The Burst SFT 1400 125kHz Schlöder transmitter simulates transient transient disturbances as defined in 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.

  • Boom frequency up to 125 kHz
  • All parameters can be changed during testing
  • DIN EN 61000-4-4, April 2013
  • Single pulse to explode forever
  • 5000 pulses/second. – 500 / pack
  • Correct activation
  • Various special functions.

Description

I. Specification of Burst transmitter SFT 1400 125kHz

Burst transmitter SFT 1400 125kHz Schlöder

  • 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.
  • Explosion pulses in practice: Actual pulses occurring Explosive pulses in practice do not conform to the definition of the standard. Its physical properties differ from standard definitions. The SFT 1400 125kHz Burst Transmitter provides the user with a series 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.
  • Precise triggering: To isolate the error, it is possible to precisely couple the burst pulse at a certain processing time of the test subject. Explosive pulse triggered with network precision with fluctuations <25ns.
