Averages and Light Averages
The spectrometer can perform internal averaging. Internal averaging reduces the noise
of a measurement at the expense of a reduced sampling rate. However, the sampling
rate is higher using internal averaging when compared to averaging the samples after
separate collection.
Another advantage of internal averaging is the reduction in the amount of data
generated.
Dark Samples and Light Samples
These parameters are used when
Operation Control
is set to
Samples
.
Dark and light samples are used in Continuous and Fixedtime mode, and control the
lamp off/on cycle.
Dark Duration and Light Duration
These parameters are used when
Operation Control
is set to
Duration
.
Dark and light duration are used in Continuous and Fixedtime mode, and control the
lamp off/on cycle.
