Spectrum Analyser Using Tek 465

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.

You could build a N2PK VNA which is pretty accurate.
