Transient Limiter LIT-930A

Typical Attenuation Chart · 9 kHz – 30 MHz

Frequency Range: 9 kHz – 30 MHz

Shields instruments during low-frequency conducted tests starting at 9 kHz — covering the full band for LISN-based conducted emissions testing.

Protects Spectrum Analyzer Input

Installs inline from LISN to receiver to clamp power-up surges, line disturbances, and long-duration inrush events before they reach the sensitive instrument input stage.

10 dB In-band Attenuation

Streamlines setups by replacing a separate 10 dB pad — delivering consistent input levels across operators and shifts without compromising measurement accuracy.

Reduces Overload from Out-of-band Signals

Cuts overload risk from out-of-band signals and mains-related energy, improving analyzer linearity and the detection of real emissions.

Ideal for Motors, UPS, and Large Power Supplies

Well-suited for applications where low-frequency noise and start-up transients are common — protecting instruments during demanding EUT test cycles.

Excellent VSWR — Clean 50 Ω Measurement Chain

Preserves a clean 50 Ω measurement chain with rugged N-type connectors for daily lab use, keeping reflections low and measurement uncertainty minimal.

Enhances Instrument Longevity and Test Throughput

Extends service life of measurement equipment and improves test throughput in both R&D and production environments, reducing repair costs and unplanned downtime.
