UPC/EAN: 860012796212
 
Meets EN/IEC 61000-4-4 & ISO7637
 
ECL50 (F) is designed for pulse calibration with a 50Ω load at the front input and a matching 50Ω output impedance which meets and exceeds EN/IEC 61000-4-4 & ISO7637. While the specification exceeds 400MHz (875ps rise time), our design at the 3dB bandwidth is over 500MHz achieving 700ps to ensure you have no doubt of capturing your pulse rise time (10% - 90%). This item mates directly to generators utilizing SHV connector.
