Page 47: Theory Of Operation
3. THEORY OF OPERATION INTRODUCTION The Model 500W1000C RF amplifier consists of a 80-1000 MHz RF amplifier assembly. The RF amplifier assembly consists of a Pre-Amplifier (Pre-Amp), a Driver Amplifier (Driver Amp), an 8-way splitter, (8) final amplifier modules, an 8-way combiner, a directional coupler, and a detector. -

Page 51: Maintenance
4. MAINTENANCE GENERAL MAINTENANCE INFORMATION The Model 500W1000C requires very little maintenance since it is a relatively simple instrument. It is built with etched circuit wiring and solid state devices that will ensure long, trouble free life. However, should trouble occur special care must be taken in servicing to avoid damage to the devices or the etched circuit board. -
Page 52: Troubleshooting
GaN HEMTs and other ESD-sensitive devices. Troubleshooting the Model 500W1000C 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 53: 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 500W1000C indicates the output power from the 500W1000C 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. -
