Diode Pulse Limiter with built-in 10 dB high power attenuator and fuse lamp to protect sensitive measuring equipment when measuring spectra with high energy. Thanks to the built-in fuse lamp serious overload situations of sensitive equipment can be recognized fast and reliably.
A replacement bulb is placed inside the unit. The pulse limiter prevents expensive equipment defects. The very flat frequency response allows high measurement accuracy, even if only a few sample values are used for correction
