Teseq NSG 1025 Burst Generator
Description
Standards such as the IEC 801-4, DIN/VDE 0843-4 . CENELEC HD 481 .4, etc. call for interference voltage tests to be carried out on instruments and systems using pulse bursts like those that occur in practice when electrical equipment is switched on or off, or when it is plugged in or disconnected. Electronic circuits of all types, especially modern digital equipment, are very sensitive to these types of interference pulses.
The NSG 1025 Generator simulates such interference sources. The specifications of the pertinent standards are met and, particularly where precision and reproducibility are concerned, are often exceeded. A new type of solid-state high voltage switch ensures excellent pulse parameter stability and maintenance free continuous operation.
