  • Page 29: Operating Instructions

    2. OPERATING INSTRUCTIONS GENERAL Operation of the Model 1200A225B broadband amplifier is quite simple. The amplifier’s input signal, whether swept or fixed in frequency, is fed into the jack marked RF INPUT, and the amplifier’s output signal is taken from the jack labeled RF OUTPUT. The unit is turned on by activating the front panel POWER switch. In the event of a major malfunction, protection is provided by a circuit breaker located on the unit’s rear panel.

  • Page 45: Control States

    Model 1200A225B Remotely, the ALC Lockout state affects the Level Adjust and the Mode Select commands. In the locked state, the Level Adjust command for ALC Threshold, Detector Gain, and Response Time are simply ignored. This is also true of the Mode Selection. These commands can be issued to the amplifier while in the locked state, but their associated values will not change regardless of the Keylock position.

  • Page 65: Theory Of Operation

    3. THEORY OF OPERATION INTRODUCTION The Model 1200A225B RF amplifier consists of a .01-225 MHz RF amplifier assembly. The RF amplifier assembly consists of a pre-amplifier/driver module, and a four-way splitter that drives (4) final amplifier modules. These 4 final amplifier modules are combined through (1) four-way combiner to yield a combined power of 1200 watts or more.

  • Page 66: A7 Four-Way Combiner

    POWER SUPPLIES The Model 1200A225B contains five switching power supplies. The input voltage range to the power supply is 200–240 VAC, 50/60Hz. The AC input power is approximately 4000 watts. PS1 is a multiple output power supply. PS1 has a +5V, standby supply for the A14 control panel, the A15 remote interface board used for the remote interfaces, the -15V supplied to the A1 preamp and the A3 through A6 final modules.
