3.1.16.1 Save FROG as…Dialog Box
Enter the drive:\paths\and <filename> of the FROG File that you want to save. Press Browse…
if you want to overwrite an existing file, and you are not sure of the file’s name or location and
wish to search for it.
The FROG file format can be of two types, without a header or with a header. We recommend
that you use the header format to add to the unique identity of each FROG file.
Click on the Use Header Information check box to enable Header information to be
automatically placed at the start of the FROG data file. Default is for this box to be checked.
When it is not checked all the following items in this dialog box are disabled.

The item labeled Number of Delay Points automatically sets to the number of horizontal pixels
in the current beam.
The item labeled Number of Wavelength Points automatically sets to the number of vertical
pixels in the current beam.
The edit control item labeled Delay Increment, fs must be set by the operator to the delay per
pixel scale value. Units are femto-seconds. Control range is +/-10,000.000.
The edit control item labeled Wavelength Increment, nm must be set by the operator to the
wavelength per pixel scale value. Units are nanometers. Control range is +/- 10,000.000.
The edit control item labeled Center Wavelength, nm must be set by the operator to the value
of the wavelength at the center of the vertical column of pixels. Units are nanometers. Control
range is .001 to 10,000.
