I. Specification of Burst generator SFT 1420 2MHz

Burst generator SFT 1420 2MHz  
  • The SFT 1420 noise generator simulates transient transient disturbances as defined by the IEC/EN 61000-4-4 standards. Due to the very short rise time (5ns), the individual pulses produce a wideband RF spectrum up to approximately 300 MHz RF interference results are results.
  • Function:
    • All burst parameters can be changed during cluster testing. This ensures that the noise threshold of the test equipment can be determined easily and continuously. It is not necessary to interrupt the test to change the parameter on the cluster generator.
  • Pulse explosion in reality:
    • Actual pulse occurs Explosive pulse that occurs in practice does not conform to the definition of the standard. Its physical properties differ from standard definitions. The Schlöder SFT 1420 2MHz Burst Generator offers the user a range of special functions such as "Real Burst", which simulates the natural occurrence of an explosive pulse, or "Noise", which can simulate contact bounce. The "IFM" and "DFM" functions (increase or decrease the frequency in an explosive package) are important tools for checking resonance or saturation effects in the equipment under test..
  • High energy pulse generator with 2 MHz:
    • Due to the high maximum pulse frequency of 2MHz, Schlöder's Burst generator SFT 1420 2MHz can execute up to 2000 individual pulses in a single package. The SFT 1420 is the only transmitter worldwide with this high burst frequency and allows for very high energy testing - e.g. drive control.
