Computers vary widely in their characteristics and performance. The exact pulse retrieval rate depends
on many factors including the speed of the processor, the speed of the bus, the speed of the memory,
and the graphics card. Typically, FROGscan runs from about 1 to 4 Hz on modern Core Duo computers
running a Windows 7 or later operating system.

FROGscan instruments are calibrated by the factory. Wavelength calibration is stored in the
spectrometer, and the temporal calibration is determined by the servo delay line. Typically, the delay line
is about 1 fs/step plus or minus a few percent. If you suspect that the temporal calibration is incorrect,
please contact the factory.
