You could have fooled me. Still I guess everyone continues to learn at
some level or other, no matter how much they know.

Getting back to your external attenuator idea.
I often buy dud damaged boat anchor sig gens, for a few dollars
at ham meetings/trash and treasure buy and sells, in the hope of
finding a nice attenuator. I have humped a few monsters home
only to find rubbish inside. I have been lucky a couple of times.
There are plenty of ready made attenuator units for sale
usually for big dollars from a hobbyists point of view.

Have a look at this one.

How far is Farnam from you? Postage is 4 quid.
No information as to the maximum frequency but if you can
pick it up for a tenner it might be a good buy even if you use
it for low frequncies for something else. I am sure you spend
more that that at your local. Take a chance! Bid 10 max. :-)

Amazing! I don't know how you find this stuff, John. It seems like an
excellent buy, but there's just one small problem: the Zout of my AVO
appears to be 75 ohms. I know that's 'getaroundable' but it takes the
shine off it. I'll try changing the pots first, then I'll borrow a VNA
and see what gives.

Paul
