? Suggest you review a couple of web articles before digging into the rig with scope.? Typically if your trying to observe RF at the plate tank, there should be a RF sampler which brings the level down to scope range.
?
? Here are a couple of sites I found using a? search engine looking for "scope fundamentals" and "probe basics"
?
? Recommend that you research available probes and see what their specification limits are?before using one to probe a tank circuit.? And, I would strongly recommend staying on the cold side ((non HV) of the tank network.? Or, if needed, build a X10?attenuator into the rig to bring the levels down to managable voltages.

?
I have a 475 scope, but pretty much a beginner in its use. I want to measure RF frequencies in a ham tranceiver that could be as high as 800 VDC, and up to 30 Mhz. My question has to do with the proper type of probe. Is anything special needed to measure RF frequencies that could be generating significant power other than a common probe? Does the scope need protection from high power RF? I want to at least see what is going into the grids of the final amplifier tubes.
