Why isn there any output from the “High Power RF Pulse Out” BNC connector?
A. First, please check if the high-voltage rectifier fuse has opened. Most often, this is due to a transistor failure in the gated amplifier module, typically resulting from the loss of any load on the gated amplifier output. Sometimes, however, the rectifier fuses become brittle and can open due to mechanical shock not an electrical problem. The fast-blow rectifier fuse is located in the round fuse holder on the rear panel of the RAM-10000. Typically, this fuse is a Bussman GBB-8 8 ampere 250V fast-blow rectifier fuse; older systems may have the GBB-6 6 ampere fuse. Please replace the fuse with the similar kind. Slow-blow or standard fuses should not be used as replacements because they will not provide adequate protection. If there is still no output after replacing the fuse, or if the fuse is still operational, please check if the trigger has not been accidentally programmed to computer trigger or external trigger. This can be identified by looking with the oscilloscope to see if th
