The VTSD 9561 D from Schwarzbeck Mess - Elektronik OHG is a Diode Pulse Limiter that operates from DC to 200 MHz. It consists of a high-power attenuator along with an Osram 2306 fuse lamp that protects sensitive equipments when measuring spectra with high energy. The fuse lamp allows users to recognize over-load conditions quickly and reliably, thereby preventing possible damage. This limiter also includes a replacement bulb. This pulse limiter has an insertion loss of 20 dB and a flatness of ±0.5 dB. 

The VTSD 9561 D is available in a module that measures 28 x 36 x 88 mm and has BNC-type and N-type connectors. This diode pulse limiter is ideal for electronic protection applications.
