App 3: Recording
Some measurements are very time critical and need fast sampling of data. Since
Atto3 measures and computes the spectrum, the computation could delay the
measuring rate of an experiment. This app allows you to record the raw data in the
maximum allowed frame rate from the detector. The frame rate is determined by the
exposure time. After the raw data is captured, it is post-processed to obtain the
spectra files in the desired file format. The time interval between data recorded in
the file is given by (1/FPS) where FPS is the frame rate as displayed on the app
interface.
Standard Procedure
To initiate recording measurements, please follow the steps listed as under.
1
Please make sure that the spectrometer settings are in correct range
before starting the recording.
2
Check if Atto
3
is in Live Acquire mode. If yes, then click on stop and
disable the live mode.
3
Click on the Recording icon.
4
This opens a new dialog box for the recording app.
5
Select a folder where the data will
be finally stored.
6
Provide a scan name for the
measurement
to
identify
it
uniquely. Default name is set to
“Recording”.
7
Enter the file format for the final
output.
8
Enter the Number of Samples.
Number of samples are the
number of data points considered
for the measurement. At present,
the maximum number of samples
is set to 10000.
9
Enter the Capture Every
x
Frame parameter. The parameter
x
allows the
recording to skip (
x
-1) frames and sample for a longer measurement.
10 When the settings are in order, please initiate the recording by clicking on
Start button and wait for it to finish. At the end of the measurement, the post
