Schloder SFT 1420 2 MHz Burst Generator

Schloder SFT 1420 2 MHz Burst Generator

IEC / EN 61000-4-4 The test generator SFT 1420 simulates quick transient noise interference as they are defined in the standard 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.

By increasing the number of pulses within the burst packet time-critical events may be tested in connection with the exact triggering of the SFT 1420. The generator includes several special functions such as "Real Burst" which simulates the natural appearance of the burst phenomena or „Sweep“ to simulate the bouncing of an electrical contact. The functions "IFM" and "DFM" (increasing and decreasing frequency) are powerful instruments to investigate resonance or saturation effects in the tested device. 

The easy operation and the clearly arranged front panel with the generator settings allows a time-saving and optimized testing in the fields of:

• Research and design: test with fixed standard values and investigations with variable settings (search for worst caste).
• Quality insurance: test with fixed standard values, manual adjustable or automatic test procedure by remote computer control.
• Service: handy unit an easy to be operated

All parameters like voltage, frequency, burst duration and burst period are variably adjustable.

Performance feature

• Functionality
  All burst parameters can be changed during a burst test. This guarantiees 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.

• Burst pulse in practice - Real-Burst
  The burst pulse occurring in practice does not comply with the definition. Its physical properties are deviating against the standard definition. The generator SFT 1420 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.

• High energy Burst generator 2 MHz
  Due to the high maximum burst frequency of 2 MHz up to 2000 individual pulses can be realized in a burst paket. The SFT 1420 is the world's only generator with this high burst frequency and allows very high-energy tests - e.g. drive control.
