  • Generators PG-1 - PG-4 with the output signals in the form of step like function are used in TDR systems, for measurement of a characteristic impedance, a dielectric permittivity.
  • Generators PF1.1-PF5.1 with the output signals in a form of sine wave single period (monocycle) have got a spectral density concentrated near by some central frequency and are used in video pulse location systems as well as in UWB communications when the system bandwidth is limited
  • Generators PF-1-PF-4 with the output signals in a form of Gaussian function with additional small negative wave (monopulse) have the most uniform frequency spectrum and are intended for use as measuring for goals of objects frequency characteristics determination in time domain. They are also used in systems for measuring of broadband antennas (high to low frequency ratio more than 10).
