Takeda Riken (Advantest)TR4120

[cartronics]

Hi to all,

What a great website!!

I'm looking for a service or operator manual
for a Takeda Riken TR4120 which is a 0 to 30 meg spectrum analyser
which I bought at a radio rally,

it appears that the marker generator does not work!

Thanks for reading,
