Burst-Generator SFT 1400 | 125 kHz

IEC / EN 61000-4-4

The test generator SFT 1400 simulates quick transient noise interference as they are defined in the standards IEC / EN 61000-4-4.

The single pulses show a very short rise-time (5 ns) and due to this a wide RF-spectrum up to 300 MHz. RF-interferences are the result.

The clearly arranged operating elements allow time saving and optimized tests. The memory function stores the normative test levels 1, 2, 3 and 4. In addition, own test sequences can be stored.

Numerous special functions such as Real Burst, Noise, IFM and DFM are included. With integrated coupling network and extensive accessories.

The SFT 1400 impresses with its extremely durable quality and optimum price-performance ratio.

The pulse burst occurring in practice does not comply with the definiton of the standard. Its physical properties are deviating against the standard definition. The generator SFT 1400 provides the user a variety of special features such as „Real Burst“, which simulates the natural appearance of the Burst pulse or „Noise“ can be simulated with the contact bounce. 

The functions "IFM" and "DFM" (increasing or decreasing frequency within a burst packet) are important tools for investigating resonance or saturation effects in the EUT

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 < 25ns. 

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 test specimen. An interruption of the test for a parameter change at the burst generator is not necessary.

    The optional EMC software "EMC-SOFT" enables the Schlöder interference generators to be operated from a PC. The required serial interface cables are supplied for the respective devices. With EMC-SOFT, all parameters that can also be set directly on the generator can be operated remotely.
