I have a spectrum analyzer (HP one), i only really use the LF input on it, that is up until now. The main input uses a large RF connector (totally forgot what these are called), it states on the input that it cant tolerate DC and DC should not exceed 0V. Origanaly i came with a DC block that screwed into the input, then what ever was connected screwed into that, since moving we no longer have the DC block, I tried ebay and got a shock at what they cost!!
So I wondered if it was possible to build one? I thought a capacitor would do it, but because of the cost of these blocks i assume there must be more to it than a simple capacitor.
Anyone got any information please, I dont want to damage the machine is was expensive and is a great bit of kit I want to look after. Especially now as my interest in amateur radio grows
