IEC / EN 6100-4-4

The SFT 2400 with integrated coupling network simulates electrical fast transient (EFT) as defined in IEC 61000-4-4 standards. Due to very short rise time of 5ns, the individual pulses generate a broadband RF spectrum up to 300 MHz.

The simple operation takes place via a capacitive color touch display. All parameters are clearly displayed without nested menus and can be changed quickly by tapping and using a digital rotary encoder. The normative test levels 1, 2, 3 and 4 are programmed, additional test sequences can be stored via the memory function.

Performance features:

• Burst frequency: Single pulse up to 125 kHz
• Burst duration: 0.01 - 100 ms (limit parameters are automatically taken into account)

• Max. Pulses / packet: 500
• Trigger: manual or external
• HV output: coaxial socket
• Monitor output: BNC, TTL level
• Interface: USB (virtual COM port)
  Optional: optical (Toshiba LWL)
• Internal single-phase coupling network
• Weight: 9 kg

Functionality:
All burst parameters can be changed during a burst test. This guarantees that it can be easily and continuously to detect the fault threshold of the specimen. An interruption of the test for a parameter change at the burst generator is not necessary.

Burst pulse in practice - Real Burst:
The pulse burst occuring in practice does not comply with the definition of the standard. Its physical properties are deviating against the standard definition. The generator SFT 2400 provides the user a variety of special features such as "Real Burst", which simulates the natural appearence of the Burst pulse or "Noise" can be simulated with the contact bounce.

Time accurate triggering:
To localisation of faults, it is possible to couple the burst pulse very accurately to a certain process time of the EUT. The burst pulse microsecond exactly triggered with a jitter of <25 ns.
