Transient Limiters

Transient limiters are specialised multi-stage protective components (often combining attenuators, clamping diodes, and high-pass filters) engineered to clamp fast, high-amplitude voltage spikes. Devices like the Tekbox transient limiter are critical when testing switching devices or operating in setups where sudden high-voltage transients can instantly fry delicate receiver inputs.

Why Choose a Transient Limiter?

Superior Equipment Safety: Safely clamps violent voltage peaks and spikes to protect costly spectrum analyzer and receiver inputs.
Integrated Design: Combines signal attenuation, high-pass filtering, and limiting into a single, compact device.
High Overload Resilience: Built to withstand heavy continuous RF power and high-surge conditions without degrading measurement integrity.
Future-Ready Bandwidth: Supports broad frequency ranges (up to 600 MHz and beyond) to accommodate modern pre-compliance testing standards.

Core Applications

Conducted Emission Testing: Placed directly between a LISN and a spectrum analyser to guard against surges.
DUT Switching Diagnostics: Protects measurement gear when Devices Under Test (DUTs) are abruptly switched on or off.
General Lab Protection: Acts as a generic front-end safety barrier for general-purpose RF bench testing.
EMC Pre-Compliance Setups: Essential safeguard for budget-friendly analyzers that lack robust built-in overload protection.
