The 501ADA-EQ Analog Distribution Amplifier is a general purpose amplifier for distributing 75 Ohms analog video signals. The 501ADA-EQ features one balanced equalized input with nine unbalanced outputs. The 501ADA-EQ amplifier has been designed to distribute a wide range of analog video signals. It can also distribute other pulses and signals that are less than 2V p-p. The 501ADA-EQ is housed in the 3RU 500FR frame that will hold up to 16 modules.
