  • Page 25: Operating Instructions

    2. OPERATING INSTRUCTIONS GENERAL Operation of the Model 30/20S1G18B broadband amplifier is simple. The input signal, whether swept or fixed in frequency, is fed into the jack marked INPUT and the amplifier output signal is taken from the jack labeled OUTPUT. The unit is turned ON by activating the power switch. In the event of a unit malfunction, protection is provided by a circuit breaker located in the AC input receptacle.
