  • Page 31: Operating Instructions

    2. OPERATING INSTRUCTIONS GENERAL Operation of the Model 5000A225C 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.

    3. THEORY OF OPERATION INTRODUCTION The Model 5000A225C RF amplifier consists of a .01-225 MHz RF amplifier assembly. The RF amplifier assembly consists of a pre-amplifier, driver amplifier module, a 4- way splitter to four 4-way splitters that drives sixteen final amplifier modules. These sixteen final amplifier modules are combined through four 4-way combiners, and a final 4-way combiner to yield a combined power of 5000 watts or more.

    POWER SUPPLIES The Model 5000A225C contains 22 switching power supplies. The input voltage range to the power supplies is 200–240 VAC, 47/63Hz. The AC input power is approximately 17,000 watts. PS1 is a multiple output power supply. PS1 has a +5V, standby supply for the A52 control panel, the A53 remote interface board used for the remote interfaces, A60 and A61 Switch breakout assemblies, K1 and K2 relays, and the A58 ALC PWB.

    LDMOS and other ESD-sensitive devices. Troubleshooting the Model 5000A225C in a logical manner can speed the solution to a problem. The settings of potentiometers (pots), capacitors (caps), or other variables should not be disturbed until other problems have been eliminated.

  • Page 69: General - Reading Faults

    If the fault does not clear with the RF drive off, some other problem exists in the amplifier. The digital control panel of the 5000A225C indicates the output power from the 5000A225C and the power reflected back to it. If the reflected power is very high, with respect to the forward power, this could indicate that the output coax cable is defective or that the load being driven has a high VSWR.
