Transient Protection Devices

Transient Protection Devices

Spikeguard suppressors provide protection from transients originating from switching, lightning, and electromagnetic pulses including high power microwave threats. Spikeguards provide protection for sensitive electronic systems, data communication systems as well as for RF transmitters and receivers at their antenna transmission line terminals. They exhibit fast response through the UHF region, and are constructed from proven transmission line, gas discharge components, discrete silicon components, and can be subjected to many transients.



Fischer offers several types of pulsers as well as a customizable portable pulse generator. Pulsers drive current injection probes inductively couple current onto cables bundles.
