Transient Limiter

Operating frequency range: 9 kHz to 200+ MHz
Insertion loss: 10 dB
Maximum input level: 2 W (+33 dBm), 12 V DC

Transient limiter protects sensitive and vulnerable input of spectrum analyser or EMI measurement receiver from spikes and surges generated by LISN (line impedance stabilisation network) during EMI testing.

Functionally it consists of HPF (high pass filter) followed by a 10dB attenuator and peak level limiter.

This device does not require any batteries or external power to operate.

It is functionally equivalent to HP/Agilent 11947A transient limiter.
