Transient Limiters

Multi-Stage Filtering

Combined low-pass and high-pass filters attenuate unwanted out-of-band energy before it reaches your receiver’s RF input stage.

Transient Suppression

Robust internal suppressors clamp high-energy voltage spikes from the LISN, preventing damage during power-up and switching events.

Impedance Matching

Two separate 5 dB attenuation pads (input and output) maintain a stable 50 Ω environment and minimise measurement uncertainty throughout the chain.

Critical Protection

Shields the RF Input of your EMI Receiver or Spectrum Analyzer from high-voltage transients and switching spikes generated during LISN-based conducted emissions testing.

Band-Pass Filtering

Functions as a band-pass filter to suppress out-of-band interference before it reaches the receiver — improving signal clarity and measurement integrity across the 150 kHz – 30 MHz range.

Stable Measurement

Maintains a precise 50 Ω impedance via N-type connectors, minimising reflection and keeping measurement uncertainty low for confident, repeatable results.

Setup Simplified

Replaces the conventional 10 dB external pad arrangement, reducing setup complexity and improving test repeatability without compromising measurement accuracy.

Shield Your Investment

Prevents catastrophic damage and minimises costly downtime — especially when testing equipment prone to high low-frequency noise such as motors, UPS systems, and large power supplies.

Enhanced Linearity & Accuracy

Functions as an integrated band-pass filter to suppress out-of-band energy, reducing the risk of receiver overload and intermodulation for superior signal clarity across 9 kHz – 30 MHz.

Integrated Design, Simplified Setup

Streamlines your test bench by replacing separate 10 dB external pads, reducing connection complexity and eliminating operator variability for consistent, repeatable results across every shift.

Rugged Lab-Ready Build

Features durable N-type connectors and maintains a precise 50 Ω measurement chain (VSWR Max 1.1:2), minimising reflection and keeping measurement uncertainty at an absolute minimum.
