I wonder if anyone knows of a project or kit that uses a 'scope timebase
output as the basis of an HF spectrum analyser. My aim is to make something
that would be useful for filter work so I'm not necessarily looking for
very wide frequency sweep.

TIA,


Charlie.

Hi Charlie,
For very little money, you can buy the miniVNA:

That will far outplay anything you can build. Because it makes use of a PC,
it will have features well beyond a simple SA + tracking generator. In
addition, it's a vector device.
