Thank you Nuvistor (wow! that was difficult to remember!), I do have that service sheet - what I have is an Aerial input and earth wanderplug sockets, and having stuck an earth onto a live chassis as a young teenager, did not want to put my nice Chinese signal generator to death so early in its career! Not terribly sure if I need to put the -ve of the bnc connection of the geny to earth, and worse still if I was injecting into a grid.
Next question relates to Lawrence as an answer- yes, the sig geny certainly has AM, and its output is digitally rendered into a little 'scope screen which displays it's shape and amplitude - question is, what level would I inject?
Thanks again, folks.
Dave
