Transient Limiters to protect your Spectrum Analyzer input while performing conducted EMI emissions testing using LISNs

Transient limiter LIT-153 and LIT-930 protects a spectrum analyzer input from high-level transients from the line impedance stabilization networks during EMC conducted emissions testing. It has a combined frequency range of 9 kHz -30 MHz. The built in high pass filter helps reduce 50/60 Hz line feed through.
