A look inside a Marconi signal generator #teardown #TestEquipment #Vintage #EE

On the Just another electronics blog, a Marconi Instruments signal generator is examined.

Recently I got a Marconi Instruments 2019 signal generator, capable of generating signals from 80Khz up to 1040Mhz. It can also modulate these signals with AM, FM and more. This instrument is from the mid 80s and is, as far as I can test, still in good operational order.

A signal generator capable of generating over 1Ghz is pretty impressive, especially in the 80s, so let’s have a look inside this unit and see how it’s made. I have very little RF knowledge, for a good explanation on how this thing works I would recommend the service manual. It can be found with some google magic and contains 240 pages filled with explanation of this signal generator.

Oh so many circuit boards, each photographed in detail!
