Normal
In the Normal (Free-run) mode, the spectrometer will
acquire one spectrum for each “get spectrum”
command issued from the host software. The
integration time for each spectrum is pre-
programmed prior to the host issuing its “get
spectrum” command.
The spectrometer waits in a
repetitive idling loop until it receives the next “get
spectrum” command.
Once the command is received,
the spectrometer exposes the detector for the pre-
programmed integration time, and its resulting
spectrum is written to an internal FIFO. The
spectrometer signals the host that a spectrum is
ready, and the host reads out the new
spectrum. Upon reading out the new spectrum, the
host immediately commands the spectrometer to
acquire the next spectrum. In this process, the
spectrometer is responding “on
-
demand” to the
host’s “get spectrum” commands.
The spectrometer
waits in an idle state between each spectrum and the
next
“get spectrum” command.
The spectrometer
does not pre-fetch any spectra in anticipation of the
next “get spectrum” command.
