DESCRIPTION
Both DSA and gain block amplifier in BVA304C are internally matched to 50 Ohms and it is easy to use with no external matching components required. The BVA304C always initialize to the maximum attenuation setting on power-up for both Serial and Parallel mode until next programming word is inputted.
