Description
Com-Power Filter:
- Frequency Range 9kHz to 30MHz (Pass-band)
- 10 dB Attenuation (in-band)
- Typically Rented with LISN/Artificial Network
- Prevent Damage to Instrument from Voltage Spikes
- Act as a Band-Pass Filter to Attenuate Out-of-band Signals
- Excellent Input/Output VSWR < 1:1.2
Overview
Transient Limiter Limits input voltage when conducted EMI emissions measurement are conducted using Line Impedance Stablization Network (LISN). The EMC receiver input is connected live and neutral line of the product via the LISN. The LISN blocks the supply voltage from LISN RF portt but allow the RF signal to pass without much attenuation, so that it can be measured with a EMC receiver. Because the RF signal must be passed through, any short transients (a few microseconds or less) on the power supply lines will also be passed through. Trasient limiter LIT-930A protects the EMI receiver input from these short transients A transient with high enough energy witll damage a unprotected receiver input.
