Detector integration time
This should be adjusted for each experiment to maximize
the detector output and signal to noise ratio. The
integration time is reported in the status bar message
below the graph (as Time: xx milli-seconds). The toolbar
slidebar can be used to dynamically set the appropriate
level without saturating at the graph top.
Units configured as "non-XTiming" (special order), require
time selection in terms of Kilo Hertz (instead of milli
seconds), which relates to the Analog to Digital converter
conversion time in cycles per second (KHz).
//////////////////////////////////////////////////////////////////
Number of scans to average: 1..999
Sets the number of spectra to signal average. Please note that
the real-time display is updated AFTER this number of spectra
have been aquired. This option provides a smoothing in the Y
axis, effectively increasing the system signal to noise by the
square root of the number of scans being averaged. Set the
scan averaging to the highest number tolerable when there is
plenty of light signal and the detector integration time is
short. Even when you have a moderate level of signal, it is
best to wait a few seconds to improve the measurement quality.

Spectral smoothing controls: 0=>disable
Pixel Boxcar smoothing level 0..4 => 0/5/9/17/33
This performs data smoothing by applying a moving average of
adjacent pixels to the data arrays. For example, 1 would
average each 5 pixels with the 2 pixels on the left & right.
0 performs NO data smoothing. Smoothing levels 1..4
correspond to the input fiber image size for 50,100,200 & 400
micron diameter fibers respectively.
